INTRODUCTION

Congratulations on your purchase of a hydroformed front frame from Detroit Speed, Inc. This all new front frame is a bolt in replacement for the original stock front frame and greatly improves handling and ride quality by utilizing DSE’s unique suspension geometry. It is the only front frame in the aftermarket industry with hydroformed frame rails. The hydroformed frame rails feature high strength and stiffness, decreased weight, and precise quality and repeatability. Hydroforming preserves the steel’s strength and stiffness because it is performed at low temperature, unlike traditional high temperature processes which decrease material strength.

The DSE front frame has been designed, engineered, and developed for the road and track. This front frame blends the benefits of current OEM technology and aftermarket performance into one product.

The DSE front frame has the following features:

 Hydroformed framerails and stamped crossmembers

 Optimized suspension and steering geometry

 Ability to accommodate small and big block Chevrolet engines as well as LS1, LS2, and LS7 engines

 Fits within stock inner fenders on a 1969 Camaro without modifications. 1967-1968 Camaros may require modifications to the inner fenders.

 Aluminum body coilover shocks with “Detroit Tuned” valving

 Splined Anti-Roll bar

IMPORTANT:

If the lower control arm ball joint stud needs to be serviced after the initial torque setting listed above for a coilover spring change, etc. use the following information to re-assemble the lower control arm and upright:

1. Before you remove the ball joint nut, make a line with a marker from the top of the nut down to the upright and then loosen the ball joint nut.

2. Upon re-assembly, torque the ball joint nut to 20 ft-lbs. and then tighten the nut until the line on the nut goes back to the line on the upright so it is back in the same location as the initial torque setting.

DSE Bolt-on Z-bar Bracket (P/N: 032101): If you purchased the Bolt-on Z-bar Bracket, Detroit Speed has a bracket for this application. The Bolt-on Z-bar Bracket provides a simple and effective way of mounting a bracket to the front frame for the factory Z-bar bracket.

1. Pilot holes for the Bolt on Z-bar Bracket are located in the frame rails. The appropriate holes in the front frame must be drilled larger to be tapped. These holes are shown in Figure 2.

Pilot Hole

Drill these holes

Figure 2 – Locating the holes to be drilled

2. Drill the holes out using a “J” drill bit. Using the appropriate tools, tap the drilled holes to 5/16”

– 24.

3. Before bolting the DSE Bolt-on Z-bar Bracket to the front frame, attach the factory Z-bar support.

Use the provided hardware to attach the Z-bar Bracket to the front frame.

NOTE: Be sure the frame rails are free of any loose media or particles that may have collected in the rails from paint or powdercoat. Do this with compressed air. Pay particular attention to the front crossmember.

Any foreign particles left in the front crossmember could possibly damage the Anti-roll bar end support bushings.

DSE-F501-72 (7/23/2014)

1. Install lower control arm assemblies. a) Locate the correct lower control arm (driver or passenger side). This is referenced by the bump stop located on the forward leg of the front frame. See Figure 3.

Bump Stop

Figure 3 – Passenger side control arm shown

b) Be sure to use the correct bolts to mount the control arms. The short bolt (9/16-18 x 3 ½”) is used in the forward leg of the control arm and the long bolt (9/16-18 x 3 ¾”) is used in the rear leg of the control arm. Both bolts must point forward (i.e. bolt head toward the rear] or the bolts and the control arm will not be able to be removed once the front frame is fully assembled.

2. Install each coilover assembly. a) Before installing each coilover, it is necessary to build each assembly.

For the

base, non-adjustable shocks

please use the following steps to assemble each coilover shock:

(1) Assemble the coilover shock by removing the snap ring using a set of snap ring pliers to remove the upper spring seat as seen in Figure 4.

(2) Once the upper spring seat is removed, the coilover adjuster nut must be threaded all the way to the bottom of the threads. Then you can install the Torrington bearing set (See Figure 5) on each shock by installing one thrust washer, followed by the roller bearing and then another

Figure 5 – Torrington Bearing Set Figure 4 – Removing the Snap Ring

(3) With the Torrington bearing set in place you can now install the spring over the end of the shock.

(4) With the spring in place, install the upper spring seat along with the snap ring as seen in Fig. 6.

DSE-F501-72 (7/23/2014)

Page 5 of 16

Figure 6 - Snap Ring Installed

For the

adjustable shocks

, please use the following steps to assemble each coilover shock:

(1) Remove the upper spring seat from the retaining ring using a rubber hammer and moving it down off the upper shock mount as seen in Figure 7.

(2) Remove the retaining ring from upper shock mount and pass the upper spring seat over the upper shock mount as seen in Figure 8.

(3) Thread the spanner nut all the way to the bottom of the coilover shock and install the Torrington bearing set (See Figure 5 above) on each shock by installing one thrust washer, followed by the roller bearing and then another thrust washer.

(4) Slide the coilover spring over the top of the upper shock mount.

(5) Install the upper spring seat back over the top of the upper shock mount and re-install the retaining ring back onto the upper shock mount. Press the upper spring seat up onto the retaining ring so it locks in place.

The coilover assembly in now complete and ready to be installed.

Figure 7 – Removing the Upper Spring Seat Figure 8 – Upper Spring Seat & Retaining Ring b) Make sure the upper mounting hole is clean and free of any paint so the bolt and spacer slide into the mounting tab. c) Slide the ½” upper bolt with spacer through the eyelet and install the ½” Nylock nut and washer from the shock hardware bag provided. d) Position the lower coilover mount to the lower control arm. Install the lower shock retaining bolts from the top side of the control arm so that the washer and nut are on the bottom of the LCA.

Torque all coilover and LCA hardware. Figure 9 shows a completed and installed coilover spring.

DSE-F501-72 (7/23/2014)

4. Install the bump stops for the upper control arms.

5. Install the rack and pinion assembly. a) When installing the rack and pinion, protect the opening in the crossmember to avoid paint chips as it gets very tight in several areas. Install the rack and pinion assembly from below the crossmember for better clearance and easier alignment. b) The steering output shaft must be positioned with the flat of the shaft pointed upward. Refer to the arrow in Figure 11. With the steering shaft turned correctly so that the flat surface on the splined steering shaft points up and forward, rotate the rack to the rear of the front frame to install in the crossmember. Figure 12 shows the rack installed.

DSE-F501-72 (7/23/2014)

Page 7 of 16

Figure 11 – Positioning the Steering Shaft Figure 12 – Installed Rack c) Once the rack is in place, slide the aluminum spacers in place between the rack and the forward crossmember and install the bolts. Use anti-seize on the bolts and torque to 95 ft-lbs.

6. Install the outer tie rod ends. a) Apply anti-seize to the tie rod end threads, then thread the outer tie rod ends onto the rack and pinion. b) When installing the tie rod ends, make sure they are equal distance on each side to center the steering. This measurement should be approximately 2 ¼” per side. Measure this from the end of the threads to the outer edge of the nut. c) Thread the grease fittings into the tie rod ends.

7. Install the Anti-Roll bar. a) Lube the outside of the composite bushings with soapy water. Lube the inside of the bushing, and do your best to fill the interior bushing grooves with chassis grease. b) Before sliding the Anti-Roll bar in place, clean the outside of the bar thoroughly with lacquer thinner to remove any foreign materials from the bar. c) Once the bar is clean, slide the bar in place. After the bar is in place, install the composite bushings.

The bushings may not push in completely by hand. Do not be concerned, as they are designed to be a very precise fit. With the bar and both bushings installed, use a large diameter socket and a rubber hammer to seat the bushings on both sides at this time. See Figure 14.

Figure 13 – Installing the Bushing & Anti-Roll

Bar

Figure 14 – Fully Installing the Bushings

d) After installing the bar and pushing the bushings in all of the way, center the bar in the crossmember.

Measure the portion protruding from the bushings on each side as in Figure 15 and adjust accordingly until this measurement is the same on both sides. Make sure to reseat the bushings

DSE-F501-72 (7/23/2014)

Page 8 of 16

against the frame before measuring, as they can shift when you move the bar and throw off your measurements.

Figure 15 – Measuring the Anti-Roll Bar

e) Install the Anti-Roll bar shaft clamp next. Loosen both allen screws in the lock collar. Apply Medium

Strength Loctite 242 to the threads and position the clamp onto the Anti-Roll bar. With the heads of the bolts accessible from the bottom, torque the bolts. NOTE: Be sure that the groove in the clamp is installed so that it points to the center of the front frame and the size marking is to the outside, and that the two clamps match on either side. See Figure 16.

Figure 16 – Indexing the Clamp

8. Install the Anti-Roll bar arms to the Anti-Roll bar tube. a) Make sure both arms are positioned the same on the splines and are even in relation to one another. b) When both arms are on the same splines, bolt them in place. The bolt will go through the arm and line up with the groove in the end of the Anti-Roll bar tube. Install the bolt from the bottom so that the nut is on top of the bar. The bolt will not be able to be removed after it is fully assembled. c) Torque the Anti-Roll bar arm retaining bolt.

DSE-F501-72 (7/23/2014)

Page 9 of 16

9. Install the Anti-Roll bar end links to the lower control arm. a) These must be installed on the lower control arms now as tightening the links later can be very difficult. b) Use the included Nylock nut and washer. When installing the lower Nylock nut, use High Strength

Red Loctite 262 on the threads. c) Torque the lower nut to the correct specification.

10. Connect the Anti-Roll bar arm to the end links. a) Connect the Anti-Roll bar arm to the Anti-Roll bar end link on either side. Use High Strength Red

Loctite 262 on the threads when installing the jam nuts and washers and torque. b) Reposition the lower control arm on the side that is being installed last. c) Install the upper Anti-Roll bar end link nut to the Anti-Roll bar arm. Again, use High Strength Red

Loctite 262 on the threads and torque.

11. Install the spindle assembly. a) Clean any grease from the upper and lower ball joint studs and the spindle holes with a clean rag and lacquer thinner. b) Install the spindle to the upper control arm first. NOTE: Turn and position the stud so the cotter pin locates from front to rear to ease installation. c) Tighten the upper ball joint nut to the appropriate torque setting and install the cotter pin. d) Place the spindle on the lower ball joint. NOTE: Turn and position the stud so the cotter pin locates from front to rear to ease installation. e) Tighten the lower ball joint nut to the appropriate torque setting and install the cotter pin. NOTE: It is critical to follow the torque procedure listed in the table on page 3 and to use High Strength Red

Loctite 262 on the lower ball joint threads. f) Insert outer tie rod end into the spindle and torque. Install the cotter pin.

12. The front frame is assembled at this point. Figures 17 and 18 show a completed installation. Doublecheck to ensure that all installed components are tight and torqued correctly.

Figure 17 – Fully Assembled View (Driver side, Front)

Figure 18 – Fully Assembled View (Driver side, Rear)

13. Install the front frame in the vehicle. It is very important that the front frame be centered in the vehicle. a) Position the vehicle on level and solid ground. Support the vehicle using jackstands at four corners of the body. b) Locate the lower control arm forward mounting locations and drop a plumb line to the ground and mark the locations. c) On the rear of the car, locate the round flanged hole in the frame rail that is next to the rear spring pockets. Drop a plumb line from this location on both sides and mark the locations. d)

Measure diagonally from these locations to see if the front frame is square. The difference between the two measurements should be 1/16” or less. If the front frame is not square, loosen the front frame mounts and reposition.

14. When installing the front frame in 1968-1974 Nova applications, it is necessary to use the factory

Body Mount Spacers. The spacers install at the forward body mounts and install between the body mounts and the body. The spacers can be seen in Figure 19.

Figure 19 – Nova Body Mount Spacers

15. After the front frame is installed into the vehicle, the power steering hoses can be attached to the steering gear. Follow Figure 20 for the location of the pressure and return ports.

16. The front frame is now assembled and installed. NOTE: Be sure to lubricate all points on the front frame with quality chassis grease. Detroit Speed offers Driven Extreme Pressure chassis grease available as P/N: 140103 if needed.

17. When installing the engine in the front frame on LS7 applications, the DSE Hydroformed Front frame is designed to accept the stock oil pan and drain plug. However, the design does not allow the drain plug to be functional. To drain the oil from the engine, the hose adapters on the oil pan must be used. The manufacturer and part numbers for the hose adapters are shown in the engine fitment section on page

2. Follow the manufacturer guidelines for the installation of this hose kit.

18. Setting the vehicle ride height. a) With the vehicle assembled with all components installed, adjust the ride height as necessary. Detroit

Speed does recommend using a small wipe of anti-seize before adjusting the spanner nut and compressing the coilover spring. b) Detroit Speed does include a Spanner Tool (P/N: 031060) to adjust ride height however if you have the adjustable coilover shocks, Detroit Speed does offer an Adjustment Tool available as P/N:

031061 if needed. A photo can be seen in Figure 21.

High-Speed Adjuster (12 Sweeps)

The high-speed adjuster is a “sweep” style adjuster meaning that its adjustment is measured by the location of the adjuster in the eyelet window. It uses a left-hand thread in its operation which means; as you increase high-speed, the adjuster will move down in the window*. The high-speed adjuster’s reference position is full soft and referred to as +0 (+0 = full soft, +12 = full stiff).

Low-Speed Adjuster (25 Clicks)

The low-speed adjuster is a “clicker” style adjuster meaning that its adjustment is measured by detent grooves located inside the high-speed shaft. It uses a right-hand thread in its operation which means; as you increase low-speed, the adjuster will move up in the window. The low-speed adjuster’s reference position is full stiff and referred to -0 (-0 = full stiff, -25 = full soft).
