Raise the vehicle to a safe and comfortable working height. 2. Support the axle and remove the leaf springs, shock absorbers and front leaf spring hanger. 3. The rear leaf spring shackle and hanger may also be removed but is not necessary. 4. The exhaust tail pipe & mounts will also have to be removed from the rear of the muffler back. A turn down can be installed or a custom tail pipe can be made. 5. The arm that attaches the rubber brake line to the frame must be removed, the brake line will reattach to the new upper cross member. 6. To allow maximum drop on this truck the frame must be notched. The template for the notch will locate off of the index hole shown below. 7. Scribe out the notch with a marker, then drill out the two corners with a ½” drill bit. This will give the cut a round edge and eliminate the possibility for stress fractures. 8. Support the rear section of the frame. Then cut the notch with a sawzall, cutoff wheel or plasma cutter. Grind all edges smooth. 9. Bolt the notch to the frame aligning it with the index hole in the frame and notch. Drill the remaining holes with a 7/16” bit. Use the 7/16” X 1 ¼” bolts, flat washers and Nylok nuts to secure the notch to the frame. Be sure to leave the rearward bolts out until the upper shock cross member has been installed. See the next step. 10. Bolt the upper cross member to the frame using 7/16” x 1 ¼” bolts, Nylok nuts and flat washers. It will attach to the bottom side of the frame rail & notch. 11. Attach the brake line to the tab on the upper cross member. It may be necessary to bend the brake line to attach it to the cross member. 12. Thread the 5/8” upper shock stud into the cross member. 13. Raise the lower bridge up to the leaf spring pad. Place the upper axle plate on top of the leaf spring pad and secure with four 5/8” x 6” bolts, Nylok nuts and flat washers. Tighten them evenly. Note: It may be necessary to tweak the brake lines a bit to clear the bridge assembly. 14. Install the 5/8” shock studs into the lower bridge. 15. Bolt the 4 link frame mount to the frame utilizing the factory hanger bolt holes. These holes must be drilled out to 7/16”. Secure the assembly with six 7/16” x 1 ¼” bolts, Nylok nuts and flat washers. 16. Attach the upper and lower bars to the frame bracket using the 5/8” x 2 ¾” bolts and Nylok jam nuts. The centerto-center measurement on the bars should be 26.5”. Note: Be sure to tighten the bar bolts with the axle at ride height. 17. Attach the upper and lower bars to the axle bracket assembly with 5/8” x 2 ¾” bolts and Nylok jam nuts. Note: After attaching the bars, make sure the rod end jam nuts are tight. 18. Bolt the panhard bar axle bracket to the diff. cover using three 5/16” x 2” bolts, flat washers and lock washers. 19. The brake line will be relocated using the “L” bracket supplied with the kit. Secure the splitter to the “L” bracket with the 5/16” x 1 ½” bolt, Nylok nut and flat washers. Note: The brake lines will need to be rebent or new lines can be made. 20. Attach the panhard bar to the stud using the large fender washer and 7/16” Nyloc nut. The center-to-center measurement on the panhard bar is 17 ½”. 21. The other end of the panhard bar will attach to the cross member with a 5/8” x 2 ¾” bolt and Nylok jam nut. 22. Install the 2” bump stop into the notch. If you wish for the vehicle to drop an extra 1 ½” a shorter bump stop can be installed, but a hole must be cut in the bed floor to allow clearance for the differential. Note: We offer a ½” tall bump stop, Part # 90001082 23. Install the shock absorbers between the upper cross member and lower bridge using the supplied hardware. 24. Apply thread sealant to the air fitting and screw it into the top of the air spring. Fasten the air spring to the upper mount and lower bridge using three 3/8” x 3/4" bolts, flat washers and lock washers. Do not overtighten these bolts, they just need to be snug. Over tightening could pull the inserts out of the air spring. 26. To allow clearance for the C-Notch a section must be removed from the bed floor brace. This section is approximately 4” wide and about 7 ½” from the fender well. 27. Check air spring, brake line & parking brake cable clearance through full suspension travel. Allowing the air spring to rub on anything will result in failure and in not a warrantable situation. 28. Ride height on this air spring is approximately 9” tall; should be around 60psi.
