Part#: 014453
Product: 4.5" Suspension System
Application: 1993-1998 Jeep Grand Cherokee ZJ
Read and understand all instructions and warnings prior
to installation of system and operation of vehicle.
BDS Suspension Co. recommends this system be installed by a professional technician.
In addition to these instructions, professional knowledge of disassembly/ reassembly procedures and post installation
checks must be known.
Certain BDS Suspension products are intended to improve off-road performance. Modifying your vehicle for off-road use may result in the vehicle handling differently than a factory equipped
vehicle. Extreme care must be used to prevent loss of control or vehicle rollover. Failure to drive your modified vehicle
safely may result in serious injury or death. BDS Suspension Co. does not recommend the combined use of suspension
lifts, body lifts, or other lifting devices.
You should never operate your modified vehicle under the influence of alcohol or drugs. Always drive your modified vehicle at reduced speeds to ensure your ability to control your vehicle under all driving conditions. Always wear your seat
Pre-Installation Notes
1. Special literature required: OE Service Manual for model/year of vehicle. Refer to manual for proper disassembly/
reassembly procedures of OE and related components.
2. Adhere to recommendations when replacement fasteners, retainers and keepers are called out in the OE manual.
3. Larger rim and tire combinations may increase leverage on suspension, steering, and related components. When
selecting combinations larger than OE, consider the additional stress you could be inducing on the OE and related
4. Post suspension system vehicles may experience drive line vibrations. Angles may require tuning, slider on shaft
may require replacement, shafts may need to be lengthened or trued, and U-joints may need to be replaced.
5. Secure and properly block vehicle prior to installation of BDS Suspension components. Always wear safety glasses
when using power tools.
6. If installation is to be performed without a hoist, BDS Suspension Co. recommends rear alterations first.
7. Due to payload options and initial ride height variances, the amount of lift is a base figure. Final ride height
dimensions may vary in accordance to original vehicle attitude. Always measure the attitude prior to beginning
1. Check all fasteners for proper torque. Check to ensure for adequate clearance between all rotating, mobile, fixed, and
heated members. Verify clearance between exhaust and brake lines, fuel lines, fuel tank, floor boards and wiring
harness. Check steering gear for clearance. Test and inspect brake system.
2. Perform steering sweep to ensure front brake hoses have adequate slack and do not contact any rotating, mobile
or heated members. Inspect rear brake hoses at full extension for adequate slack. Failure to perform hose check/
replacement may result in component failure. Longer replacement hoses, if needed can be purchased from a local
parts supplier.
3. Perform head light check and adjustment.
4. Re-torque all fasteners after 500 miles. Always inspect fasteners and components during routine servicing.

washers, running from the inside out. Torque bolt to 30 ft-lbs.
41. Ensure that the vehicle and axle are sitting level. Pull the spring collar up on the disconnect end and attach it to the
ball stud. Make sure that the disconnect end stud hole is square with the ball stud and tighten the jam nut against
the disconnect end. The disconnects allow for ½” of adjustment (1/2” longer from full-bottomed out). If necessary,
adjust the links side-to-side to compensate for any unevenness in the vehicle, allowing for the easiest possible
disconnecting of the ends.
42. Check the jam nuts to be sure they are securely locked off. Disconnect both end links and fold them up against
the sway bar. Clip the provided lanyard/clip assembly around the sway bar/end link and find the best position for
mounting the lanyard. This position will vary from vehicle to vehicle and with different suspension setups. Use your
best judgment. Use the provided self-drilling screws to mount the lanyard to the body/frame. (Fig 9).
Fig 9
43. With the lanyards installed reconnect the sway bar links to the axle. The lanyards can be reattached to themselves
so that they remain out of the way of moving parts when not in use.
44.Reattach center link to pitman arm. Torque nut to 35-40 ft-lbs. Install new cotter pin. Note: Do not back off nut to
install cotter pin.
45. Use provided zip-ties to keep brake line from interfering with suspension parts.
46.Reinstall wheels and torque lug nuts to specification, see owner’s manual.
47. With suspension hanging, inspect for interference. Turn wheels full turn from left to right while inspecting for
interference. Inspect front driveline for proper clearance and lengths. Return wheels/steering to center.
48.Remove jack stands and lower vehicle to the ground.
014453 Page 7
49. Grease and install bushings (M03406RB) and sleeve (55003) into adjustable track bar end. Thread jam nut onto
track bar followed by adjustable end. Make sure there is atleast 1” of thread engagement. Install straight grease
zerks into both ends of track bar. The grease zerk at the axle will face down to allow for access once the track bar is
50. Drill out the OE track bar axle mount to ½”. Do NOT drill the taper out.
51. Ball stud end is shipped assembled. See figures 10a, 10b, and 10c for rebuild instructions. Center the stud and
install into the original tapered frame mount. Use an 18mm wrench to hold the flats while tightening down the ½”
fine thread nylock nut with the 12mm flat washer. There will be a slight gap between the flats and OE mount once
installed. Tighten to 55 ft-lbs.
