Application: Designed for full size GM SUVs. These trailing arms are designed to stabilize the rear suspension, while
improving suspension articulation.
Suggested Tools for Installation:
❑ Jack and proper load rated jackstands
❑ 21mm combination wrench
❑ 21mm 1/2” drive socket and ratchet
❑ Hammer
1.
Raise vehicle and support with jackstands on a stable surface.
Note: Vehicle must be supported with vehicle’s normal weight on rear axle. Do not support vehicle by its trailing
arms.
2.
Remove only one of the stock lower trailing arms.
3.
Install the Edelbrock lower trailing arms with the spherical ball at the rear axle mounting point and the grease
fitting on top of the arm. It may be necessary to spread the rear end mounting tabs slightly to install trailing arm.
4.
Re-install stock trailing arm bolts and torque bolts to 140 ft. lbs.
5.
After one side has been completed, repeat steps 2, 3, & 4 on other side of vehicle.
6.
Edelbrock trailing arms are greased during assembly, but we recommend you grease them after installation and
during normal service.
7.
Check bolt torque periodically.
NOTE: To lube the spherical ball end of the trailing arm, the vehicle’s full weight must be on all four tires. This will
allow you to grease the zerk fitting that is located on the top rear of the arm. If the suspension is hanging,
you will not be able to access the zerk fitting.
To lube the front trailling arm bushing, you will need to remove the plastic cover at the front of the trailing
arm. Re-install plastic cover after lubing.
