Edelbrock Adjustable Trailing Arm is fully assembled, greased, and ready to install.
1. Install Edelbrock adjustable trailing arm into trailing arm support bracket using supplied spacers. Spacers have a lip
on them that goes into heim joint. Install OEM bolt in the same direction as the factory. Use blue Loctite™ and torque
bolt to 90 ft./lb.
2. Re-install trailing arm support bracket and trailing arm in vehicle. Use blue Loctite™ on threads and torque to
70 ft. /lb.
3. The trailing arm should then pivot smoothly.
4. Pivot trailing arm into position over OE bushing. Install rear bolt in same direction as original.
5. Place one drop of blue Loctite™ on clean threads and torque the nut to 90 ft./lbs.
6. Although Edelbrock Trailing Arm is pre-lubed, you may want to finish your installation by lubing the front bushings with
a greasegun. Be sure to replace the dust caps on the Zerk fittings to prevent dirt and corrosion from damaging the
fitting.
Check all nut and bolt tightness after first 10 miles.
NOTES:
1. Edelbrock Adjustable Trailing arms come pre-adjusted to stock length. Pinion angle can be adjusted by loosening the
jam nuts on the arms and turning the aluminum adjuster sleeve in the center of the arm. Both arms should be
adjusted evenly. A properly installed and adjusted trailing arm will have the spherical ball straight and parallel with
the ball housing. If the ball is twisted in its housing when installed, the arm could fail during suspension articulation.
After adjustment has been made, use a drop of Loctite™ on threads at jam nuts.
2. Jam nuts should be checked periodically for tightness.
