For a more predictable, better handling car, upgrade to QA1 rear trailing arms, which solve flexing issues common to stock arms. These arms reduce bushing bind, allowing the suspension to move smoother for better control.
All upper tubular and lower boxed arms use greasable polyurethane bushings on both ends, while upper adjustable and lower tubular trailing arms use a spherical ball or rod end assembly on the chassis end.
Boxed arms are constructed from .120" wall cold rolled steel tubing for maximum strength and flex elimination. These trailing arms have fluted greasable, graphite/polyurethane bushings, which are superior to the stock rubber bushings.
Tubular arms are constructed of 1 1/4" diameter .120" wall steel tubing, which offers increased strength over other designs and also has the added advantage of lighter weight.
Adjustable arms allow easy rear suspension adjustments for optimum handling and traction. They can be adjusted without removing the arms from the vehicle; simply loosen the jam nuts and adjust the pinion angle. Spherical ball assembly with UHMW bushings allow rear suspension to move more freely. Includes greasable polyurethane differential bushings to replace soft OE differential bushings.
