QA1 REAR TRAILING ARMS [Lower | Tubular] (2005-2014 Ford Mustang)

For a more predictable, better handling car, QA1 rear trailing arms solve flexing issues common to stock arms. These arms eliminate bushing bind, allowing the suspension to move smoother for better control.bAll upper tubular and lower boxed arms use greaseable 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, greaseable 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 being lighter. These also use greaseable bushings.

ADJUSTABLE ARMS allow easy rear pinion angle 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 allows rear suspension to move more freely. Includes polyurethane differential bushings to replace soft OE differential bushings.
