QA1 REAR TRAILING ARMS [Upper | Adjustable] (1968-1972 GM A-Body, 1969-1972 Pontiac Grand Prix & 1970-1972 Chevrolet Monte Carlo)

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.

BOXED ARMS are made from .120" wall cold rolled steel tubing for maximum strength and flex elimination.
TUBULAR ARMS are constructed of 1-1/4" diameter steel tubing, which offers increased strength over other designs and also has the added advantage of lighter weight.
ADJUSTABLE ARMS allow easy rear pinion angle adjustment for optimum handling and traction, and they can be adjusted without removing the arms from the vehicle.
