QA1's Rectangular-Style Trailing 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 Trailing Arms are constructed of 1-1/4" diameter .120" wall steel tubing which offers increased strength over other designs, but also have the added advantage of lighter weight.
Heavy-Duty Adjustable Trailing 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 pinion angle. Spherical ball assembly with Delrin bushings allows rear suspension to move more freely. Graphite/polyurethane differential bushings replace soft OE bushings.
Trailing Arm Braces work with GM A-Body and G-Body trailing arms to accurately locate the rear suspension for major improvements in cornering, steering response, and traction with less wheel hop and more power to the ground. Braces include hardware. Sold in pairs.
All trailing arms except #122-5253 sold in pairs.
