The QA1 78-96 GM B-Body Lower Boxed Trailing Arms are high-performance suspension components designed to improve handling and traction on classic GM B-Body vehicles from 1978 to 1996. Constructed from durable materials, the boxed trailing arms feature 0.120'' wall cold rolled steel tubing for maximum strength and flex elimination, while tubular versions use 1-1/4'' diameter steel tubing for increased strength and reduced weight. All arms incorporate greasable polyurethane bushings, which outperform stock rubber bushings, and feature a powder-coated gloss black finish for long-lasting durability. Heavy-duty adjustable options allow for precise rear suspension tuning, enabling quick pinion angle adjustments without removal. The spherical ball or rod end assemblies on the chassis end eliminate bushing bind, promoting smoother suspension movement and better control.
Designed as direct replacements for OE components, these trailing arms fit 1978–1996 GM B-Body models, including Chevelle, Caprice, and Impala, among others. They are suitable for street, track, or performance applications where improved handling and stability are desired. The kit includes pairs of boxed or tubular trailing arms, with adjustable versions offering easy rear suspension tuning. These arms are ideal for enthusiasts seeking a durable upgrade that enhances traction, predictability, and overall suspension performance, making them suitable for daily driving, racing, or restoration projects on compatible GM B-Body vehicles.

Overview
Overview
All upper tubular and lower boxed trailing arms use 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 to eliminate bushing bind, allowing the suspension to move smoother for better control. This keeps the tires planted firmly on the ground for improved traction and a more predictable, better handling car. For a long-lasting finish, tubular and boxed trailing arms are powder-coated gloss black, while the adjustable arms are zinc plated and anodized. Boxed Trailing Arms are constructed from 0.120'' wall cold rolled steel tubing for maximum strength and flex elimination. These trailing arms have fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings. Tubular Trailing Arms are constructed from 1-1/4'' diameter, 0.120'' wall steel tubing which offers increased strength over other designs, but also have the added advantage of lighter weight. These trailing arms have fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings. Heavy-Duty Adjustable Trailing Arms allow easy rear suspension adjustments for optimum handling and traction. Simply loosen the jam nuts and adjust the pinion angle without removing the arms from the vehicle. They replace soft OE differential bushings with polyurethane differential bushings, and they use a spherical ball or rod end assembly with UHMW polyethylene bushings on the chassis end to allow the rear suspension to move more freely and eliminate bushing bind. All parts sold in pairs.
