QA1 5204 Lower Trailing Arms 78-88 GM A/G Body Rectangular Steel

QA1's Rectangular Lower Trailing Arms are engineered to replace weak factory components with superior strength and performance. Constructed from .120" wall cold rolled steel tubing, these trailing arms deliver maximum strength while eliminating flex under hard acceleration and cornering loads.

Key Features:

• Heavy-duty .120" wall cold rolled steel rectangular tubing construction
• Fluted, greasable graphite/polyurethane bushings for improved durability and performance
• Eliminates deflection and wheel hop associated with soft factory rubber bushings
• Direct bolt-in replacement for 1978-88 GM A-Body and G-Body vehicles
• Sold as a pair for complete lower trailing arm replacement

The upgraded graphite/polyurethane bushings provide consistent performance across temperature ranges while remaining serviceable through integrated grease fittings. These trailing arms are ideal for street performance, autocross, and drag racing applications where improved rear suspension control is essential.
