Product Description

The QA1 52851 is a rear sway bar kit purpose-built for big wheel and tire applications on 1971–1996 GM B-Body vehicles including the Caprice, Impala, Bel Air, LeSabre, Delta 88, and Bonneville. Unlike standard rear sway bars, the 52851 is specifically tuned in diameter and wall thickness for the geometry and weight bias of large wheel fitments -- delivering improved cornering grip and body roll control without harshness. The 1-1/4\" hollow 4130 chromoly bar provides the stiffness of a larger solid bar at a fraction of the weight.

CNC-bent tubing, machined and welded bar ends, and a gloss black powder-coat finish deliver both precision fitment and lasting durability. Greaseable graphite polyurethane bushings and plated hardware are included. Compatible with QA1 or OEM rear trailing arms. The frame-mount design makes this bar the recommended choice for B-Body wagon models, where standard axle-mount bars do not fit. For a complete front and rear big wheel kit, see QA1 52852. Made in Lakeville, MN and backed by a 1-year warranty.
