Build a properly matched suspension or steering setup with this QA1 sway bars. Manufacturer part number 52862 is offered in the listed 52862 Front Sway Bar – 1977-1996 GM B-Body – Chevrolet Caprice / Impala / Buick LeSabre / Roadmaster / Oldsmobile Delta 88 / Pontiac Bonneville – 1-3/8 in. 4130 Chromoly configuration, so vehicle application, mounting position, dimensions, spring rate, adjustment range, and all notes must be confirmed before ordering.
Key Features
- Manufactured from hollow 4130 chromoly steel with a 3/16-inch wall and CNC-bent tubing, part number 52862 delivers a significant reduction in body roll without the weight penalty of a solid bar.
- Polyurethane bushings and plated mounting hardware are included.
- Hollow — CNC-bent, machined and welded bar ends.
- Chromoly has a higher strength-to-weight ratio than mild steel, so QA1 can achieve greater stiffness at a lower overall weight.
- CNC-bent tubing ensures consistent geometry across every bar, and the machined and welded bar ends eliminate the flex points that reduce the effective stiffness of simple bent-tube designs.
- The 1-3/8-inch diameter with a 3/16-inch wall is the result of QA1's application-specific tuning for the B-Body platform maximizing torsional stiffness where it matters while keeping unsprung weight low.

Sway Bars
Shop front sway bars, rear sway bars, matched anti-roll bar kits, adjustable sway bars, heavy-duty truck stabilizer bars, off-road Antirock systems, bushings, and service components at Black Ops Auto Works. This collection covers street cars, muscle cars, trucks, SUVs, Jeeps, European performance vehicles, Japanese sport compacts, autocross builds, track cars, and off-road applications. Sway Bars and Anti-Roll Bar Kits A sway bar, also called an anti-roll bar or stabilizer bar, connects the left and right sides of a suspension through a torsion spring. When the suspension moves differently from one side to the other, the bar twists and contributes roll stiffness. This can reduce body roll and change how lateral load transfer is distributed between the front and rear axles. Sway bars from Eibach, H&R, Hellwig, Progress Technology, aFe Control, PERRIN, Whiteline, SuperPro, UMI Performance, QA1, RockJock, Ridetech, Pedders, Cusco, COBB, Dinan, APR, Bilstein, and Skyjacker cover a w...

Adjustable holes can change effective rate, while material, wall thickness, arm length and mounting geometry also matter. Diameter alone does not establish equivalent stiffness across different designs.Bushings, Brackets and End LinksMount bushings must match the actual bar diameter and bracket shape.
