Mr. Gasket Traction Bar Wedge Sets

Mr. Gasket Traction Bar Wedge Sets are precision suspension components designed to restore proper rear suspension geometry on leaf spring–equipped vehicles. Constructed from die-cast aluminum for a balance of lightweight strength and long-term durability, these wedge sets introduce angular correction between the leaf spring pack and the traction bar mounting point — allowing precise pinion angle and traction bar geometry adjustment without cutting or welding.

Correct pinion angle is critical for minimizing driveline vibration and controlling axle wrap under hard acceleration. Whether compensating for weak, worn, or sagging leaf springs, or dialing in a modified chassis for street performance or drag racing, Mr. Gasket Traction Bar Wedge Sets deliver the angular correction needed to keep your rear suspension working as intended.

Key Features:

• Die-Cast Aluminum Construction: Lightweight yet durable material built to withstand the demands of performance street and strip use
• Pinion Angle Correction: Allows precise adjustment of pinion angle on vehicles equipped with leaf springs and traction bars
• Spring Compensation: Corrects for weak, worn, sagging, or modified rear leaf spring packs to restore proper traction bar geometry
• Axle Wrap Reduction: Proper wedge angle minimizes axle wrap and wheel hop under hard acceleration for more consistent, repeatable launches
• Improved Driveline Harmony: Optimized pinion angle reduces U-joint operating angles, limiting vibration and improving power transfer efficiency
• Sold in Pairs: Each set includes two matched wedges for balanced, symmetrical installation on both sides of the rear axle
• Multiple Angle Variants: Available in a range of wedge angles to suit a wide variety of traction bar configurations and suspension setups
• Emissions Compliant: Legal for sale or use on emissions-controlled vehicles, uncontrolled vehicles, and dedicated race vehicles

Now part of the Holley Performance family of brands, Mr. Gasket has been a trusted name in performance since 1964 — founded by drag racer Joe Hrudka and built on a legacy of parts that perform reliably under demanding racing conditions. Select the wedge angle that best matches your application from the available variants.
