Replacement Threaded Stem / Sway Bar Adjuster

The Replacement Threaded Stem / Sway Bar Adjuster from JOES RACING PRODUCTS is a precision component engineered for racers and suspension tuners who demand fine-grained control over vehicle dynamics. This threaded stem assembly allows real-time adjustment of sway bar stiffness, enabling drivers to dial in the exact anti-roll characteristics needed for track performance, cornering balance, or street-strip versatility. Whether you're running a circle track, road course, or drag setup, this replacement adjuster restores critical tunability to your suspension geometry.

Constructed from hardened steel with a fully threaded design, the stem maintains precise load-bearing capacity under sustained lateral forces and track stress. The threading allows incremental adjustment without requiring complete sway bar removal—a key advantage when you're making setup changes between heat cycles or qualifying sessions. JOES RACING PRODUCTS' engineering ensures concentricity and thread integrity across the adjustment range, preventing binding or cross-threading that could compromise suspension response. The 6.25-inch length and 1-inch diameter provide compatibility with standard racing suspension packages, while the 1.51-pound weight keeps unsprung mass minimal.

This replacement stem is ideal for competitors running single-adjustable or dual-adjustable sway bar systems who need a wear-resistant upgrade or mid-season replacement. Installation is straightforward for anyone with basic suspension knowledge—thread the stem into the adjuster body and lock it in place at your desired preload setting. Compatibility spans most modern racing chassis and many road-course-equipped street vehicles using JOES sway bar kits or OEM-compatible aftermarket suspensions. Keep a spare on hand for pit-day adjustments, or stock multiple units if you're running a multi-car operation.
