Upgrade your front suspension with the SuperPro SPF3096‑21K 21 mm Front Sway Bar Mount Bush Kit — a direct-fit replacement for worn or degraded OEM sway-bar mount bushings. As sway-bar mount bushes age, they tend to soften, compress, or deform, leading to slack in the anti-roll bar system. This can reduce sway-bar effectiveness, causing sloppy steering feel, increased body roll, and inconsistent handling.

The SPF3096‑21K kit replaces those weak points with high-quality polyurethane bushings engineered to maintain a firm, consistent connection between the sway bar and chassis. Polyurethane resists oil, water, road salts, and temperature extremes — offering significantly greater durability and longevity than standard rubber mountings.

With the upgraded bushings installed, you’ll experience tighter steering response, improved chassis stability under cornering or braking, reduced body roll, and a more direct, confident driving feel. Installation is straightforward and can typically be completed in about 1 hour.

Kit Details:

• Polyurethane sway-bar mount bushings (front)

• Steel sleeves / internal tubes as needed

• Designed to fit OEM mounting points and hardware

Position: Front sway-bar mounts
Installation Time: ~1 hour
Warranty: Lifetime

This kit is ideal whether you’re restoring worn suspension components, upgrading for better handling, or maintaining your car’s performance over the long term.
