Upgrade your rear suspension with the SuperPro SPF3108‑16K Rear Sway Bar Mount Bush Kit — a direct-fit replacement kit designed to restore proper sway-bar function and chassis stability. Over time, stock rubber bushings compress and wear out, allowing unwanted sway-bar movement. This can result in sloppy handling, poor body control, and reduced cornering precision. The SPF3108‑16K kit replaces those weak points with durable polyurethane bushings engineered to maintain firm, consistent sway-bar mounting under load.
SuperPro’s high-quality polyurethane compound resists oil, water, road salts, and temperature extremes — far outlasting standard rubber bushings and preserving handling performance even under harsh conditions. The kit is designed to fit original equipment hardware and mounting points, ensuring proper fitment and reliable operation. With improved sway-bar anchoring, you get tighter, more responsive handling, reduced body roll during cornering, and better overall chassis balance.

Polyurethane sway-bar mount bushings
Steel sleeves/tubes and any necessary mounting hardware
