Super Pro SPF3902-25.5K Sway Bar Mount Bushing Kit Polyurethane - 25.5mm

The Super Pro SPF3902-25.5K is a 25.5mm sway bar mount bushing kit engineered as a direct OEM replacement and performance upgrade for your vehicle's front stabilizer bar system. Manufactured by SuperPro — an Australian suspension specialist with over 40 years of industry experience — these bushings are purpose-built to restore and enhance sway bar performance where factory rubber components have degraded.

Why Replace Your Sway Bar Mount Bushings?

Sway bar mount bushings are responsible for anchoring the stabilizer bar securely to the chassis. OE rubber bushings are prone to warping, cracking, and compressing over time, allowing unwanted movement in the sway bar that reduces handling responsiveness and contributes to a loose, imprecise feel on the road.

Key Features:

• 25.5mm bore diameter — precisely sized to match the OEM sway bar specification
• Manufactured from SuperPro's proprietary polyurethane elastomer — engineered to exhibit the best characteristics of both rubber and plastic
• Superior durability over OEM rubber — resists compression, cracking, oils, water, coolant, and extreme temperatures
• Low NVH impact — carefully designed to minimize increases in noise, vibration, and harshness compared to typical polyurethane alternatives
• Internal knurling on many SuperPro bushings retains grease longer, reducing maintenance intervals
• Drop-in fitment designed to integrate with OEM hardware and mounting brackets — no universal or generic hardware
• Covered by SuperPro's lifetime warranty, including off-road, track, and competition applications

Upgrading to the SPF3902-25.5K restores lost sway bar performance, sharpens steering response, and improves overall body control — making it an ideal solution for both daily drivers and performance-oriented builds.
