SuperPro KIT5115RK Polyurethane Rear Suspension Bushing Kit for Triumph Spitfire MkIV & 1500

The SuperPro KIT5115RK is a complete polyurethane rear suspension bushing kit engineered specifically for the Triumph Spitfire MkIV and 1500. Designed as a direct replacement for worn OEM rubber bushings, this kit restores and enhances the rear suspension geometry of your classic Spitfire with long-lasting, high-performance polyurethane components.

Why Upgrade to SuperPro Polyurethane?

Original rubber bushings are prone to deterioration over time and are designed only for standard loads and ride heights. SuperPro's proprietary polyurethane formulation outlasts rubber and maintains consistent suspension geometry, keeping your Spitfire handling precisely as intended — or better.

Key Features:

• Manufactured from SuperPro's proprietary polyurethane compound, developed and refined over 40+ years of motorsport testing
• Dramatic improvements in rear-end handling and cornering precision
• No increase in vibration or ride harshness compared to OEM rubber — suitable for both road and track use
• Reduces rear axle instability, passive steer, and vehicle wander, especially under braking
• Significantly more durable than OEM rubber, resisting oils and environmental contaminants
• Engineered and developed in-house by SuperPro for precise fitment to Spitfire MkIV and 1500 rear suspension
• Includes all bushings required for a complete rear suspension rebuild
• Backed by SuperPro's 3-Year / 36,000-Mile Guarantee
