🏁 Key Benefits
- As Stiff as Solid Steel, Without the Drawbacks: Enjoy the strength and stability of solid mounting without harsh vibrations and noise. Our polyurethane mounts offer near-solid rigidity, keeping your engine stable under heavy loads while maintaining comfort in your driving experience.
- Proven in High-Performance Applications: From 1,000+ horsepower drag cars to circuit cars, Mad Polly mounts have proven themselves by eliminating engine and driveline flex. Experience improved throttle response, smoother gear shifts, enhanced traction, and precise steering control—giving you the edge on the track.
- Race-Proven Stability and Control: Prevents excess engine movement, leading to sharper throttle response, smoother gear shifts, and improved traction. In front-wheel-drive vehicles, this reduces wheel hop and axle tramp, enhancing grip and stability off the line and through corners.
- Built to Last: Our mounts are poured from premium, Australian-designed polyester-based polyurethane, crafted from locally sourced raw materials. This top-grade formulation is engineered to withstand the extreme demands of both above and underground mining in Australia. Unlike ether-based materials that can crumble and deteriorate over time, this polyester-based polyurethane resists direct sunlight, petroleum, and oil products. Tested in continuous Gold Coast sunlight for over 15 years, it endures the harshest conditions without degradation, providing unmatched resilience and longevity.

🔧 DIY-Friendly Installation
Mad Polly’s Competition Race mounts are designed with the DIY enthusiast in mind. No hydraulic press is needed! To install, remove the OEM rubber from your existing mount casing while leaving the metal ring pressed in place. This design makes installation accessible to those without advanced tools, though some effort may be required to extract the rubber inserts.
🔧 Installation Information
Mad Polly mounts are designed with a slightly larger crush tube hole to allow easier alignment during installation. Due to the design involving the removal of the OEM rubber inserts (while retaining the original metal casing), fitment may vary slightly across different vehicles. Once bolted down, the clamping force secures the mount tightly, ensuring stability under extreme torque.
⚠️ Important Installation Notes
- Check Dimensions Before Ordering: Vehicle variations can affect fitment. Please verify dimensions below before ordering to ensure compatibility.
- If you are unsure how to do this it would be recommended to give it to your mechanic for them to do.
- New crush tubes are supplied with the poly inserts, the OEM crush tubes are not used.
Remeber to LEAVE THE INNER METAL RING IN
Simply heat up or cut out the original rubber, knock out the OEM rubber including the crush tube or cylinder, then replace it with our Mad Polly high performance insert.
