This kit will improve the road holding of your car by ensuring that the wheels go up and down in the manner intended by Triumph, a situation not sustainable with rubber components. Installing SuperPro Polyurethane Bushings will give you:
• Constant steering geometry.
• More responsive steering.
• Increased tyre life.
• Longer service life to suspension components
• Better road handling & control and Alignment correction & stability.
All polyurethane components are SuperPro, The trunnion bushes are standard Nylon supplied with thrust washers, grease seals and shields. In the scheme of things, rubber will provide poor long term suspension stability, SuperPro polyurethane will be superior, and nylon, superior again. Therefore as Nylon is standard for TR4A-6 trunnion bushes, fitting polyurethane would be a retrograde step.
