Powerflex Transmission Mount Bushings! Powerflex polyurethane bushings are for the large gearbox mount on Gen 1 Mini Cooper and Cooper S. These fit into both sides of the large factory bushing to reinforce and stiffen it. This will reduce engine/transaxle movement. You will get more vibration back thru the car with this bushing, but all movement will be gone. This is a must for any track car!

Powerflex polyurethane bushings are designed to decrease the amount of deflection in your car's suspension for better handling, more driver feedback, and better tire wear. Powerflex uses premium polyurethane materials for minimal NVH (noise, vibration, harshness) and increased longevity over the stock rubber bushings. Bushings come in pre-determined durometers (measured hardness) from Powerflex to work best in each particular location. The street bushing will work best for mostly everyone. They have been spec'd by Powerflex to be the best durometers for your application and are 70A (Yellow), 80A (Purple), and 95A (Black).

Powerflex grease is supplied with every dynamic product. We suggest using only this grease for lubrication. Due to grooves and knurls cast into the material to hold the lubricant, bushings will rarely need re-lubing. We do not suggest using an "anti-seize" product for lubrication.

Want a stiffer bushing? Have a track car? Try "The Black Series." A new range of bushings developed for Race, Rally and Circuit use. The Powerflex Black Series bushings are manufactured using a 95 Shore A compound to provide maximum control of chassis geometry. Currently Special Order at this time.

Warranty: All Powerflex bushings are made in the UK and come with a 1 year, unlimited mile warranty.

    Better Shifting!

    Posted by Jacques Gordon on 8th Nov 2022

    The trans mount bushings were easy to install once the mount is removed, and though there is just a bit of vibration at idle, the car is SO much easier to shift smoothly now. I highly recommend this product.
