Description

Suitable for both automatic and manual transmission MINI F series models the Powerflex Gearbox Mounting Bush Insert is a simple yet highly effective upgrade designed to reinforce the original gearbox mount and reduce unwanted drivetrain movement. Manufactured from Powerflex's Yellow 70A durometer polyurethane, the insert fits into the voids of the factory gearbox mount, increasing stiffness without the cost or complexity of replacing the entire mounting assembly.

As engine torque increases through ECU tuning, upgraded turbochargers or other performance modifications, the forces acting on the engine and gearbox mounts rise significantly. The standard rubber mounts are designed to prioritise refinement and comfort, but under increased load they can allow excessive drivetrain movement, leading to wheel hop, less precise gear changes and a less direct driving experience.

By filling the voids within the original mount, the Powerflex insert helps limit excessive movement of the gearbox and engine assembly during acceleration, gear changes and cornering. The result is improved drivetrain stability, sharper throttle response and more consistent power delivery to the road.

This upgrade is particularly recommended for tuned vehicles producing increased torque, as well as drivers who enjoy spirited road driving or track day use. It offers an affordable way to improve drivetrain control whilst retaining the original mount and maintaining excellent everyday usability.

Key Benefits

  • Reinforces the factory gearbox mount
  • Reduces excessive engine and gearbox movement Improves drivetrain stability under acceleration
  • Enhances gear shift feel and precision Improves throttle response and power transfer Ideal for tuned and high torque applications 
  • Cost effective alternative to replacing the complete mount

Manufactured from Powerflex Yellow 70A polyurethane, this insert provides an excellent balance between performance and refinement, making it one of the most popular upgrades for enthusiasts looking to improve the feel and responsiveness of their MINI.

Please note: This insert is designed to fit the original gearbox mount and is not compatible with the MINI 306 JCW models including the GP3 model.
