Powerflex Black Series 95A Engine/Motor Mount Insert Kit – BMW X5 G05 2018+ Polyurethane Mount Support Bushings, Drivetrain Stabiliser, Torque Mount Reinforcement | Fast Road & Track | PFF5-4020BLK

Polyurethane motor mount inserts for BMW G05 platform

Looking to tighten up drivetrain control on your 2018 onwards BMW G05 chassis without jumping to solid mounts or full replacements? This competition-grade polyurethane insert pair slots neatly into the voids of the factory engine supports to curb excessive movement under load. The result is crisper pedal response, cleaner upshifts, more immediate torque delivery and a more connected feel on fast road and track-day use.

We have installed these inserts on customer builds and our own development cars, and feedback has been consistently strong. Expect a noticeable improvement in stability when accelerating, shifting and transitioning on and off throttle.

Why enthusiasts choose this upgrade

• Limits engine rock for sharper drivability and improved shift precision
• Maximises power transfer by reducing compliance in the factory mounts
• More consistent handling balance during on and off throttle inputs
• Helps prolong the life of the original rubber mounts by supporting the voided sections
• Smart install design. Fits into the OE mount voids, so the mounts do not need to be removed
• Durable 95 Shore A material for serious performance use

What to expect

A modest increase in cabin vibration at idle is normal when stiffening the connection between the engine and subframe. The higher the hardness rating, the more vibration will be transmitted. Once moving, benefits far outweigh this trade-off for performance-focused drivers.
