Powerflex Black Series Rear Diff Front Mount Bush Kit for BMW M4 G82/G83 (2020+) – Performance Polyurethane Differential Mount Bushings – OE 33118090205 Upgrade – PFR5-4024BLK

Part number: PFR5-4024BLK

Unlock sharper traction and rear-end stability on your BMW M4 with this motorsport-grade rear differential front mount bushing kit for the G82 and G83 platforms from 2020 onwards. Built for serious fast-road, track day and drag strip use, this Black Series upgrade tightens up the driveline to deliver cleaner launches, more consistent power delivery and confident corner-exit grip.

Engineered from our signature Black 95A hardness urethane paired with black anodised 2011-T6 aluminium sleeves, this complete assembly replaces the soft factory mounts to curb unwanted movement in the rear drivetrain. The result is reduced axle tramp and wheel hop under hard acceleration, improved throttle response and a more connected, predictable rear axle on road and circuit.

• Designed for BMW M4 G82 coupe and G83 convertible, 2020 on
• Black Series 95A performance poly construction with anodised 2011-T6 aluminium inserts
• Controls driveline wind-up for crisper launches and stronger traction
• Helps minimise wheel hop and axle tramp during aggressive starts
• Complete replacement kit for the front mounts of the rear differential
• Direct swap for OE reference 33118090205
• Pack contents: 4 bushes
• Diagram reference: 21

We run this setup on our own builds and customer cars with excellent feedback on rear-end control, shift feel and overall stability. If you are chasing lap-time consistency, looking to make the most of launch control or simply want a more precise, connected drive, this is the diff mount upgrade that delivers.
