Powerflex PFR5-4625 Rear Diff Front Bush Set for BMW E46 3 Series, Z4 E85/E86 & X3 E83 (xi/xd) | Polyurethane Polybush Final Drive Front Position Mount/Bushing Kit | Replaces 33176768655, 33176770788

Powerflex PFR5-4625 Polyurethane Front Position Rear Final Drive Bush Set

Transform rear-end precision on your BMW with the Powerflex PFR5-4625 front-position bushes for the rear final drive. This polyurethane mount set tightens up drivetrain control, curbs unwanted movement under load and delivers crisp, predictable handling for daily use and fast road driving. Ideal for tired factory rubber replacements, this upgrade restores confidence under acceleration and cornering while standing up to British roads and spirited use.

We run these in our own workshop builds and on customer cars, and the feedback is consistently positive. Expect a more planted rear axle, cleaner power delivery, better traction out of bends and a noticeable reduction in wheel hop and rear-end slop.

Why this upgrade works

• Locks the rear final drive in place for sharper throttle response and improved stability
• Keeps geometry consistent for more confidence mid-corner and on exit
• Durable polyurethane resists oil, heat and ageing far better than OEM rubber
• Great value long-term solution that helps protect surrounding components
• Road-friendly compound from Powerflex Road Series for everyday use and weekend blasts
