Direct-fit Powerflex PFR5-1423 polyurethane insert for the rear subframe bush (OEM 33316784940) on BMW X5 E70, F15 and X6 E71, F16. Not for X5M/X6M.

Slips into your existing bush to reduce deflection - sharpening turn-in, tightening rear-end response under braking and acceleration, and improving steering feedback. A fast-road or track-day upgrade that stays compliant enough for daily use.

• Installs in minutes with basic tools - no machining, welding or subframe removal
• High-durometer polyurethane: durable, consistent, road legal
• Delivers most of the handling gain of full bush replacement at a fraction of the cost and effort
