Powerflex Black Front Wishbone Rear Mount (Radius Arm) / Lower Control Arm to Chassis/Body Poly Bush Kit BMW X5 F15 (2013-on) & X6 F16 (2015-on), 95A Polyurethane, Uprated HD Suspension Bushings - PFF5-2402BLK - Replaces BMW 31126864000

BMW X5 F15 and X6 F16 Front Wishbone Rear Mount Poly Bush Kit

Transform the front end of your BMW SUV with a competition-grade polyurethane arm-to-body bush upgrade. This heavy-duty kit replaces the soft factory rubber at the rear mounting point of the front lower arms, delivering pin-sharp steering, stable geometry and repeatable handling under hard braking and cornering. Ideal for fast road, track days, time attack and spirited driving.

Built around a high-durometer 95A compound, these poly bushes dramatically reduce unwanted movement compared to OEM bushes. Expect crisper turn-in, better on-centre feel and improved tyre contact in demanding conditions, without the rapid wear associated with standard rubber.

Why this front suspension bush upgrade

• High-durometer polyurethane limits deflection at the front wishbone rear mount for precise alignment control
• Sharper steering response and more consistent geometry during heavy loads and repeated heat cycles
• Direct-fit replacement for the original arm-to-chassis mounting bush, no permanent modification required
• Durable, motorsport-focused construction designed for track-use abuse and fast road reliability
• Proven on our own builds with excellent feedback from MJ Modifications customers
