Powerflex PFR5-721 Rear Subframe Rear Mounting Insert Polyurethane Bush Kit (2 Inserts) for BMW 5 Series E60 E61 xDrive OE 33316770826

PFR5-721 Rear Crossmember Rear Mount Insert Kit for BMW E60 E61 xDrive - OE 33316770826

Sharpen the back end of your BMW with this PFR5-721 rear crossmember rear mount insert kit. Designed for the E60 and E61 xDrive platform, this tough urethane insert pair tightens up the rear axle carrier, curbs unwanted movement and keeps suspension geometry consistent under load. The result is crisper turn-in, better traction out of bends and a more planted, confidence-inspiring drive on road or fast road.

Why upgrade

• Reduces sub-frame shift for cleaner alignment control
• Improves stability under braking and mid-corner bumps
• Helps minimise wheel hop and axle tramp on hard launches
• More precise rear-end response without a harsh ride
• Durable performance compound with excellent NVH manners
• Backed by a Lifetime Warranty from the manufacturer

How it works

This insert cleverly fills the voids in the factory rubber rear mount on the rear axle carrier. By supporting the OEM bush rather than replacing it, it limits deflection where it matters most, keeping the cradle located and letting your dampers, springs and tyres do their best work. Expect tighter chassis control and more consistent feedback from your E60 E61 xDrive.
