Powerflex PFR5-419 Poly Subframe Bush Insert Kit – Rear Axle Carrier/Cradle Front Mount – BMW 1 Series E81 E82 E87 E88, 3 Series E90 E91 E92 E93 (E8x/E9x, incl xDrive AWD), X1 E84 – Polyurethane Suspension Bushes/Bushings – Replaces OE 33316758259

Powerflex PFR5-419 Poly Bush Inserts for Rear Axle Carrier Front Mounts

Sharpen the rear end of your BMW with Powerflex PFR5-419. These high-performance polyurethane inserts locate into the front positions of the rear axle carrier, cutting unwanted subframe movement to deliver tighter handling, stronger traction and a more planted, confidence-inspiring drive on road and fast road.

We use this exact kit on our own cars and customer builds at MJ Modifications, and the feedback is consistent: cleaner turn-in, better mid-corner stability and improved launch and braking control without the hassle of full bush replacement.

Why this upgrade makes a difference

• Reduces subframe deflection for precision steering feel and predictable chassis behaviour
• Improves traction out of bends and reduces wheel hop under hard acceleration
• Helps keep alignment settings more consistent for balanced tyre wear
• Durable polyurethane resists oil, salt and ageing far better than tired rubber
• Cost-effective performance upgrade vs. complete bush replacement
• Ideal for daily drivers, spirited B-road use and performance-focused builds
