Powerflex PFR5-721 Rear Subframe/Cradle/Carrier Mount Insert Kit Bushes/Bushings for BMW E60 E61 5 Series & E63 E64 6 Series (2003-2010) incl xDrive AWD – Polyurethane Road Series – Replaces OE 33316770826

Powerflex PFR5-721 Rear Carrier Mount Insert Bushings for BMW E60 E61 E63 E64

Transform the way your BMW drives with the Powerflex PFR5-721 rear carrier insert bushings. Designed for the E60 and E61 5 Series, including AWD xDrive, and the E63 and E64 6 Series from 2003 to 2010, these urethane inserts reinforce the factory rear cradle mounts to deliver a planted, confidence-inspiring back end without harshness. Perfect for enthusiastic road use and fast-road setups where control and comfort both matter.

Why this upgrade is a game changer

• Locks down unwanted movement in the rear axle carrier for crisp, predictable handling
• Improves traction out of corners and reduces axle tramp under acceleration
• Sharper turn-in, better stability under braking and more consistent geometry
• Road Series polyurethane compound resists wear and heat for long-term durability
• Helps reduce uneven tyre wear and offers excellent value over time
• Minimal change to cabin refinement compared with tired rubber mounts

How it works

This is an insert kit that presses into the cavities of the original rear sub-frame mountings, stiffening the OE bushings to curb flex and movement. It is a smart solution when you want extra control without switching to full solid or complete replacement bushes.

If you need a full replacement bushing assembly, see part PFR5-722.
