Powerflex PFR5-4614 Rear Axle Carrier Front Insert Set

Transform the way your BMW drives with this urethane rear cradle mount insert kit. Powerflex PFR5-4614 presses into the voids of the factory rubber mount to curb subframe movement, giving you sharper steering feel, improved traction and rock-steady stability under braking and cornering. A proven upgrade for fast road and track use that tightens up the rear of the car without making it harsh.

Why this upgrade works

  • Controls rear cradle deflection for predictable, confidence-inspiring handling
  • Keeps alignment true under load for even tyre wear and consistent geometry
  • Engineered polyurethane compound balances performance with low NVH
  • Resistant to oil, salt and ageing so it outlasts the standard rubber mount
  • Backed by the Powerflex Lifetime Warranty for long-term peace of mind

Compatibility

  • BMW 3 Series E46 all body styles including Touring estate, saloon, coupe and convertible, excluding M3
  • BMW X3 models
  • BMW Z4 models, excluding Z4M
  • Insert design fits the voids in the original equipment mount for a straightforward install

What you get

  • Pack contents: 2 inserts
  • Position: rear axle carrier front location
  • Diagram reference: 10
  • Part number: PFR5-4614
