Powerflex Road Series PFF5-7001 Front Radius Arm to Chassis Bush for BMW 7 Series F01 F02 F03 F04 & 5 Series GT F07 (Thrust/Tension Strut Bush, Poly) - Replaces OEM 31126775145 - Also Fits Rolls-Royce Ghost/Dawn/Wraith

PFF5-7001 Front Lower Arm Bush Upgrade - BMW F01 F02 F03 F04, F07 GT - Also suits Rolls-Royce Ghost, Dawn, Wraith

Transform steering precision and braking stability with the Powerflex PFF5-7001 polyurethane front lower control arm rear bush. This direct-fit mount replaces the factory rubber compliance bush at the chassis end of the front caster arm, giving your big BMW or Rolls-Royce sharper turn-in, reduced geometry change under load and a more planted feel on the road.

We have installed these at MJ Modifications and the results speak for themselves. Customers report tighter steering, better stability under hard braking and a noticeable reduction in vagueness from the front end without ruining ride comfort. It is an ideal road and fast-road upgrade for owners who want long-lasting performance from a premium bushing solution.

Key benefits

• Improves steering accuracy and on-centre feel
• Reduces arm deflection for consistent alignment and tyre wear

Why this upgrade

Big executive platforms benefit massively from a stiffer, high-quality front arm mounting. By controlling unwanted movement at the rear pivot of the front lower arm, this bush keeps caster and toe more stable, helping your alignment settings do their job. The result is cleaner feedback, better road holding and confidence-inspiring stability at speed.
