Rear Lower Arm Inner Bush Set – 14 mm Sleeve – BMW 6 Series E63/E64 (2003–2010) – Powerflex PFR5-711

Transform the back end of your BMW 6 Series with this uprated rear lower arm inner bush pair. Powerflex PFR5-711 replaces tired rubber with performance polyurethane for crisper steering response, a more planted feel and consistent geometry under load. Expect improved traction, better braking stability and greater confidence on fast road driving without the soggy behaviour of ageing OE bushes.

Made from high-quality polyurethane that resists oil, salt and heat, these bushes deliver long-term durability and a precise, direct chassis feel. Backed by the Powerflex Lifetime Warranty, they are a fit-and-forget upgrade that tackles unwanted flex and helps your tyres maintain optimal contact with the tarmac.
