Powerflex PFF5-4631 Gear Selector Arm Bush Oval for BMW M4 F82 F83

Sharpen your BMW M4 gear selection with the Powerflex PFF5-4631 Oval Gear Selector Arm Bush. This precision-engineered urethane insert replaces the tired OE rubber bush to cut unwanted movement in the change linkage, giving a tighter, more accurate shift feel on fast road and track while remaining perfectly usable every day.

If your lever feels vague or notchy, this simple upgrade helps remove slop and play from the selector mechanism, improving engagement and consistency. Built from long-lasting polyurethane that resists oil, heat and road grime, it is a durable, fit-and-forget solution that keeps the transmission linkage stable under load.

Why this upgrade works

Factory rubber bushes allow the selector arm to move, which blurs the connection between the lever and the gearbox. The Powerflex PFF5-4631 uses performance-grade polyurethane to control that movement, keeping the selector rod located so your input translates into a precise gear change. Expect a firmer, crisper action and improved confidence when pushing on.
