Powerflex PFF5-4631 Front Selector Arm Bush (Oval) for BMW 4 Series F32 F33 F36 xDrive AWD – Polyurethane Poly Bush Gear Lever/Shifter Linkage Insert – Manual Gearbox Shift Rod Bushing – Replaces OE 25117507695

PFF5-4631 Front Selector Arm Bushing – BMW 4 Series F32 F33 F36 xDrive

Eliminate sloppy gearchanges and transform shift accuracy with the PFF5-4631 front selector arm bushing. This high-grade polyurethane insert replaces the tired factory insert on xDrive BMW 4 Series F32, F33 and F36 models, tightening the transmission linkage for a cleaner, more positive gear engagement under road and fast-road use.

Built to outlast ageing rubber, this upgrade resists oil, heat and flex, reducing unwanted movement in the change rod. The result is a crisper, more consistent shift feel that inspires confidence every time you select a gear.

Why enthusiasts choose this upgrade

• Sharper gearchange with reduced play in the selector rod
• Polyurethane construction for durability and long service life
• Direct-fit oval insert for the correct xDrive application
• Ideal when refreshing gearbox linkage components or chasing a tighter shift
• Designed to handle spirited driving without the vagueness of soft OE rubber
