Powerflex PFF5-4631 Shift Arm Front Bush Oval Polyurethane for BMW 6 Series E63/E64 (2003-2010) Gear Linkage Shifter Bush OE 25117507695

PFF5-4631 Selector Arm Front Bushing for BMW 6 Series E63 E64 2003 to 2010

Transform your gear change feel with the Powerflex PFF5-4631 selector arm front bushing. This precision polyurethane insert replaces the soft OE item that lets the transmission linkage flex, removing slack and tightening up the gear lever action. Expect a cleaner, more positive engagement and a more connected drive every time you shift.

• Crisper, more accurate gear selection with reduced play in the change linkage
• Polyurethane construction resists oil, heat and road grime far better than factory rubber
• Direct-fit replacement for the front mount on the selector arm, engineered for E63 and E64 platforms
• Consistent performance that does not perish like standard bushes
• Backed by the Powerflex Lifetime Warranty for peace of mind

We have installed this part in-house for customers and on our own builds, and the feedback is the same every time: tighter shift feel, reduced wobble at the gearstick and a more precise transmission response. If you want a sharper, more engaging drive, this upgrade delivers.

Why upgrade this location

The front mount on the selector arm is a known source of slop in the gear change mechanism. Replacing the ageing rubber with a Powerflex polyurethane insert controls unwanted movement in the linkage, improving shift precision on fast road use and everyday driving alike.
