Powerflex PFF5-4631 Shift Arm Front Bush Oval for BMW 1 Series E81 E82 E87 E88 Polyurethane Shifter/Gear Linkage Bushing (OE 25117507695)

Sharper, more positive gear changes for BMW 1 Series E8x

Restore precision to your manual gearbox with the Powerflex PFF5-4631 selector bush. This polyurethane insert replaces the factory rubber at the front of the selector arm, tightening the gear lever mechanism and giving crisper engagement, reduced slop and a more connected shift feel on BMW 1 Series E81, E82, E87 and E88 models.

If your gear lever feels vague, spongy or inconsistent, this upgrade delivers a direct, confidence-inspiring action ideal for daily driving, spirited road use and track days. It is a simple, high-value drivetrain refinement that enhances the feel of every shift.

Key reasons to choose this upgrade

• Reduces free play in the selector mechanism for a tighter, more accurate throw
• Polyurethane construction resists oil, heat and road grime far better than OE rubber
• Consistent performance and durability for long-term reliability
• Direct replacement design for straightforward installation
• Backed by the Powerflex Lifetime Warranty
