Powerflex PFF5-4631 Front Linkage/Shift Arm Oval Bush – Polyurethane Shifter/Selector Rod/Transmission Linkage Bushing Insert – BMW Z4 E89 2009-On – Gear Change Upgrade – Replaces BMW 25117507695

PFF5-4631 Front Linkage Bush for BMW Z4 E89 2009 onwards

Transform the way your Z4 changes gear with this high performance urethane front linkage insert. By replacing the soft, ageing factory component, this upgrade tightens the connection between the gear lever and the gearbox for a more direct, confidence‑inspiring shift. Expect reduced slop, cleaner engagement and a more connected driving feel on road or on track.

Built from an advanced polyurethane compound, it resists oil, heat and road grime far better than standard rubber. The result is consistent performance and long service life, making it a smart driveline enhancement for spirited fast road use, weekend blasts and track days alike.

Key reasons to choose this upgrade

• Crisper gear changes with noticeably less play in the selector linkage
• Improved shift precision for a tighter, more positive gate
• Durable poly compound that outlasts OE rubber in demanding conditions
• Stable, repeatable performance thanks to reduced deflection
• Great value upgrade that you fit once and enjoy for years
• Manufacturer lifetime warranty for peace of mind
