Powerflex PFF5-4631 Polyurethane Shifter Bushing - Front Oval Selector Arm Bush for BMW Z4 E89 (2009-on) - Gear Lever/Gearstick/Shift Linkage Carrier Mount Manual Gearbox Upgrade - Replaces OE 25117507695

Precision gear lever bush upgrade for BMW Z4 E89

Restore a tight, engaging gearchange on your BMW Z4 E89 with this front oval selector arm bush from Powerflex. By replacing the tired factory rubber insert with a performance polyurethane component, you stabilise the change lever support and take out excess freeplay for a cleaner, more positive shift across the gate. Perfect for spirited road driving and track days, and just as rewarding on everyday cars that deserve a more connected transmission feel.

We have installed this part for customers and the feedback has been outstanding. Expect a more defined gear pattern, improved precision when selecting gears and a reassuring, consistent shift feel that lasts.

Why this upgrade makes a difference

• Stiffens the selector carrier to minimise deflection under load and heat
• Reduces unwanted movement in the gear lever mechanism for cleaner engagement
• Resistant to oil, road grime and ageing, delivering long term performance
• Ideal for manual transmission Z4 E89 drivers who want sharper control
