Turner Motorsport Performance Polyurethane Rear Shifter Bushing

Sharper gear changes for your BMW manual gearbox

Eliminate vague gear selection and tighten up your gearstick feel with this upgraded gear lever carrier bush and bracket assembly. The factory rubber insert softens and degrades, which adds play to the selector arm and makes it easier to miss gears. This urethane insert and CNC-machined aluminium mount restores precision, improves shift engagement and gives you the positive, connected change you want for fast road and track day driving, without making the cabin uncomfortably noisy.

Why enthusiasts choose this upgrade

• Noticeably tighter gear selection and improved gate definition
• Minimal increase in noise, vibration and harshness compared to stock
• Far greater durability than the soft OE rubber insert
• Consistent shift feel when hot or cold, daily or on circuit
• Works brilliantly alongside short-shift kits and factory gear levers

Engineering highlights

• CNC machined 6061-T6 aluminium bracket for strength and accuracy
• Type III black anodised finish for long-lasting corrosion resistance
• 70A urethane bushing for a firm, precise feel with everyday comfort
• Direct replacement for the original carrier bush assembly
• Made in America
