034Motorsport Street Density Transmission/Gearbox Support Mount Bush/Bushing 60A Rubber for BMW E36 E46 E87 E90-E93 E39 Z3 Z4 | Uprated Trans Mount for 1/3/5 Series (130i 325i 530i) | Manual Getrag/ZF | Voidless OE+ Replacement | 034-509-4050-SD

034Motorsport Street Density Gearbox Support Mount for BMW

Tighten up gearchanges, cut unwanted driveline movement and keep cabin comfort intact. This uprated 034Motorsport Street Density gearbox support uses 60A vulcanised rubber in a solid, voidless design that replaces the soft OE item. Expect a more precise shift feel, improved power delivery and greater confidence under acceleration, braking and cornering without the harshness of many polyurethane alternatives.

Ideal for daily drivers, fast-road builds and the occasional track day, this OE-style upgrade is a direct swap for the factory mounting on popular BMW platforms. We run these mounts on our own cars and customer feedback has been consistently positive for sharper gear engagement and reduced drivetrain lash.

Why this mount works

• 60A high-durometer rubber for a firmer, more controlled gearbox location
• Void-free, fluid-free construction helps prevent collapse and premature sagging
• Cleaner gear selection and less gear lever movement under load
• Direct replacement fitment with OE-style hardware locations
• Rubber isolates noise and vibration better than many poly mounts while still giving a sportier feel
• Sold individually. Most vehicles require 2 supports

Street-friendly precision

The upgraded rubber compound resists packing out and maintains its stiffness over time. You get a connected driving experience and a more stable powertrain with NVH levels close to stock, making it a smart OE-plus solution for manual BMWs that see real-world use.

Rubber vs polyurethane

Rubber excels at damping in tension, compression and shear, which is crucial for mounts. Polyurethane relies more on compression and can ovalise or wear in high-load applications. This Street Density rubber mount delivers lasting performance, consistent isolation and less buzz through the cabin.
