034 Motorsport Street Density Passenger Side Engine Mount - N54/N55

Uprate your BMW’s drivetrain control with this right-hand motor mount from 034Motorsport - the ideal offside engine support for N54 and N55 turbo models. If you are chasing tighter response, cleaner gear changes and fewer knocks under load, this street-focused upgrade delivers a noticeable improvement without turning your daily into a rattly track car.

Built for fast-road use and longevity, the Street Density compound uses a higher Shore rating rubber than the soft factory hydraulic unit. The bushing is solid rubber and non-hydraulic, so there is no fluid to leak and no voids to collapse over time. The result is far less powertrain movement when you accelerate, shift or corner hard, while keeping noise, vibration and harshness in check for comfortable commuting.

Why choose this uprated right-side motor mount

• Street Density compound - approximately 50A Shore for a firmer, more controlled feel versus OE
• Solid, non-hydraulic construction - no fluid, no voids, no messy failures
• Cast aluminium housing manufactured to OEM standards for excellent durability
• Reduces driveline play and engine rock under load for improved traction and stability
• Sharper gearchanges and more direct power delivery with minimal cabin NVH
• Direct-fit, bolt-on replacement for the original right-hand unit
• Sold individually - this listing is for the passenger side only

We have fitted these in-house on multiple N54 and N55 builds and the feedback is consistently positive - tighter throttle response, reduced axle tramp and a more connected feel without compromise on comfort. Customers running fast-road and occasional track days love the balance.
