034Motorsport Street Density RH/Right-Hand Engine Mount (Passenger/Offside Motor Mount) for BMW N54 N55 1M, 135i, 335i, X1, Z4 E82 E88 E90 E91 E92 E93 E84 E

Uprated Right-Hand Engine Mount for BMW 1 Series, 3 Series, X1 and Z4

Give your turbocharged straight-six the support it deserves. This offside RH engine mount from 034Motorsport’s Density Line replaces the factory insulator with a high-durometer, void-free, solid-filled rubber mount designed for sharper response and long-term reliability. It is a direct-fit right-side unit for N54 and N55 applications on E8x, E9x, E84 and E89 models.

We run these mounts on our own builds and our customers consistently report crisper shifts, more immediate throttle response and far less drivetrain movement without unwanted noise, vibration or harshness. If you’re chasing a smooth daily drive with confident performance on road or track, this is the upgrade.

Why choose this RH engine support

• 50 durometer rubber, solid-filled and void-free for a noticeable increase in stiffness over stock
• Reduces engine rock under load to help cut wheel hop and improve traction
• Sharpened shift feel and cleaner power delivery
• Cast aluminium body built using OE-grade production methods
• Fluid-free design eliminates the risk of leakage and collapse common with ageing hydro mounts
• Complete drop-in replacement of the factory right-hand mount

High-durometer rubber advantages

Unlike typical polyurethane inserts, vulcanised rubber excels in tension, compression and shear. It resists packing and premature wear, maintains damping performance over time and keeps NVH in check. The result is a durable mount upgrade that feels tight and refined, not harsh.
