Unlike other aftermarket mounts, the mounting plate and studs of our mounts have been Zinc-plated to prevent corrosion. Rogue Engineering Transmission Mounts are sold as a pair, and come with Grade 8 Zinc plated hardware. Rogue Engineering transmission mounts are designed with street comfort in mind while still reducing left and right movement of the transmission. By using a cylindrical shape instead of the factory hourglass like design and utilizing Neoprene rubber deflection can be significantly reduced, minimizing unwanted transmission movement while maintaining vibration dampening characteristics.

Ensure the longevity of your BMW's drivetrain with ECS Tuning's Magnetic Plugs. These plugs are meticulously engineered in-house to provide a perfect fit and feature a permanent magnet attached to the plug body. The magnet effectively attracts and captures tiny abrasive and ferrous metal particles, preventing their circulation through lubrication systems. Metal particles can accumulate due to various conditions such as normal wear, machining operations, casting flaws, and stress usage, leading to excessive wear of vital components. ECS Tuning's Magnetic Plugs help alleviate this concern by trapping these particles, thus safeguarding the internal components of your drivetrain. With a convenient 17mm hex head design, these plugs eliminate the need for special tools required for OEM plugs.

Key Benefits:

  • Removes abrasive metal particles from drivetrain fluid
  • Prevents excessive wear to internal components
  • Meticulously engineered for a perfect fit
  • Features a permanent magnet for efficient particle capture
  • Convenient 17mm hex head design for easy installation

Powerflex's new transfer case bushing insert is made from polyurethane and is designed to reinforce your OE rubber transfer case bushing. This helps to stiffen the bushing and limits excessive movement of the transfer case. This Street bushing is rated at 70A durometer, which is a bit stiffer than your OE bushing's rubber. This is perfect for someone who daily drives their BMW but still wants a bit extra support for their transfer case bushing. As this bushing is 70A durometer, a small amount of extra NVH can be expected.

A sloppy shifter is one of the common complaints of older BMWs. In addition to the shifter linkage the transmission mounts contribute to rough and clunky shifting. BMW transmission mounts are rubber and get softer over time. This allows the transmission to dance around which changes the geometry of the shift linkage and could make it harder to shift. These urethane transmission bushings are stiffer than the stock rubber mounts and won't let the transmission shift around as much. The round design also has more surface area than the stock mounts which helps spread the load. Because the urethane is stiffer, expect more vibration to make its way into the shift lever area. Engine motor mounts should also be considered as a cause for driveline vibration, transmission movement, and poor shifting. Consider replacing your motor mounts at the same time as your tranny mounts.

Price is for the pair of transmission mounts with hardware.
