Transmission Mount Flex Disc for BMW E30 E46 E36 E53 Z4 with Aluminum Polyurethane

Upgrade or replace your BMW’s driveline with this robust BMW Transmission Mount Flex Disc, designed for E30, E46, E36, E53 and Z4 applications. Built from a rigid combination of T6061 aluminum and 85A polyurethane, it delivers improved stiffness, better torque handling, and lasting durability compared with softer OEM components. The aluminum frame features hard anodizing for enhanced corrosion resistance, while the polyurethane bushings absorb vibrations and reduce driveline noise for a smoother, more confident drive.

This large 96mm flex disc with 12mm bolt holes is engineered to replace OEM part # 26117511454. It’s a rebuildable design, so you can extend service life with our flex disk rebuild kits. Important installation note: this part is very rigid and requires precise installation. The driveline must be properly aligned and all driveline components must be in good condition and properly balanced to ensure optimal performance and longevity.
