Product Details


This race flex disc is the small 78mm with 10mm bolt holes. It is commonly found on E30 vehicles with an automatic or manual transmission (excluding the M3 and 325E).

The Revshift race flex disc frame is made from 6061 aluminum with type III hard anodizing and utilizes high quality polyurethane bushings to maximize stiffness and strength while maintaining an appropriate amount of flex. 

FOR RACE USE ONLY! 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. The engine mounts, trans mounts, differential bushings, and subframe bushings must all be rigid to prevent driveline movement. We recommend a hardness of 95a or higher for these components. A new center support bearing and aft centering bushing are also recommended.


  • 6061 aluminum frame with type III hard anodizing
  • 95A polyurethane bushings
  • Replaces OEM part # 26111225624 (LK=78mm/10mm)
  • Rebuildable using one of our flex disk rebuild kits

Located in Detroit, Revshift is a performance engineering and manufacturing company committed to providing the highest quality performance products available. Every part is designed, engineered, and tested in their Motor City location using high-precision CNC equipment. Additionally, all polyurethane bushings are spec'd, processed, and molded in their own facility for guaranteed quality, reliability, and performance!
