Rear Axle Shaft Pair, 1200HP Rated

The Driveshaft Shop M5R1 is a pair of high-performance rear axle shafts engineered as an upgrade for the BMW F10 M5 and F06/F12/F13 M6. These axles are designed to withstand extreme power, boasting a rating of 1,200 horsepower and backed by a 1-year warranty. They serve as a direct replacement for the original equipment. Crafted from premium, aerospace-grade materials, these axles feature robust construction. The CV cage is made from durable chromoly, complemented by 36-spline shafts. Both inner and outer CV joints have been upgraded with custom race components. Notably, the chromoly 108mm inner CV is a direct fit for the stock unit and incorporates full aerospace-grade internals. Following assembly, the shafts undergo a tempering and shotpeening process to enhance strength. The outer CVs are protected by factory-style metal covers with double o-ring seals, ensuring longevity and performance. This kit includes both the left and right rear axles, but requires customers to supply two original axles as cores for the rebuilding process. These upgraded rear axles are compatible with the F10 M5 (2013-2016) and F06 M6 Gran Coupe, F13 M6 Coupe, and F12 M6 Convertible (2012-2017). They are also compatible with BMW rear axle part numbers 33212284115 and 33212284116. Specific BMW fitments include 5 Series F10/F11 (11-16) M5 (2013-2016) and 6 Series F12/F13 (12-18) M6 models.
