The direct bolt-in 1000HP axles are now available for the 1999-2005 Golf / GTI / Jetta / Beetle (VR6 / 1.8T) 5-speed manual (except 337 chassis). These axles feature a direct fit outer CV that will fit the factory hubs and is made from a special proprietary material that is designed for high horsepower applications. The axle bars are made from a high grade aircraft quality material that is much more torsional than the factory axle bars, allowing them to twist and absorb shock loads, with a spline size that is significantly larger than stock. The inner CV is a108mm Porsche-type CV, with our proprietary cage and race set that is used on our highest level axles. The axles will also include a conversion plate to change the bolt pattern over to fit the factory stubs (if you are needing a high HP set and want stubs the Diff will have to changed back to the snap ring style ends)
