This is our Level 3 500HP Axle/Hub system for the 88-92 VW Golf / GTI / Jetta 5-Speed. This system starts with a set of high grade aircraft quality axle bars with our unique double temper and heat treat that makes them stronger and significantly more torsional than the factory axle bars. The inner CV features a proprietary cage and race set and the outer CV is about 40% larger than the stock VW one and we also include a custom hub to accomodate the larger outer CV spline. This kit includes both axles, hubs and extended 12mm ARP wheel studs. This system can also be made in custom sizes for hybrid applications also. Rated to 500HP with a 1-year warranty.
