This is Level 5 Rear Axle/Hub system for the Evolution II / III / IV with factory Mechanical LSD (4-Lug hubs). These axles feature our heavy duty 32 spline center bars, up from the factory 30 spline, that are made from high grade aircraft quality material and are significantly more torsional than the factory bars, billet ball and cage inner CV's with an aerospace grade chromoly spline into the differential, an outer CV that is about 30% larger than stock with larger internals and we also include new hubs to accomodate the larger spline and ARP studs. ABS Rings are not included, can be added for an additional charge. Rated to 800HP with a 1-year warranty.
Please Note: These axles are for the Mechanical LSD ONLY, and will not fit the Viscous LSD.
The Viscous LSD left axle uses a long double spline into the differential, the Mechanical LSD axles use the same differential spline on both left and right axles.
