500 HP Axle/Hub Combo
The 500 HP drive shafts use a much larger diameter CV. These units are heat-treated, liquid salt bath quenched and double tempered (ion nitriding process ) to give the axle stubs extra strength while maintaining torsional twist to resist heavy-duty shock loads. They are also supplied with our specially redesigned center shafts that eliminate instant breakage during high RPM launches. The 500 HP sets come complete with two new axle hubs to accommodate the larger diameter stubs. These units are assembled with extreme high-temperature CV grease and quiality.

500+ HP Extreme Axle/Hub Combo Race Shafts
These Race Shafts are the meanest sets TCI has ever made! Intended for the record breaker, not only are the included new hubs oversized by 0.180'', but these shafts are also made from 300M chromemoly steel, the strongest alloy available for this application. Combined with our reengineereed center shaft that is 0.150'' diameter larger than stock at the internal clip groove and assembled with special hard CV boots, this extreme combination will handle over 500 HP and will keep you on the track, not in the pits!
