The TCI 500+ HP Racing Shafts are the meanest sets we make! Intended for the record breaker, not only are the included, new hubs oversized by 0.180" but these shafts are also made from 300M chrome moly steel, the strongest alloy available for this application. Combined with our reengineered 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.
