Usually, one of the first hard parts to fail when the HP begins to climb is the input shaft.
Any C4-equipped car with heavy modification needs an input shaft constructed of superior metal with proper heat-treating.
Made to fit post-1970 C4's, DYNAMIC's hardened shaft, especially when combined with their Solid-Strength Forward Drum, has proven itself countless times in street driven hot rods and competition vehicles as diverse as baja racers, and 1000+ HP Renegade Mustangs. This is the same shaft that is used at DYNAMIC in all their high performance C4's including the well known Mighty Mite lineup.
When just changing the shaft, no disassembly of the transmission is necessary.
