High Performance Applications Offen Reveal Problems With Stock Power Train Components That Were Never Anticipated by The Designers. One Such Problem is The Tendancy of the Stock Inner Primary Bearing Race On Late Model Big Twins to Shift On The Transmission Main Shaft Under High Torque Loads. This "Walking" of the Race Can results in the destruction of the transmission Main Shaft Seal, and Ultimately The Main Shaft, Output Gear and Output Gear Bearing. Costly Repairs and Annoying Down Time. A Unique Modification to The Design of The Main Shaft Inner Primary Bearing Race, Positive P Prevents It From "Walking" Into The Main Shaft Seal and Output Gear. The S&S Bearing Race Features An extra step on the Inside Diameter that acts as a stop on the Transmission Main Shaft. When the race is pressed on the Shaft, The Step Will Not Allow The Race To Moveard Toward The Main Shaft Seal. Can be retrophyted to stock and Aftermarket transmissions.
