S&S CYCLE Improved Inner Primary Bearing Race For 2008-Up HD® Big Twins - 560-0241

The tendency of the stock inner primary bearing race on late model big twins to shift on the transmission mainshaft under high torque loads, also known as “walking” of the race, can cause destruction of the transmission mainshaft seal, and ultimately the mainshaft seal, output gear and output gear bearing. The S&S inner primary bearing race features an extra step on the inside diameter that acts as a stop on the transmission mainshaft. When the race is pressed on to the shaft, the step will not allow the race to move inward toward the mainshaft seal. The improved S&S bearing race is a must for any high performance application.

• Eliminates bearing race movement that can cause costly damage to transmission seal and output bearing
• A must for high-performance applications
• Made in the U.S.A.
  
  NOTE: S&S Inner Primary Bearing Race PN 560-0241 fits big twin models with stock 6 speed Cruise Drive™ transmissions found in all 2008-2017 Twin Cam models and 2017-2020 M8 models.
