Inner Primary Bearing Upgrade Kit for 1990-2007 Big Twins

Includes one double row angular contact bearing, seal and snap ring.

Eliminates the seperate Inner bearing race has been used on Big Twins since 1985.
No more race walking on the mainshaft; if it walks inboard, it will damage the maindrive gear seal and cause a transmission oil leak; if it walks outboard, it will cause a primary oil leak.
This bearing presses into the inner primary cover and slides over the mainshaft. This makes doing transmission work easier as the race no longer needs to pulled off every time.

Fits:
1990-06 Softail
1990-Up FXR
1991-05 Dyna
1990-06 Touring
