Conversion outdrive cups for the 22SR diff allows you to use the diff with popular MIP pucks and roller bones.
Replaces the stock plastic outdrives of the 22SR diff with heavy duty hard anodized 7075 cups for longer lasting stock racing performance when combined with MIP pucks or rollers (not included).
Note- the stock TLR22 bones are not compatible. 67mm length puck bones are recommended for the 22 4.0.
