UPR
5/8 Drive Shaft Spacer
This spacer eliminates the need to have custom shafts made for length deficiencies of 3/8'' to 5/8''. Greatly reduces the chance of slip yoke failure by maintaining proper engagement. This part was developed by UPR to fit C4 and Tremec transmissions. This spacer is made from billet aluminum for lower rotational mass. Kit includes grade 10.9 hardware.
