These Primo belt drive kits for Evolution Big Twin and Twin Cam models have a different front and rear pulley combination which makes the use of idler or tensioner obsolete. This reduces customer cost and simplifies installation. Kits come with hard anodized front pulley, 1 3/4" wide 8mm pitch Aramid reinforced belt, complete Pro-Clutch clutch-pack and pressure plate assembly, as well as all necessary hardware and instructions.

IMPORTANT INFORMATION Due to the wide application and fitting variations of primary and final belts, Zodiac can not accept any claim for warranty as, no matter how long they have been used and no matter what the defect is, belts are not covered by any manufacturer warranty. To avoid any complications we suggest that belts should be installed by a qualified mechanic.
