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.
