8MM BOLT-IN ENCLOSED PRIMARY BELT DRIVE KITS WITH CLUTCH FOR BIG TWIN 4 & 5 SPEED MODELS

Weight: 18.43
Chuck the chain and bolt in the belt for a smoother ride with this 8mm Enclosed Primary Belt Drive Kit from Belt Drive Limited. Designed for use without modification to the inner primary cover, these bolt-in kits feature cylindrical shaped, replaceable round clutch dogs which can withstand 1200 pounds of torque. The inner stressproof steel hub is designed to move the weight of the clutch basket inward over the mainshaft 1" which distributes the weight more evenly on the mainshaft. To ensure a low rotating weight and provide long life, both the front and rear pulleys are made of lightweight aluminum and are hard anodized. Rounding out these kits are a set of Kevlar^® clutch plates that provide 60% more surface area than the OE clutch and a Kevlar^® belt for positive performance. If more clutch plate pressure is needed, the pressure plate is designed to accept up to 6 more clutch springs if required. Each kit includes a sealed primary bearing (except kit 77028). A primary bearing seal is also included for those who don't want to change the OEM non-sealed style bearing. Change over today for a smoother, quieter ride. For replacement parts, see the drive train section for clutch or starter ring gear.

Note: Due to the numerous variables of misalignment and improper tensioning upon installation, there is no warranty on belts.

Note: No modification is required to the inner primary for installation.
