Locked together sheave design Shock absorbing rubber backed graphite slide buttons

Rigid design to handle those high horsepower engines Clutch will accept the factory or aftermarket belt.

Shift roller for smooth and efficient performance

-"FACT", less friction in the clutch will transfer more power through the clutch. The QSC clutch design uses weights that pivot and apply pressure against a roller, creating an extremely efficient and responsive shift from "go" to top speed. Any primary clutch not equipped with a roller design these days is outdated technology! "FACT" The more efficient a clutch is the less power it needs from the engine to perform a shift cycle and it will react much faster to changing engine speeds, "RPM" -The fixed or locked together sheave design ELIMINATES one sheave from spinning faster than the other under a load. This prevents belt scrubbing, while providing significantly more belt pinch which is a must for high power machines with large tires. -The triple slide tower design. The slide buttons are rubber dampened, providing a cushion to reduce the shock impulses do to aggressive timing or the odd firing order of the Can-Am V-Twin engine. This will ensure reliability and reduce drive line shock especially on high horse power engines. -The 44mm one way bearing is the smallest in the business providing a super low starting gear ratio for slow speed technical riding or for the racer looking for that extra edge off the line. -The reinforced rigid design provides superior strength and light weight. At just over 8lbs the light weight design produces extremely quick revving and throttle response. The QSC clutch diameter is nearly identical to the factory clutch to maintain factory top speed." 80mph+ high gear. 42+mph low gear, "with the stock rev limiter and stock size tires" -All set ups under 3000' of elevation use the factory secondary clutch spring, "even for 32" tires" for low RPM cruising. This will help save on fuel and keep you on the trail longer.

The QuadShop Customs adjustable "Predator" weights are all this clutch needs to be arguably the best performing and most economical 3 weight aftermarket ATV clutch on the market. Depending on the primary spring, you can tune for any riding or racing type, engine size, factory or aftermarket secondary clutch, or elevation. The weights are cut with the aggressive QSC profile. This produces a hard hitting bottom end under heavy throttle, while maintaining a smooth engagement for the light throttle trail cruisers. The QSC adjustable "Predator" weights are the only ATV clutch weight to feature four adjustment points. One through the side just in front of the pin for engagement and slow speed full throttle tuning. Three on the bottom of the weight for RPM tuning at all speeds. The weight on the bottom method keeps the mass of the weight where it belongs. Some companies machine the whole side of the weight and then add weight back in, leaving mass voids and tuning voids between the fasteners. The mass on the bottom also keeps the weight from wanting to twist on the pin, keeping everything in balance and low on friction. The 4 point adjustment feature enables you to super load the base of the weights for tuning the bottom end on those high horsepower engines. The 3 under weight adjustment points allow for precise RPM tuning at any speed with the complete set of threaded multi weight adjustment fasteners for dialing in the entire "shift-out" RPM.

Aggressive QSC profile. "Cross Hole" for super loading your bottom end on modified engines. 3 adjustment points on the bottom for precise RPM tuning.

Weight is adjustable from 50 grams all the way to 72 grams. Multiple adjustment fasteners for countless adjustment options. (tire size, elevation, engine mods or aftermarket secondary clutches)
