Did you know that the Polaris RZR Pro Turbo has new clutches and requires different components than the original RZR Turbo? This is the Venom Performance Adjustable Weight Set that allows you to fine tune your clutches for peak performance. Tires and wheels, performance upgrades to the engine, and different kind of riding require adjustment to the clutches to get the optimum in performance and belt life. These weights are designed by the same people that help to design the factory clutch so the fit and operation are perfect. These last much longer than the magnet style weights found in competing products. Capable of working with most setups, stock to highly modified.
