EPI Performance Polaris Belly Buster Adjustable Clutch Weight (3 Pack)
Unlock the full potential of your Polaris machine with the EPI Performance Belly Buster Adjustable Clutch Weights. This 3-pack kit of the legendary Belly Buster design allows for dynamic clutch tuning, ensuring maximum power delivery and responsiveness across any terrain or modification level. Utilizing innovative rare-earth magnets, these weights offer up to 16 grams of total adjustability per arm across multiple positions, allowing you to easily add or subtract mass to raise or lower the engine's operating RPM.
This fine-tuning capability is essential for compensating for performance changes caused by installing oversized tires, riding at different elevations, or adding engine modifications like exhaust systems. Constructed from billet tool steel, these weights are meticulously heat-treated and plated for exceptional durability and extended life, far surpassing stock components. The EPI Belly Buster Adjustable Weights provide stronger low and mid-range power and deliver a more aggressive upshift and crisp backshift, making them the ultimate upgrade for Polaris owners serious about custom performance.
