Kawasaki Ultra 300 310 Pulley With Stainless Steel Idler
Regular price $550.00 Save $-550.00
Made of High Strength Billet Aluminum, with a military spec marine coating for optimal performance, belt wear, and corrosion resistance.
The pulley is designed to take anything you throw at it. Also acts as a heat sink at high RPM, removing frictional heat away from the belt.
Boost pressure is knocked up +3 PSI over what you have stock! Less than 100mm in diameter.
Must be used with 93 Octane gasoline minimally. Extra boost is within the safe limits of supercharger operation. The kit comes with a CNC Machined Lightweight High Strength Stealth Series Pulley, Idler installation tool, and a new steel Idler pulley that MUST be used with this pulley.
If you would like an ECU tune we have the tune that works with it.
