Get the best performance with a JB Performance fully rebuilt Kawasaki Ultra 300, 300X, 310/X/R/LX/SE Supercharger. READY TO SHIP!
Kawasaki OEM part when new# 15051-3704
Features the following improvements:
- JB Performance Supercharger oil with Tribodyn. Oil temperatures will run 40 to 90 degrees cooler than OEM oil.
- Fluro-rubber orings in water passages won’t shrink like the original buna, causing water to enter the gear case.
- Full rebuild with SKF and INA bearings, flouro-rubber front seal, dual lip PTFE rotor seals.
- Lizard Skin Ceramic coated supercharger rotors reduce heat soak and add more boost with tighter tolerances between case and rotors. Ceramic will not flake off and plug your intercooler like the factory rotor coating. Compatible with nitrous, methanol, and alcohol.
- New marine grade stainless steel washers and blue zinc pulley bolts (hardened). Stainless steel pulley bolts are not strong enough for shear force.
- 2x Brass coolant line fittings- installed.
Reduce the cost to purchase by trading in your old supercharger before or after purchase. Requires a full inspection of the old unit to determine price. Must be rebuildable with bearings seals, and any rotor coating. Any other damage is pro-rated. Trade in average is $0 to $800.
