Kawi Performance brand spring tensioner upgrade kit for Kawasaki jet ski, Ultra 300 & 310 model from 2011 to 2024

Reference: 30300-5025A



Direct replacement for factory bushings and rubber sleeves that weaken over time, causing tensioner misalignment and belt slippage.

Machined from marine-grade alloy, upgraded inserts with integrated seals and high-strength polymer sleeves provide superior support and durability.

Combined with the supplied O-rings, this kit minimizes the need for regular maintenance and improves reliability. Includes a specialized tool to facilitate the removal of factory bushings and original rubber sleeves.
