4th wheel Kits for Rear Axle
From factory, Yamaha sleds have only 3 wheels on rear axle. This 3 wheel set up puts extra load on the solo wheel. If the solo wheel were to fail the sled is no longer rideable. By running a 4th wheel kit the load is evenly distributed on the rear axle, and should any one wheel fail the sled will still be rideable.
All 03-09 sleds, & all year Phazers & FX Nytro....$40 with new wheel and $30 with used wheel(if available)
All 2010-2015 Mono Shock II Apex and Vector......$50
SR Viper & Sidewinder models....$65
The viper 4th wheel kits utilize used standoffs from Yamaha Japan rear suspensions. The used standoffs allows us to keep the cost down on these kits. Kit includes includes (2) new wheels, (2) used standoffs and applicable hardware. This is a must have insurance policy as a tri hub failure will make a Viper & Sidewinder inoperable!
