A very common problem with the Yamaha YXZ 1000 is the weak OEM drive shaft spline coupler. Our solution is to Cryo Heat Treat and REM polish the coupler making it over 25% stronger than stock all while creating less friction which extends the life of your grease in the coupler. Pair this with our Heavy Duty Drive Shaft Dampener and our Pinion Bearing Support for the ultimate protection to keep you from being stranded! Go check yours today before it is too late!

Fitment: Fits all models and years YXZ 1000 including SS.

• Cryo Heat treated and rem polished splined coupler
