"Mainly use my ranger as a hunting buggy, slow driving in rough terrain. The clutch change made a complete difference. Instant clutch engagement. Rock crawling is a breeze, especially big loose rocks uphill. Installed an inline blower at the same time, before installing burning rubber and hot plastic is all you smelled. And yes it’s quieter. Had it since 2019 no issues."

"Date of purchase was approx. Oct. of 2014…. Very pleased with the clutch, I would not own a Ranger without one. I use mine for farm work and hunting in the mountains of SW Virginia. About 4 years ago, the clutch started dragging at idle just enough to make it hard to shift, called Duraclutch and they said for me to send it in and they rebuilt it free after over 5 years of use. Good people and great customer service."

This package has a retail value of over $400, for a limited time we are selling this package for just $249.99.

This new Calibration Upgrade Package will improve your overall riding experience. It especially improves the transition from clutch pack engagement to CVT low ratio. In most driving conditions it provides better fuel economy. Our testing shows longer clutch pack and belt life.

This GENERAL-1 Calibration Upgrade Package is for current owners of a 15-517 Duraclutch system up to 2/22/2021 with a  Secondary with part #10-158. Secondary Part Number is on a decal on the front &/or engraved on back outer edge of sheave.

This Upgrade Package will work for customers who have had the ECU flashed for false misfire codes. If your vehicle has the ECU re-flashed for RPM and horsepower changes or has other engine modifications, this Calibration Upgrade Package may not provide the improvements it was designed for.

Package includes a Primary Spring, a set of RG-75 Weights, Weight Pins and Nuts, Primary Decal, Primary Intake Filter and a new Belt. The under-hood filter provides clean air for CVT cooling improving durability in dusty riding conditions.
