"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."
