Most people who buy a clutch kit for an RZR S are not chasing a dyno number. They are tired of the way the machine behaves in the slow stuff — the belt slipping and cooking on a rock crawl, the engine hunting for the right ratio on a long grade, the smell at the end of a hard section that tells you exactly how much money the belt has left. Those are clutch problems wearing a belt's clothes. The Duraclutch RXS Clutch System for the 2016-2026 Polaris RZR S 1000 replaces both halves of the drive instead of patching one, and it runs $1,499.00.
A system, not a kit of weights
Duraclutch describes this one simply: they paired their RXS EBS primary with a well-proven post tied secondary for the 2016-2026 RZR 1000 S, all models. That is the distinction that matters. A lot of what gets sold as a "clutch kit" is a set of weights, springs and a helix that you install into the clutch you already have — a tune of existing hardware. This is the hardware itself: a complete primary and a complete secondary, engineered to work as a pair.
Why that matters on a trail machine comes down to how a CVT behaves at low speed. The primary decides when the belt starts to grip and how it shifts out; the tied secondary controls how the belt is clamped on the driven side. Tune one in isolation and you usually fix one symptom and create another — better engagement but a belt that runs hot, or a cooler belt and a machine that bogs off idle. Matching the two from the start is the whole argument for buying a system.
The EBS part of the primary is the engine braking side of it, which is the half people notice on the way back down a hill rather than up it.
What comes in the box
- Duraclutch RXS primary clutch
- TEAM tied secondary clutch
- Belt
- Belt removal tool
- Primary and secondary hardware
- Blue Loctite
- Decals
- Easy-to-follow installation instructions
That is a complete job in one carton, and the two small items on that list are the ones that save a Saturday. The belt is included, which matters because a new clutch system and a tired old belt is a bad pairing — the belt is the consumable that the rest of the system is measured by, and you want a fresh one going in with new sheaves. The belt removal tool is the other one. Anyone who has tried to get a belt out of a tied secondary without the right tool knows why it is in the box.
Duraclutch calls it a direct bolt-on with easy installation, and the primary cover carries a Silver Storm carbon fiber pattern — purely cosmetic, but you will be looking at it every time the clutch cover comes off.
Fitment and part numbers
- 2016-2026 Polaris RZR 1000 S, all models
- Part numbers: 15-633, 15-634, 15-635
One clean eleven-year range covering every S 1000 variant, which is unusually simple as these things go. Write those part numbers down somewhere you will find them again — a note on your phone, or a label inside the clutch cover. Clutch components are the parts you end up cross-referencing years later when you want a replacement piece rather than another whole system.
Who it is for
This is for the RZR S owner who rides slow, technical ground, or who tows, or who has simply had enough of belts. A complete clutch system is a real expense next to a $160 belt, so the math only works if you are eating belts or if the way the machine drives at low speed genuinely bothers you. If you are, it works quickly — belts are not cheap, and neither is a ride that ends early.
What a clutch system will not do is cover for a dirty or worn clutch housing. Before you put new hardware in, blow the belt dust out of the cover, check that the clutch intake and exhaust ducts are sealed and clear, and look at the condition of the hoses and screens. Belt dust is abrasive and insulating at once, which is a bad combination, and fifteen hundred dollars of new clutch breathing through a plugged duct is a waste of good parts.
