Camso 4S1 Generations

We have been selling Camso UTV track systems for about fifteen years, and in that time the system has been through several real changes — not just a new name on the sticker. We have also seen which parts held up, which parts caused problems, and how Camoplast, and then Camso, fixed them. If you are looking at a used set, trying to identify an older system, or wondering why the current 4S1 has the reputation it does, that history is the fastest way to understand what you are actually looking at.

The three generations

Three systems, roughly fifteen years, one evolving design. The two things that changed most are the two things that cost the most when they go wrong: the main drive hub and the bogey wheels.

2011–2014: Camoplast Tatou T4S UTV (6822)

The early version of what eventually became the 4S1 was built by Camoplast and sold as the Tatou T4S UTV. These systems can generally be identified by a serial number beginning 6822. It was the first generation of this style of UTV track system — a good concept, and after selling and servicing them we could see exactly where it needed work.

The biggest issue was the main drive hub. The 6822 used a two-bearing design, and those bearings were not running in an oil bath. Camoplast tracked warranty claims closely, and failure in that two-bearing main hub assembly was one of the main problems their own data identified.

The other weak spot was the grey plastic bogey wheels, which wore considerably faster than the wheels that replaced them. None of this made the system unusable — plenty of 6822s are still working — but there was real room for improvement, and Camoplast took it.

2014: the 6722 series and the hub fix

Around 2014, Camoplast — which became Camso the following year — introduced an updated system identified by the 6722 serial series. The important change was the main hub.

The two-bearing design was replaced with a three-bearing main hub assembly, and, just as importantly, the new hub was oil bathed. The extra bearing spread the load; the oil kept the bearings cooler and cleaner. Together they made the hub substantially stronger and noticeably extended bearing life. This is the single biggest durability change in the whole lineage.

The 6722 generation also got the newer, smaller black bogey wheels. In our experience those are much more durable than the grey wheels they replaced.

2016: the Camso 4S1 arrives

In 2016 Camso introduced the Camso UTV 4S1. It kept the best part of the previous generation — the three-bearing, oil-bathed main hub — and substantially redesigned the track frame and the way the bogey wheels mount to it.

On the earlier systems the bogey wheels were mounted to the frame on a steel shaft. That becomes a limitation on side hills, because the wheels have very little ability to follow the angle and contour of the ground underneath them.

The 4S1 changed that. The smaller bogey wheels attach to the frame through rubber-mounted supports, so the bogey assemblies can pivot slightly up and down instead of staying completely rigid. In actual use that means a smoother ride and more even track contact and ground pressure over uneven terrain and side hills — which is also easier on the track itself.

Why the 4S1 earned its reputation

After selling these systems for this long, we consider the 4S1 an extremely durable track system — and the reason is the history above. Camso did not simply rename the product every few years. They learned from the failures in the earlier systems and redesigned the parts that needed it. The progression was essentially Tatou T4S (6822) → updated 6722 → Camso 4S1.

The stronger three-bearing oil-bath hub, the better bogey wheels, and the rubber-mounted bogey design are what turned this into the dependable system owners know today. For the majority of conventional ATVs and UTVs, the 4S1 is still an excellent choice.

Heavier UTVs led to the Camso ENDUR

UTVs have changed a lot since those early Camoplast systems. Today's machines are larger, more powerful, and considerably heavier. That is why Camso developed the heavier-duty Camso UTV ENDUR for selected vehicles — a more commercially built system for applications where the weight and output of a modern UTV ask more than the 4S1 was designed to give.

Current ENDUR applications include selected models such as:

• 2026 Polaris Ranger XD 1500
• 2024–2026 Polaris Xpedition XP / ADV
• 2021–2026 Polaris Ranger XP 1000
• CFMOTO UForce U10 Pro

Fitment changes by model and production year, so verify the exact year, make and model before ordering rather than assuming by analogy.

ENDUR vs 4S1

The question we are starting to get is what the difference actually is. The easiest way to understand it is to see the two side by side — if you have only seen pictures of the ENDUR online, the scale of it does not come through.

The ENDUR should not be read as a replacement for every 4S1. It was developed for specific newer, heavier UTV applications where a more commercially built system makes sense. For the full breakdown — where to spend up and where to save — see Camso ENDUR vs 4S1.

Buying a used set? Serial numbers matter

The thing we most want used buyers to take away: two sets of Camso tracks that look similar in photos can be very different inside. Before money changes hands, check the serial numbers.

Knowing whether you are looking at a 6822, a 6722 or a current 4S1 tells you which hub is in it, which bogey wheels it has, and what generation of frame you are buying. It also makes a large difference when ordering replacement parts, and a larger one when converting a used system from one UTV to another.

On a current 4S1 the serial is stamped on the track system frame and marked on the rubber track itself. Photograph all four, and get the year, make and model of the UTV they came off as well as the one they are going on.

Then measure before you buy, if you can. The published wear limits tell you whether “only a few hours on it” means the wheels, guides and sprockets are near the end of their service life — which is the difference between a good used buy and a cheap system that needs a thousand dollars of consumables.

What we can help with

ATVTracks.net has been selling Camso track systems and replacement parts for about fifteen years. That includes:

• New Camso 4S1 track systems
• Camso ENDUR track systems
• Replacement tracks and parts
• Bearings
• Bogey wheels
• Sprockets and hubs
• Transfer kits
• Identifying older Camso and Camoplast systems
• Converting a used track system from one UTV to another

If you are not sure which system you have, or which one fits your machine, have the track serial numbers and your UTV's year, make and model in front of you when you get in touch — it saves a lot of back-and-forth and prevents ordering the wrong components. You can reach the fitment desk at 866-243-8359, or through our contact page.
