Camso X4S

The short version

The X4S is Camso’s cross-platform ATV system. It publishes two vehicle ratings where every other system in this category publishes one:

All-terrain 300 to 1000cc. Side-by-side 400 to 700cc.Camso, X4S, read 2026-09-26

That is the feature. A set of four X4S units is rated for a 300 to 1000cc quad and for a 400 to 700cc side-by-side, which means one design covers the two machines most working properties actually own. Camso says it fits 300+ ATV and 80+ UTV models.

Everything else about it is a T4S. Same belts, same lugs, same footprint, same frame material, same sprocket range, same offsets, same ground clearance, same warranty. Two figures move and one sentence changes, and they are covered below. If you own one quad and nothing else, read the fitment section before you assume that makes the X4S pointless — there is a specific class of quad where it is the system with a published row and the T4S is not.

What one order is

Camso sells a set, in one line, and says so in one sentence:

4 track systems (2 front, 2 rear) & adapted mount kit to fit tracks on your vehicleCamso, X4S — What’s included, read 2026-09-26

Four units and the mount kit for your machine. The four units are the same product on every vehicle; the mount kit is the part keyed to the year, model and trim. That division is worth holding onto, because it is what makes the cross-platform rating real rather than rhetorical: if the X4S is going on a quad in winter and a side-by-side the winter after, the units carry over and the vehicle-specific hardware is what you buy again.

The published warranty is a 2-year limited warrantycovering manufacturing defects in materials and workmanship. One condition on it does not appear on the product page: Camso’s warranty page states the warranty is valid when an authorized dealer installs the system, and not valid otherwise. If you were planning to fit it yourself in the yard, read doing it yourself and the warranty first and settle it in writing before the deposit.

The X4S next to the T4S, row by row

This is the comparison the X4S exists to lose or win, so here is the whole of it. Camso publishes the same specification table on both product pages, which makes the two directly comparable — a rare thing in this category.

18 of those 22rows are the same figure on both pages. Belt width, belt length, lug height, footprint, the envelope of one unit, what the install adds to the machine, the sprocket range, the frame material, the anti-rotation assembly, the warranty — identical. Anyone telling you the X4S is a bigger or stronger system than the T4S is not reading the same pages.

4 rows differ, and two of them are just the rating restated. The two that are substantive are the unit weights and one line about the wheel bearings.

The weights, and which end you have to lift

Camso publishes 72.6 lb for an X4S front unit and 79.4 lb for a rear. The T4S publishes 71 lb and 83.7 lb. So the X4S front is marginally heavier and the X4S rear is the lighter of the two by a few pounds — and its front-to-rear spread is narrower.

On a spec sheet that is noise. In a shed it is not quite. The rear units are the awkward ones on either system: heavier than the fronts, and the pair you are lifting last when you are already tired of lifting. A narrower spread means four corners that feel more alike on and off the machine, and a storage rack whose shelves are interchangeable. If that is the axis you care about, off-season storage and trailering a tracked quad are where the weights actually bite.

There is no published figure for a fitted set. Camso publishes the units per corner and the mount kit at 6.25 lb (approx.), so if a trailer tongue or a shelf in the shed depends on the total, weigh it once and write it on the rack.

The one hardware sentence that is genuinely different

This is the row worth reading twice. Camso describes the wheels and bearings differently on the two pages, and the difference is not marketing shading — it is a maintenance difference. The X4S row reads:

5.3 & 7.9 in double bearing wheels. Standard and replaceable sealed bearings. Elastomer outer band. Bladder-type wheel cap.Camso, X4S — Wheels & bearings, read 2026-09-26

The T4S row, in the same position on its own page, reads encapsulated and sealed wheels including elastomer outer band. Molded bearing inside wheels. The wheel diameters are the same to within rounding. The bearings are described as replaceable on one page and molded into the wheel on the other.

That matters in year six, not year one. Mid-roller and idler bearings are the wear item on a track system that gets used in wet snow and spring mud — they are under water, under grit, and under a load that reverses every time the belt comes over the roller. A bearing you can press out is a bearing job. A bearing molded into a wheel is a wheel. Which parts are which on these units, and what each is called when you order it, is on what the parts are called.

The X4S page also lists double bearing hubs & oil bath housing among its features. Take the durability claim for what it is — a manufacturer’s claim — but the design choice behind it is the sort of thing that separates a set you keep for a decade from a set you replace wheels on.

What it does to the machine

The numbers that change how the quad behaves are the same as the T4S’s, and they are the ones to internalise before the first ride rather than after it.

Speed. Camso publishes an average speed loss of about 30%, up to 50% on some vehicles, and phrases the same idea elsewhere as keeping 2/3 of the vehicle's original speed. A tracked quad is not a fast machine and no set of tracks makes one. It also means the speedometer is reading a rolling circumference the machine no longer has, which matters the moment a posted limit applies — see roads and shoulders.

Width. The published offset width is 6 in. That is the figure that decides whether the machine still goes through the gate, down the trail between two trees, and into the back of the trailer it lived in last summer. Measure the gap before you order, not after.

Length and height. Offsets of F 24 in · R 27 in, and a published ground clearance of F: 15 3/8 in · R: 14 5/8 in. The machine gets longer at both ends and sits higher, which changes the approach angle onto a ramp and raises the centre of gravity on a side slope. Camso’s own manual puts a number on the second problem: do not drive across a slope with a bank angle of more than 15 degrees.

Which quads have an X4S published for them

There are 336 published X4S applications covering 331 distinct quads across 13 makes, model years 1986–2026. That is the broadest Camso ATV coverage there is, and it reaches back decades — a thirty-year-old quad is not automatically out of scope.

The interesting part is the small difference against the T4S list, because it is not random. 17 machines carry an X4S application and no T4S one. They come from Arctic Cat, Polaris and Textron, they run from 400 to 850cc, and every one of them is on independent rear suspension. All 17 also carry the same published condition, and it names what they have in common: Vehicle with cargo box.

Kimpex publishes no per-application condition data at all: every Commander WS4 record in this catalogue has an empty remarks field. The absence of a WS4 entry below means nobody has published a condition for it — not that none exists. Camso is the only manufacturer here that publishes these flags, so this page is necessarily a Camso view of the catalogue.

Read the machine names: TBX, X2, MV7. Those are the two-up and utility-bed quads — a dump or cargo box over the rear axle instead of a rack, sold as its own model. They are the heaviest, longest, most load-carrying quads any of these makes built, and they are the machines that sit closest to being a small side-by-side without being one. On that class, Camso publishes an X4S row and no T4S row.

Whether that reflects something about the system or simply where Camso chose to put its part numbers, the practical effect for an owner is the same: if your quad is on the list above, the X4S is the Camso system with a published fit, and the cross-platform rating stops being theoretical. What the flag on those rows actually costs you at install time — what comes off, what stays off — is in when the box is the problem. For the Arctic Cat and Textron machines in that table, the application detail is on the Arctic Cat applications and the Textron badge years.

It runs the other way exactly once: Arctic Cat 650 Mud Pro EFI 4x4 H1 (2010-2011) carriesa T4S application and no X4S one. Which is the general lesson of this whole section — on these two systems, the row for your machine decides, not the brochure.

The side-by-side half of the rating

If the second machine in the shed is a side-by-side, this is where the X4S earns its existence — but only in a band. Camso publishes three side-by-side ratings across its range, and they stack:

So on a mid-size machine — a 570 or 700 Ranger, a Pioneer, a Viking — Camso gives you two candidates, and they are not close in size. The 4S1 publishes a 14 in rear belt, a 116.7 in rear belt length, ground coverage of approx. 2520 sq. in. and unit weights of 103 lb front and 120 lb rear (powersports.camso.co, read 2026-09-26). The X4S is the light-duty answer: about a fifth less footprint, and units light enough that one person handles them off the machine.

That is the honest trade. On a loaded side-by-side breaking trail in deep snow, the 4S1 is the system built for the job. On a mid-size machine that mostly does chores and shares a shed with a quad, the X4S is the one set of tracks that serves both, and that is worth more than the flotation you gave up.

One caution on the transfer, because Camso’s own pages advertise switching vehicles and keeping tracks — on the T4S page as well as this one. The mount kit is what is keyed to the vehicle, so a genuine two-machine plan is one set of units and two lots of vehicle-specific hardware. Price both at the same time. The version of this that disappoints people is the one where the units are bought in November for the quad and the second mount kit turns out to be a spring order.

Which one to order

Order the X4S if there are two machines.A quad and a 400 to 700cc side-by-side, and you want one set of tracks between them: this is the only system in Camso’s range published for both, and nothing about the units gives anything away to the T4S to get that rating. It is the clean case.

Order the X4S if your quad is on the list above.A TBX, an X2, an MV7 — a quad with a box on the back. Camso publishes a row for those on the X4S and not on the T4S, and a published row beats an argument about how similar the two systems are.

Order it if the wheel bearings decide it for you. Replaceable sealed bearings against a bearing molded into the wheel is a real, published difference, and it is the one that shows up years later. It is a thin reason on its own. It is a good tiebreaker.

Otherwise the dual rating is capability you will not use.If there is one quad in the shed and no side-by-side coming, the side-by-side half of the X4S rating does nothing for you, ever. It is not a stronger system, a bigger system or a longer-lasting one — the table above is the proof of that, row by row. Get both quoted, and if the X4S costs more than the T4S on your machine, the extra is buying a rating you have nothing to use it on.

And do not choose either of them on displacement. The rating band tells you whether a system is plausible for your class of machine. The published application for your year, model and trim tells you whether it fits, what hardware comes with it, and what has to come off the quad to get it on. Those are different questions and only the second one is worth money.
