Polaris Sportsman Track Systems
All three ATV track systems we sell publish applications for the Sportsman — and so, on one machine, does a fourth that is not an ATV system at all. The question on this page is not whether tracks fit; it is which system, and which kit your particular Sportsman takes. That second question is the one that catches people out: Polaris has built the Sportsman with two different front A-arm shapes, and the kit follows the A-arm rather than the engine.

Which Sportsman trims have published track applications
Read down to your trim, then across to see which systems we can actually supply a kit for. 232 applications across 12 trims, taken from our own catalog rather than from engine size — a machine is on this table because a kit is published for it, not because it looks like one that is.
Two things to check before ordering. Camso publishes two different Sportsman kits split by front A-arm shape — straight or arched — and displacement will not tell you which you have. And Camso’s application guide carries a remark against 19 Sportsman rows, three of them remark G, “permanent interference”. This is not a machine where every application is a clean bolt-on.

The 4 systems with published Sportsman fitment
Coverage first, price second. The counts below are this machine's own published applications, not the system's catalog-wide total, so a system that fits one trim of yours cannot look like one that fits all of them.

What the manufacturers publish
Quoted from Camso and Kimpex, not converted or re-measured. The two companies do not measure ground coverage the same way and neither says how, so read those figures against each other with care.

Sources, read 30 August 2026: Kimpex WS4 · Camso X4S · Camso T4S · Camso 4S1.
- Kimpex WS4: Kimpex publishes 1.5 hours for a first installation and 30 minutes for each subsequent swap, and runs three wheels on the ground with no slider shoe. Like the WSS4 it ships in two bolt-pattern variants — 4/110, 4/115 and 4/137, or 4/156.
- Camso X4S: Camso rates the X4S to 700cc on a side-by-side. On a larger machine the 4S1 is the system Camso publishes, not the X4S.
- Camso T4S: The T4S and the X4S publish identical track length, width, lug height, ground coverage, frame and sprocket range — verified against both Camso pages. What separates them is the rating: the X4S is also published for side-by-sides from 400 to 700cc, and the T4S is not. Unit weights differ slightly too (T4S 71 lb front / 83.7 lb rear; X4S 72.6 / 79.4).
- Camso 4S1: The 40 km/h figure is real speed; the manual notes it reads about 70 km/h on the vehicle speedometer.
What actually differs
What changes between one Sportsman kit and the next
The track units are the same product on every machine they fit. What is specific to yours is the hardware that attaches them and the gearing that drives them — which is why fitment is published per trim and per year rather than per engine size.
The one claim this page used to make that was wrong
The previous version of this page said that no permanent modifications are needed and that track systems bolt on using existing suspension mounting points. Camso’s own August 2026 application guide does not support that. Nineteen Sportsman rows carry a remark: ten are H, “vehicle with cargo box”, six are C, “temporary body parts removal”, and three are G, “permanent interference”. Most Sportsman applications are indeed a bolt-on. Three of them, by Camso’s own marking, are not — and which is which depends on the exact model and year, so it is worth asking us before you buy rather than after.
Straight or arched A-arms, and asymmetric sprockets
Camso splits its Sportsman applications by front A-arm shape, exactly as it does on the Can-Am Defender — 24 records say “straight a-arms” and 18 say “arched”. The sprocket counts are worth reading too, because they do not follow displacement in a straight line and they are not always the same front and rear: the Sportsman 450 takes 17 teeth at the front and 16 at the rear, the 325 takes 16 and 15, and the 900 takes 17 and 18. The sprocket is a property of the machine, not of its engine size.
The one Sportsman that takes a side-by-side system
There is a single Camso 4S1 application in the entire ATV catalog, and it belongs to the Sportsman: the 6x6 / Big Boss / Magnum, 2009 to 2014. The 4S1 is Camso’s side-by-side system, rated for machines from 400 to 1000cc, and the six-wheeler is the only quad it publishes for. If you are running a 6x6 that is your row on the table above, and it is a different system at a different price from everything else on this page.

What Polaris Sportsman owners run tracks for
Plowing and property work
The most common reason a Sportsman ends up on tracks. Kimpex publishes 2,045 square inches of flotation surface for the WS4 against roughly 2,000 for either Camso system — close enough that the choice rests on other things.
Hunting access on soft ground
Both manufacturers sell these as four-season systems. Kimpex lists marshland, mud, sand, dirt road and gravel for the WS4 alongside its snow ratings.
Getting through winter on a machine you already own
Once the vehicle-side hardware is fitted, Kimpex publishes 30 minutes to swap between tracks and wheels — the number that decides whether a set gets used all winter or twice a year.
Ownership
Before you order, and after it arrives
What ships, what the install involves, and what you will be buying again in a few seasons.
What arrives, and what else you need
A Camso kit is four track systems — two front, two rear — plus the mount kit adapted to your machine, on one line. A Kimpex Commander install is separate line items: the track kit, then the adapter for your machine, then the anti-rotation hardware. The Kimpex track kit on its own will not mount to a Sportsman.
Bolt pattern decides the kit variant
Kimpex sells the WS4 in two bolt-pattern versions — 4/110, 4/115 and 4/137, or 4/156 — at the same price. Which one you need is a property of your hubs, not a preference. Tell us the pattern along with the model year.
Installation and warranty
Kimpex publishes 1.5 hours for a first WS4 installation and 30 minutes for each subsequent swap. Camso’s two-year limited warranty is stated as valid when the system is installed by an authorized dealer. Kimpex publishes two different Commander warranty terms — three years on its Commander microsite, one year plus one on registration on its US warranty page — so confirm which applies before relying on either.
What you give up
Kimpex publishes 35% speed loss for the WS4. Camso publishes an average of about 30% across its systems and up to 50% on some vehicles, and describes the T4S as keeping two thirds of the vehicle’s original speed. Those are the manufacturers’ figures for the systems, not measurements we have taken on a Sportsman.
Wear parts and diagrams
Bearings, hubs, sprockets, tread and tensioners, searchable by the serial number on your unit.

Transfer kits adapt a set you already own to a different chassis. Which parts you need depends on both machines, so check the pairing before you sell the Sportsman.

Polaris Sportsman track questions we get asked
By model and year rather than by engine. Camso publishes both variants across the Sportsman line — 24 of its records specify straight front A-arms and 18 specify arched — and the table above shows which trim rows carry both. This is the same split Camso applies to the Can-Am Defender, and it is the most common ordering mistake on either machine. It is worth thirty seconds on the phone.
On the Sportsman, remarkably little. We checked both Camso product pages directly: the T4S and the X4S publish identical track length, track width, lug height, ground coverage, frame material and sprocket range. What differs is the rating and the weight. The X4S is also published for side-by-sides from 400 to 700cc, where the T4S is quad-only, and the units weigh slightly different amounts — T4S 71 lb front and 83.7 lb rear, X4S 72.6 and 79.4. If you only ever intend to run it on the Sportsman, the two put the same rubber on the ground.
Yes, and it is the one Sportsman that takes a different class of system. The 6x6 / Big Boss / Magnum from 2009 to 2014 is the only quad in the entire catalog with a published Camso 4S1 application — the 4S1 being Camso’s side-by-side system. It is a different kit at a different price from everything else on this page, so read your own row on the table rather than the row above it.
Far more than this page used to claim. It previously listed the 450, 570, 850 and XP 1000. The catalog publishes applications from the 325 up to the 1000 — twelve displacement classes across more than two decades of model years, 2002 to 2026. Read the table above for your own displacement and year; if your machine is not on it, that means no published application exists rather than that tracks are impossible, and it is worth a call.
Plowing is one of the two things people buy these for, and both manufacturers photograph their ATV systems with a blade fitted. What we will not do is tell you that tracks make a Sportsman unstoppable with a plow on the front — the manufacturers publish speed loss, not plowing performance, and the honest thing to say is that tracks trade speed for grip and flotation. Weight on the front end and your plow’s own mounting clearances are worth checking against the track units before you order.
