Polaris RZR 4 Doors
A January whiteout doesn't care that you've got three kids and a cooler loaded in the back of your RZR 4. Cold air pours straight through an open cab at highway speed, and factory doors on the older 800 and XP 900 do almost nothing to stop it. That's the gap aftermarket doors close. TMW Offroad builds a steel-tube frame with an aluminum skin specifically for the XP 1000 and XP Turbo cage, and UTV Inc TIG-welds the same combination for the 900, 1000 and Turbo generation, so the whole crew stays out of the wind on a November hunting run instead of huddling under a blanket in the back seat.
Fitment splits along three cage generations. The 800 and XP 900 share one door profile, the 900, 1000 and XP Turbo share a second, and the newer Pro XP4, Pro R4, Turbo R4 and Turbo S4 platforms run a wider cage that most of the kits below weren't built for, so double-check your exact model before you order. Trail Armor and SuperATV both build for this category, and Moto Armor's 1/8 inch aluminum shell doors bolt to a broad span of the RZR 4 lineup. We're based in Wisconsin and winter our own machines here, so cold-weather gear on this page gets tested the same way you'll use it. Text us at (920) 644-5280 or call (920) 543-5376 and we'll match a door kit to your exact model before you spend a dollar.

What Separates a Real RZR 4 Door From a Knockoff
Gauge and welds are where cheap doors fail first. A steel-tube frame that's TIG-welded, like UTV Inc's, holds its shape after years of washboard trail. A tack-welded import frame flexes, and that flex is what makes a latch stop catching square after a season. Aluminum shells thinner than 1/8 inch dent on the first rock strike, which is why Moto Armor specs its panels at that thickness and calls it out on the product page. Precision-cut panels matter as much as the frame. A door cut loose around the opening rattles at speed and lets dust in, while a door cut tight to the cage closes with one motion and stays quiet. If you're running RZR 4 doors through a Wisconsin winter, pair them with a cab enclosure and a cab heater so the door isn't fighting a losing battle against an open front end. Whatever you choose, ask if the listing includes mounting tabs for a door bag. Skip it and you'll regret it the first time you're digging through loose gear on the floor.
Polaris RZR 4 Door Pricing: What You'll Actually Pay
The entry point for a full RZR 4 door set is $1,385 for UTV Inc's steel-tube frame, which gets you a TIG-welded frame and bolted aluminum panels at the lowest price in this lineup. Most buyers land around $1,647 to $1,649 for Moto Armor's aluminum shell doors, the sweet spot in this lineup: thick aluminum, a lift-off design, and a finish that comes in black powder coat or raw. The premium option is TMW Offroad's Sidewinder doors at $1,749.99 to $2,149.00, built specifically for the XP 1000 and XP Turbo cage with a center-hinge design that kills the rattle cheaper doors are known for. If you need to close a gap next to doors you already own, SuperATV's side panels run $69.95 to $74.95. The most common warranty is between 3 and 6 months, but Everything Polaris RZR does offer extended 1- and 2-year warranties on all products if that is something you are interested in. You can add the extended warranty right at checkout. SuperATV backs its own parts with a 3-month defect warranty on top of that. Every product on this page ships with a 90-day return window, and RZR 4 door kits run expensive enough that Affirm financing at checkout is worth a look if you're weighing the $1,647 aluminum kit against the $1,385 steel-tube set.

Polaris RZR 4 Door FAQ
Which RZR 4 generations do these doors fit?
Fitment splits by cage generation, not by trim name alone. The 800, XP 900, 900, 1000, S 1000, XP Turbo, XP Turbo S and Turbo S generally share one of two older cage profiles, while the newer Pro XP4, Pro R4, Turbo R4 and Turbo S4 platforms run a wider cage that most kits on this page weren't built for. Check your exact model and year before ordering, or text (920) 644-5280 and we'll confirm it for you.
Do I need to drill into my roll cage to install RZR 4 doors?
No. Every door on this page mounts to stock hardware or clamps to the existing tube. TMW's Sidewinder doors and Moto Armor's aluminum shells both use a lift-off or bolt-on design with no cage modification.
Are aftermarket RZR 4 doors as secure as OEM?
They close and latch the same way OEM doors do, but they aren't rated as anti-theft security devices or crash-tested safety equipment, and no listing on this page claims otherwise. What they do reliably is block wind, dust and debris, which is what most RZR 4 owners are actually buying doors to solve.
How long do aftermarket RZR 4 doors actually hold up?
A TIG-welded steel frame or a 1/8 inch aluminum shell should outlast the machine under normal trail use. The failure point is almost always the weather stripping or a tack-welded hinge on a cheaper import door, not the panel itself.
What's the difference between a full door kit and a side panel?
A full door kit like UTV Inc's or Moto Armor's replaces the stock door entirely. A side panel like SuperATV's is a filler piece that closes the gap next to doors you already own. It's not a standalone door and won't protect you without one.
