On an open Polaris RZR 170 the machine pulls its own dust forward into the seats, and the UTV Zilla polycarbonate rear window shuts that path off with a 3/16-inch UV-stabilized panel that straps in without tools.
UTV Zilla builds it from name-brand Makrolon or Lexan polycarbonate, 3D CAD designed and CNC machined so the panel follows the cage line instead of leaving gaps at the corners. It is offered in clear or tinted, and neither version is hard coated.
Mounting is tool-less: heavy-duty straps with metal loops rather than plastic buckles, rated by the manufacturer to hold the window secure during riding and while trailering. Removable access panels let harness straps pass through, so you are not cutting the panel to fit a restraint.

Built To Solve: Trail Dust And Rear Weather Intrusion On A Polaris RZR 170
- An open rear end lets the machine draw its own dust cloud forward into the seats, which is why riders get coated even sitting up front
- Rain and spray come in from behind with nothing to stop them, soaking the seat backs
- Riding in a group means eating the dust of every machine ahead, then your own on top of it
- Cheap acrylic panels yellow, haze over and crack after a season in direct sun
- Panels mounted with plastic buckles work loose on rough trails and on the trailer ride home
- Cutting a solid rear panel to clear harness straps ruins the panel and leaves a dust gap
Best For: Dusty Desert And Group Trail Riding In A Youth Polaris RZR 170
- Parents riding dry, dusty desert and trail where airborne dust is the main complaint
- Group riders whose 170 is running behind other machines most of the day
- RZR 170s set up with an aftermarket harness - the removable access panels are built for exactly that
- Owners who already have a roof and windshield and want to finish closing the cab
- Choose tinted if sun and glare from behind are the problem or you want the cargo area hidden; choose clear and save money if keeping a clean rear view matters more
- Not the right pick if your 170 runs an aftermarket roof, cab enclosure or rear window add-on, which this panel may not clear

Fitment
Fits the Polaris RZR 170, all model years. UTV Zilla publishes fitment as RZR 170 (all years) and states no year range, so no year restriction is applied here.
Designed for the stock RZR 170 configuration. It may not fit alongside aftermarket roofs, cab enclosures, rear window add-ons, roof-mounted audio systems or mirrors with oversized clamps. Fitment is not guaranteed on applications that are not listed - check your machine's configuration before ordering.
FAQ
Does a rear window actually stop dust getting into the cockpit?
It stops the biggest source of it. On an open RZR 170 the low pressure behind the machine pulls your own dust forward into the seats, which is why riders end up coated even in front. Closing the rear opening with a solid polycarbonate panel removes that path. Dust can still come over the hood and in the sides, so a windshield is the other half of the job.
What is the difference between the clear and tinted versions?
Visibility and glare, not strength. Both are the same 3/16-inch UV-stabilized polycarbonate and neither is hard coated. Clear keeps the rear view as open as possible and costs less; tinted cuts sun and glare coming in from behind and hides the cargo area. If a parent is following the machine and wants to see the kid clearly, go clear.
Which RZR 170 model years does this fit?
UTV Zilla publishes fitment as RZR 170, all years, with no year range stated, so no year restriction applies. It is designed around the stock RZR 170 and may not fit with an aftermarket roof, cab enclosure or rear window add-on.
How thick is the panel and what plastic is it?
It is 3/16" thick polycarbonate, and UTV Zilla states they only use name-brand Makrolon or Lexan. The material is UV stabilized so it will not yellow and go brittle in the sun the way cheap acrylic does. Neither variant is hard coated, so it will scratch more easily than coated glass - wash it with water and a soft cloth, never a dry rag.
How does it mount, and is it secure enough for trailering?
It installs with tool-less heavy-duty straps that use metal loops rather than plastic buckles, and UTV Zilla rates the mounting to hold the window secure both during use and while trailering. Some initial assembly is required out of the box. It also has removable access panels so harness straps can pass through without cutting the panel.
Should I get this or the hard plastic roof first?
If you only buy one, the roof does more - sun and rain from overhead affect every ride, while dust is worst in dry, dusty conditions and when riding in a group. The rear window is the right next step after a roof and windshield, and the three together turn an open 170 into a mostly sealed cab.
Why UTV Zilla
UTV Zilla covers windshields, roofs and rear windows across Polaris, Can-Am, Kawasaki and Arctic Cat platforms, and the line is built to put real protection on a machine without premium-tier pricing. Panels are 3D CAD designed and CNC cut in the USA.
Two details separate this from a generic panel. UTV Zilla specifies name-brand Makrolon or Lexan rather than unnamed sheet, which is the difference between a window that stays clear and one that hazes in a season. And the straps use metal loops instead of plastic buckles, which is what keeps a rear panel in place on the trailer ride home.
Close Off The Rest Of Your Polaris RZR 170 Cockpit
A rear window stops the dust coming from behind, which is the worst of it, but the front is still open. Pair it with the UTV Zilla RZR 170 full glass windshield or the clear polycarbonate windshield, and add the hard plastic roof if the 170 is still running a bare cage. Decide between clear and tinted before ordering - they are the same material and thickness, so the choice is purely rear visibility versus glare and privacy. If you are replacing worn mounting hardware rather than the panel, the UTV Zilla quick straps and thumb screws are sold separately.
