Polaris RZR 4 Bed and Tailgate

A four-seat RZR means four sets of boots, coolers, and gear bags that all need somewhere to go once the cab fills up. Picture a Pro XP loaded for a weekend at deer camp: rifles locked in double gun boots, a slide-out cooler holding the drinks, and a 16-gauge steel rack carrying the rest above the bed floor instead of buried under it. That's the difference between a bed that works for four people and one that just holds junk.

We stock gear for the whole RZR 4 lineup, from the 800 and XP 900 up through the Pro XP, Pro S, and Turbo R/S, and fitment needs to be checked against what you’re specifically running. A bed cover built for a stock cage won't necessarily bolt to a custom aftermarket cage, and a rack anchor for a Polaris factory lock and ride system uses a different part number than a universal mount. Moose and Rough Country both build to real bed dimensions instead of guessing, which is why their gear shows up across our top sellers. If you're not sure what fits your specific RZR 4, text us at (920) 644-5280 or call (920) 543-5376 and we'll match the part to your machine before you spend a dollar. As the deepest Polaris RZR aftermarket catalog online, we'd rather spend five minutes confirming fitment than sell you the wrong bracket.

Buyer’s Guide: How to Choose Polaris RZR 4 Bed and Tailgate Accessories

Bed and tailgate gear for the RZR 4 falls into five categories: fixed cargo racks, adjustable multi-mount racks, weatherproof bed covers, slide-out cooler trays, and in-bed gun boot mounts. Each solves a different hauling problem, and most RZR 4 owners end up running two or three of them together.

Type	Material	Best For	What You Give Up
Fixed Cargo Bed Rack	16-gauge HRPO steel, powder-coated, 44" L x 28" W	Heavy loads on a flat deck under the cage	No weather protection; mounting brackets and lock-and-ride anchors sold separately
Adjustable Multi-Mount Rack	CNC laser-cut U.S. steel, 3-stage powder coat	Mixed gear like fuel cans, chainsaws, and tie-downs in one system	Higher cost, and color upgrades add to the price
Weatherproof Bed Cover/Trunk	Weatherproof shell, direct cage mount	Keeping gear dry and out of sight	Fits specific cage types only, so check yours before ordering
Slide-Out Cooler/Fridge Tray	Powder-coated steel, ball-bearing slides, 250-lb capacity	Fast access to a cooler or 12V fridge	Takes up a dedicated 31" x 19" footprint
In-Bed Gun Boot Mount	Powder-coated steel, universal bolt-in	Securing firearms on hunting trips	Boot cases sold separately; holds two guns max

Steel Gauge, Coatings, and Mounts: What RZR 4 Bed Gear Should Actually Have

The RZR 4's extra length and extra passengers put more flex on the frame every time the bed gets loaded. Look for 16-gauge steel or heavier on fixed racks, since anything thinner tends to oil-can under a full cooler and a rack of tools. Powder coating matters more than paint here. It resists the chip-and-rust cycle that trail dust and rock chips cause on bare or painted steel. One thing that trips up a lot of first-time buyers: a bed rack often ships without its mounting bracket or lock-and-ride anchors, since those are model-specific and sold separately. Check the "what to order" list on the product page before checkout, or you'll be waiting on a second shipment before the rack actually bolts down.

What a Polaris RZR 4 Bed and Tailgate Setup Actually Costs

The budget-friendly entry point sits around 98 to 210 dollars, which gets you a single-purpose piece like a powder-coated gun boot mount or a 250-pound-rated cooler slide tray. Most RZR 4 owners land in the sweet spot around 320 dollars for a full-width steel cargo rack that handles the bulk of trail hauling without needing anything fancier. At the top end, a CNC laser-cut adjustable rack or a cage-mounted bed cover trunk runs from about 890 up to 1,450 dollars, and that's the bees-knees version for owners who want a fully configured system with RotoPaX mounts, tie-down slots, and a locked, weatherproof compartment built in.

Most items ship within 24 hours, and any exceptions show a lead time right on the product page. 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, and you can add the extended warranty right at checkout.

Polaris RZR 4 Bed and Tailgate FAQs

Does a bed rack cut into rear passenger legroom on the RZR 4? No. Bed racks mount in the cargo bed behind the rear seats, not in the passenger area. Most bolt-on racks clear the stock RZR 4 cage, though if you've added an aftermarket cage extension, check the listing to confirm clearance first.

Will a bed cover fit if I've already got an aftermarket cage? It depends on which cage. The TMW Offroad bed cover trunk is built for TMW Offroad cages and stock cages only, so confirm your cage brand before ordering rather than assuming it's universal.

Do I need to buy anything extra to install a cargo bed rack? Often, yes. The Moose bed rack, for example, ships without its mounting bracket or lock-and-ride anchors since those are sold separately and vary by model. Check the "what to order" section on the product page so you're not waiting on a second shipment.

How much weight can RZR 4 bed accessories actually hold? It varies by product. The Rough Country cooler tray is rated to 250 pounds, while rack capacity depends on the steel gauge and mounting points used. Check the individual listing for a hard weight rating before loading up.

Can I run a cooler tray and a full-width bed rack at the same time? Usually, but it depends on your bed's available length once both footprints are accounted for. The cooler tray alone measures 31 inches by 19 inches extended, so measure your remaining bed space before ordering both.
