Best Winter Fender Flares for 2020-2022 Jeep Gladiator JT

The best winter fender flares for the 2020-2022 Jeep Gladiator JT do one job extremely well: they keep salt, slush, and road spray off your paint and off the traffic behind you while you push through a Tampa cold front or a mountain ski run. Factory Gladiator flares are narrow, and the moment you fit a wider winter A/T or M/T tire, that tire throws a rooster tail of brine straight down the side of the truck. A proper flare contains that spray, protects the fender edge from salt corrosion and stone chips, and keeps you legal in states that require tire coverage. In this guide we compare four flare kits we actually stock for the JT — from a bolt-on composite set to steel off-road armor and a carbon-fiber show piece.

Why Winter Fender Flares Matter on a Gladiator JT

Fender flares are a winter protection part, not just a styling piece. On the 2020-2022 Gladiator JT, the factory flares extend only an inch or two past the sheet metal, which is fine on the stock 32-inch tires but inadequate once you step up to a 33 or 35-inch winter tire. Wider tires sling more slush, and in salted states that brine is what rots fender lips and rockers from the inside out. A flare that fully covers the tread width keeps the spray under the truck where it belongs.

There is also a legal angle. Many northern and mountain states carry fender-coverage statutes that require the tire tread to be covered to the contact patch. Running an aggressive winter tire that pokes past a trimmed fender can earn you a fix-it ticket. The flares below restore — and in the armor cases, extend — that coverage. At our Tampa shop we tell Gladiator owners heading north for the season to sort flares out before the tires, not after.

2020-2022 Jeep Gladiator JT Winter Flares Compared

Here is the quick-scan view. All four kits fit the 2020-2022 Gladiator JT (the Fishbone front set fits the shared JL/JT front fenders), prices run from about $500 to $1,620, and every one ships from NLP Performance. The Bushwacker is our budget and overall pick; the steel kits are for heavy off-road winter duty.

Best Overall: Bushwacker Flat Style Flares (4-Piece)

The Bushwacker Flat Style 4-piece kit is the best winter fender flare set for most 2020-2022 Gladiator JT owners because it is the only complete front-and-rear kit in this comparison and it costs under $500. Bushwacker molds these from Dura-Flex 2000 TPO, a UV-stable composite that stays flexible in sub-zero cold instead of cracking the way cheap ABS does when a snow bank or a parking-lot curb catches it. The flat, trimmed-fender profile sits tight to the body for a modern look while still covering tires up to roughly 35 inches when paired with a modest lift.

Best Rear Armor: Body Armor 4x4 Rear Flares

The Body Armor 4x4 rear fender flares are the pick when you want steel over the bed-side fenders instead of composite. These are a stamped-steel rear pair finished in textured black that fit the 2020-2023 Gladiator JT, and they shrug off the ice chunks, salt grit, and trail debris that a plastic flare would eventually scar. Because they are rear-only, most owners pair them with a steel front set (see Fishbone below) for a matched, high-clearance winter look that also makes room for taller tires.

Toughest Front: Fishbone Offroad Steel Front Flares

The Fishbone Offroad steel front fender flares are the most durable front option for a winter-built Gladiator. They are a laser-cut, powder-coated steel pair that bolt to the front fenders the JT shares with the 2018-plus Wrangler JL, so a single set clears bigger winter tires and takes a direct hit from an ice chunk or a snow-hidden rock without flinching. Note the store fitment tags list the shared JL platform; the Gladiator uses the identical front clip, so confirm your trim at checkout and you are good. Many owners add aftermarket LED side markers through the provided openings for extra visibility on dark, snowy mornings.

Want the steel look with less weight on the nose? Fishbone also offers the same front flare in aluminum (around $710), which trims heft while keeping the armored profile — a smart middle ground for a lifted Gladiator that still sees pavement commutes through the salt.

Premium Pick: Anderson Composites Carbon Fiber Front Flares

The Anderson Composites carbon-fiber front flares are the premium, weight-saving choice for a 2020-2022 Gladiator JT that doubles as a show truck. Real pre-preg carbon fiber shaves weight off the nose versus steel while adding a high-gloss finish, and because carbon does not corrode, salt is a non-issue. At around $1,620 for the front pair this is a build-statement part rather than a value buy, which is why it sits outside our $150-$900 everyday recommendation — but if the rest of the Gladiator is carbon-trimmed, these finish the look.

How to Choose Winter Flares for Your Gladiator

Start with tire size and how hard you wheel. If you run a stock-to-mild winter tire and want one clean kit that covers the whole truck, the Bushwacker 4-piece composite set is the answer — full front and rear coverage, no drilling on most trims, and the lowest price here. If you run 35s or bigger and the Gladiator sees real snow trails, move to steel: a Fishbone front pair plus a Body Armor rear pair gives you a matched, high-clearance setup that survives impacts composite cannot. Carbon from Anderson is the choice only when weight and show finish outrank budget.

Also weigh coverage versus clearance. Flat-style and open steel flares sit tighter to the tire for an aggressive look and better clearance, but a deeper flare sheds more slush off the body. For pure salt-season paint protection a full composite set like the Bushwacker contains the most spray; for maximum tire clearance on a lifted winter rig the steel armor flares win. Whatever you choose, torque the hardware to spec after the first few cold cycles — fasteners settle as the panels contract in the cold.
