Quick Answer: For most overlanding trucks and SUVs, ARB’s Under Vehicle Protection kit (about $599-807 depending on vehicle fit) is the best skid plate overall — 3mm zinc-plated steel across four modular panels covering the oil pan, transmission, and transfer case, with confirmed fitment for the Bronco, 4Runner, and Tacoma. Need full-system coverage for a Jeep Wrangler JL? Rough Country’s Engine + Transfer Case + Gas Tank kit (about $799) protects everything underneath in one bolt-on system. On a tighter budget, DV8 Offroad’s front skid (about $220) covers the front undercarriage for a fraction of the price — just know it leaves the transmission and transfer case exposed.
A skid plate is the one piece of overlanding gear you hope never to need — until a rock, stump, or hidden ledge is inches from your oil pan on a trail with no tow truck in range. Coverage varies more than most buyers expect: a single front plate and a full underbody system solve different problems, and even some factory setups leave real gaps. Here’s how the material and coverage choices actually break down, and which kits are worth bolting on.
Skid plate facts worth knowing
- Many factory and single-plate kits leave the transmission exposed even when the oil pan is covered — documented specifically for the Ram 1500 (oil pan, transfer case, and fuel tank protected, but “no factory skid plate under [the transmission] on any Ram 1500,” per off-road parts retailer Juggernaut’s Ram 1500 skid plate guide) and the Ford Ranger (factory skid leaves the transmission, catalytic converters, and transfer case bare, per Juggernaut’s Ranger guide).
- A full steel skid system for a Jeep Wrangler JL weighs around 150-160 lb — Rough Country’s Engine + Transfer Case + Gas Tank system is listed at roughly 157 lb by retailer ExtremeTerrain — versus roughly 100 lb for an equivalent aluminum system, a real tradeoff to weigh against an already-loaded overlanding rig.
- Toyota’s factory TRD skid plate is actually 1/4-inch stamped aluminum with plastic trim, not the bare plastic or thin steel many buyers assume — a detail worth confirming on your own trim before deciding an aftermarket upgrade is unnecessary.

1. ARB Under Vehicle Protection — Best Overall
ARB Under Vehicle Protection Kit
- 3mm press-formed, laser-cut steel, zinc-plated then powder-coated for corrosion resistance.
- Four-panel modular kit covers steering, oil pan, transmission, and transfer case — more complete than most single-plate kits.
- Confirmed current fitment for the Ford Bronco (2021-2026), Toyota 4Runner (including KDSS-equipped trims), and Tacoma.
- Bolts to factory mounting points on supported vehicles — no drilling required.
ARB earns the overall pick because it’s the rare kit that covers all four vulnerable points — steering, oil pan, transmission, and transfer case — in one modular system, with confirmed fitment across three of the most common overlanding platforms. That’s meaningfully more coverage than a $220 front-only plate, for less than half the price of a full custom bellypan.

2. Rough Country Engine + Transfer Case + Gas Tank System — Best Full System for Jeep JL
Rough Country Skid Plate System
- Covers the engine, transfer case, and gas tank in one bolt-on system — no cutting or drilling.
- 3/16" steel construction built for Jeep Wrangler JL 4-door 3.6L trims (2018-2022).
- At roughly 157 lb for the full system, it's a real weight addition worth factoring against an already-loaded rig carrying a rooftop tent and gear.
- Closes the exact gap that trips up many factory setups: full-length fuel tank protection, not just the oil pan.
If your Jeep JL’s factory setup leaves the fuel tank or transfer case exposed, Rough Country’s system is the straightforward fix — one bolt-on kit instead of piecing together three separate plates from different brands.
3. Rock Hard 4x4 Complete Bellypan System — Best Heavy-Duty
Rock Hard 4x4 Complete Bellypan Skid System
- The most complete coverage in this roundup — a full front-to-rear steel bellypan, not a modular add-on kit.
- Built specifically for Jeep JL/Gladiator platforms, with individual aluminum transfer-case skids also sold separately for buyers who want to mix materials.
- Premium pricing reflects full-vehicle coverage and heavier-gauge steel than the front-only or three-piece kits above.
- Best suited to buyers who wheel technical, rock-heavy trails regularly rather than occasional overlanding trips.
The Rock Hard system is overkill for a weekend overlanding trip on graded dirt roads, but it’s the pick for anyone whose trail diet includes genuine rock crawling, where a three-piece bolt-on kit is more likely to have gaps at the seams than a purpose-built bellypan.
4. RCI Off-Road Engine Skid Plate — Best for Tacoma/4Runner
RCI Off-Road Engine Skid Plate
- 3/16" CNC laser-cut steel with black powdercoat, built specifically for 4th-gen Tacoma and 4Runner platforms.
- Covers the oil pan, front differential, and radiator crossmember in one plate.
- Sold modularly — separate transmission (about $383) and transfer-case (about $304) skids are available from the same brand if you want full coverage in stages.
- Vehicle-specific fit means no universal-kit compromises on clearance or mounting points.
RCI’s modular pricing is the practical pick for Tacoma and 4Runner owners who want to start with engine protection now and add the transmission and transfer-case plates later, rather than committing to a full system up front.
5. DV8 Offroad Front Skid Plate — Best Budget
DV8 Offroad Front Skid Plate
- 3.5mm steel with a micro-texture black powder coat, built for the 2024-2026 Toyota Tacoma.
- Bolts to 4 factory mounting points, protecting the intercooler and front undercarriage.
- The most affordable steel option in this roundup at roughly a quarter of ARB's or Rough Country's price.
- Front-only coverage — the transmission, transfer case, and fuel tank remain exposed, so pair it with a rear belly skid if you run technical trails often.
DV8’s plate is the right call for buyers who mostly drive graded dirt and gravel forest roads and just want cheap insurance against the occasional rock or rut, not full underbody armor for technical trails.
How to choose a skid plate
Start with where you actually drive: graded dirt roads and moderate trails are well-served by a single front plate like DV8’s, while technical rock trails call for full coverage like ARB’s four-panel kit or Rough Country’s three-piece system. Check what your factory setup already protects before buying — some trims cover more than buyers assume (Jeep Rubicon’s factory front skid is real steel), while others leave real gaps (Ram 1500 and Ford Ranger both lack factory transmission protection). Then weigh steel against aluminum: steel resists punctures better and costs less, aluminum saves weight, and the actual difference between product lines varies more than the material alone suggests.
The bottom line
For most overlanding trucks and SUVs, ARB’s Under Vehicle Protection kit is the skid plate worth bolting on — four-panel steel coverage across the most common overlanding platforms for less than a full custom bellypan. Running a Jeep JL and need complete coverage in one kit? Rough Country’s Engine + Transfer Case + Gas Tank system closes the gap for about $799. On a budget or mostly driving graded roads? DV8 Offroad’s front skid covers the basics for about $220. And whatever you choose, pair it with traction boards, a winch, and rock sliders — a skid plate protects the underbody, but the rocker panel on the side needs its own armor when the trail goes off-camber. Running dusty trails or water crossings on the same build? A snorkel kit protects the engine’s air intake the same way a skid plate protects what’s underneath it.
