Best Skid Plates for 2010-2024 Toyota 4Runner: Winter Armor

The best skid plates for the 2010–2024 Toyota 4Runner (5th Gen) are deep-stamped 1/4-inch (6mm) aluminum plates that bolt on without drilling and never rust in road salt – and winter is exactly when they earn their keep. A snow-covered forest road hides the same frozen ruts, ice-locked rocks, and curb-height berms that a summer trail shows you in plain sight. Add six months of brine and salt spray from plowed highways, and an unprotected oil pan, transfer case, or control arm becomes the most expensive gamble on your truck. At NLP Performance in Tampa, FL, 4Runner owners from the salt belt order underbody armor every fall for one reason: a $350 plate is cheaper than a cracked aluminum oil pan on a frozen two-track.

Does a 4Runner Really Need Skid Plates for Winter?

Yes – winter is the hardest season on a 4Runner's underbody, and the factory plastic covers were never meant to take a hit. The 5th-gen 4Runner ships with a thin stamped-steel or composite engine cover that stops a stray pebble, not a frozen rock edge or an ice-packed rut. In the snow you lose your best defense: visibility. You cannot see the granite ledge under eight inches of powder, and the first thing it meets is your oil pan or transfer case.

Three winter-specific threats make dedicated skid plates a smart buy. First, hidden obstacles – packed snow and ice turn a known trail into a blind one, and high-centering on a frozen berm drags the whole belly across it. Second, road salt and brine – the same chemicals that keep highways clear eat bare steel and corrode exposed castings all winter. Third, reduced clearance in ruts – frozen wheel tracks funnel the truck lower than you expect, putting the drivetrain in the line of fire. A 4x4 5th-gen 4Runner has 9.6 inches of ground clearance, a 33° approach angle, and a 26° departure angle, but none of that helps once a tire drops into an ice rut and the frame settles onto a rock.

Aluminum vs. Steel Skid Plates: Which Wins in Salt Country?

For winter driving, 1/4-inch (6mm) aluminum is the better skid-plate material than steel because aluminum is effectively rust-proof even when its coating is gouged. Steel plates are strong, but the moment a rock chips the powder coat, bare steel starts corroding – and a winter of brine accelerates it. RIVAL's aluminum alloy relies on the metal's own corrosion resistance, so a scratched plate keeps protecting instead of rusting from the inside out.

Strength is not the trade-off you might expect, either. RIVAL's deep-stamped 1/4-inch (6mm) aluminum is thicker than the 3/16-inch stock that many steel plates use, and the stamped reinforcing ribs add rigidity without adding mass. The result is roughly 30% lighter than a comparable steel plate – a RIVAL connection plate weighs about 18.7 lbs (8.5 kg) – which keeps weight off the nose of the truck and protects your approach angle. Steel still has a place: it is cheaper per plate and shrugs off repeated hard rock strikes on dedicated crawlers, which is why ICON and DV8 use powder-coated steel for the lower-control-arm and rear-shock guards below. The smart winter build mixes both – aluminum for the big belly panels that see salt all season, steel for the small, cheap, high-abuse corners.

The Four Zones You Need to Armor

Full underbody protection on a 5th-gen 4Runner breaks into four zones, front to back: the engine and front belly, the transmission-to-engine connection gap, the front lower control arms, and the rear shock mounts. You do not have to buy all four at once – prioritize the engine skid, then work rearward as budget allows. Here is what each zone needs and the exact plate that fits the 2010–2024 truck.

1. Engine and Front Belly – RIVAL Aluminum Engine Skid Plate (Top Pick)

This is the plate to buy first. It covers the oil pan and front crossmember – the lowest, most exposed castings – in deep-stamped 1/4-inch (6mm) aluminum, and it bolts to factory points with no drilling or cutting. It fits the 2010–2024 Toyota 4Runner and the 2010–2023 Lexus GX460.

2. Transmission Connection Gap – RIVAL Aluminum TRD Connection Skid Plate

The connection plate closes the exposed gap between a RIVAL transmission skid and the TRD engine skid, so there is no unprotected slot for a rock or ice chunk to punch through. It is the same deep-stamped 1/4-inch (6mm) aluminum in a matte metallic silver finish and fits the 2010–2024 4Runner. At around $191 it is the budget-friendly way to finish a RIVAL belly system.

3. Front Lower Control Arms – ICON LCA Skid Plate Kit

The front lower control arms sit low and wide, right where ice ruts and plowed snow berms scrape. ICON's bolt-on steel LCA skid plate kit guards them and doubles as the lower-shock-mount locator for ICON's S2 Modular Performance Shock System, so a budget winter add-on also sets you up for a future shock upgrade. Per the store's fitment data it covers the 2010–2024 4Runner across SR5, Trail, TRD Off-Road, TRD Pro, Limited and more, plus the 2010–2014 FJ Cruiser.

4. Rear Shock Mounts – DV8 Offroad Rear Shock Skid Plates (Budget Pick)

At $99.99 the DV8 Offroad rear shock skid plates are the budget pick of this guide and a smart first buy if you are watching the bottom line – they fit the 2010–2023 4Runner and protect the exposed rear shock mounts that catch rocks and ice on the way out of a rut. They are high-grade steel with a micro-texture black powder coat, sold as a bolt-on pair, and they include integrated drain holes so slush, salt water, and grit flush out instead of pooling against the mount all winter.

2010-2024 4Runner Skid Plate Comparison

Here is how the four plates stack up by the zone they protect, how they are built, and what they fit. Prices run from about $100 for the DV8 budget pick to roughly $354 for the RIVAL engine skid – a complete head-to-toe winter build lands in the mid-hundreds.

How to Choose and Install for Winter

Choose by priority and budget: the engine skid is the non-negotiable first buy because it guards the oil pan and front belly, the parts a frozen rock destroys most expensively. If your budget is tight, the DV8 rear-shock guards at $99.99 or the RIVAL connection plate at around $191 get real protection on the truck now, and you can add the engine and control-arm plates before the deep-winter trips.

Installation on all four is bolt-on with no drilling or cutting, using factory mounting points – most owners finish a single plate in under an hour with hand tools and a jack. Two winter-smart tips: use a tap to clean the threads on all included hardware before final assembly so nothing seizes in the cold, and keep a funnel handy for oil changes, since RIVAL recommends one with any of their skid plates to avoid spills around the access area.
