Fitting your Toyota 4Runner

The 4Runner has no bed but takes a full off-road accessory set: lift kits, roof racks, bumpers and armor, lighting, and cargo protection. The 5th gen (2010–2024) is one of the most modified SUVs in the country. The 2025+ 6th gen is new and fitment is generation-specific.

What fits your Toyota 4Runner

  • Lift kits from 2 to 4 inches, the most common 4Runner modification
  • Roof racks and roof rack platforms for overland builds
  • Front and rear bumpers, sliders, and skid plates
  • Cargo and floor liners, plus lighting for trail and highway

What we check before ordering

  • 5th gen (2010–2024) and 6th gen (2025+) take different parts

  • The KDSS suspension on some trims limits which lifts fit

  • TRD Pro is factory-lifted with different clearance

Toyota 4Runner fitment questions

Do 2025+ 4Runner parts fit a 5th gen?

No. The 2025 truck is a new generation with different suspension, body, and rack mounting. We confirm your generation before ordering.

What is the most common 4Runner build?

A 2 to 3-inch lift with all-terrain tires, a roof rack, and sliders. It is the classic 4Runner overland setup and the one we build most.

Does KDSS affect which lift I can use?

Yes. Trucks with the KDSS suspension system have restrictions on lift kits, so we confirm whether your trim has KDSS before recommending one.

About undercoating & rust protection

Rust is the slow killer of trucks in the Rio Grande Valley, and Brownsville has it worst. Salt air off the Gulf attacks the frame, rocker panels, brake lines, and every exposed fastener long before the body shows it. Undercoating is the cheapest insurance you can buy against it — a few hundred dollars now instead of a frame that is unsafe in ten years.
