One rock too many and your 4Runner’s body is toast. These weld-on rock sliders are the armor your rig deserves strong enough to hold the entire weight of the vehicle, slide over obstacles like they’re nothing, and give you a bombproof Hi-Lift point anywhere along the rail. Choose DIY if you love the torch, or pre-welded if you want to spend less time fabricating and more time wheeling.
Key Features & Benefits
- Main frame: 2" × 2" × .120 wall square tubing – the backbone of serious protection
- Outer kick-out rail: 1.75" × .120 wall DOM round tubing for maximum strength and smooth sliding
- Full vehicle weight-bearing legs – park the whole 4Runner on these with zero flex
- Hi-Lift jack compatible along the entire length – get yourself out when the trail gets ugly
- Two kit options: Full DIY (pre-bent & pre-cut) or Pre-Welded main tube with loose legs
- Sold as a pair – driver + passenger side included
- Shipped raw – paint or powder-coat however you want
Feel the confidence of knowing your rocker panels are safe, your rig sits higher on the rocks, and you finally have a jack point that won’t fold when you actually need it.
DIY Kit vs Welded Kit – Which One Is Right for You?
- DIY Kit – All tubing pre-cut and pre-bent. You notch, cope, fit, and weld everything yourself. Perfect for fabricators who want total control and the satisfaction of building it from the ground up.
- Welded Kit – Main slider arrives fully notched, fitted, and welded. Legs ship loose so you still weld them on at the exact angle and position you want. Saves hours of work while keeping it custom.
How to Install Your Weld-On Rock Sliders
- Strip factory plastic side steps / running boards
- Locate and clean frame rail weld zones
- Clamp slider in position (level and equal gap both sides)
- Tack legs, check fitment, then fully weld with 7018 or quality wire
- Grind, prime, paint or powder-coat to match your build
Strong welds = lifetime protection. Take your time on fitment and these will outlast the truck.
Who These Rock Sliders Are For
These are for the 4th Gen 4Runner owner who actually wheels rock crawling Moab, hammering forest service roads, or building the ultimate overland rig. If “body damage” keeps you up at night, or you’ve already crunched a rocker and sworn “never again,” these sliders are your peace of mind in steel form.
Why Weld-On Sliders Are Essential
Bolt-on sliders can shift or tear off under real abuse. Weld-on means zero movement, maximum strength, and the lowest possible profile. When the trail tries to eat your 4Runner, these sliders eat the trail instead.
Frequently Asked Questions (FAQ)
Do these fit all 2003–2009 4Runners?
Yes — fits every 4th Gen 4Runner (including Limited, Sport, and SR5) with or without running boards.
Are they really strong enough to hold the full weight of the truck?
Absolutely. The 2×2 .120 wall frame and DOM outer rail with properly welded legs have been beaten on by countless rigs with zero failures.
Do I need a professional welder?
Good penetration and clean welds are required. If you’re comfortable welding frame material, you can do it. If not, any local fab shop can knock it out in an hour or two.
Can I add a filler plate or dimple-die kickout later?
Yes — the design leaves plenty of room for future upgrades like fill plates, grip tape, or extra tubing.
What’s the lead time?
2–3 weeks for fabrication and UPS Ground shipping. Everything ships raw steel.
Do you offer powder coating?
Not in-house, but they ship raw so you can have them coated locally in any color you want.
Are bolt-on versions available?
Currently only weld-on — because when it comes to real protection, welded is always stronger.
