ONCA Landcruiser 70 Series Dual Cab Extreme Rock Sliders

Premium Heavy-Duty Rock Sliders for the LandCruiser 79 Series Dual Cab

Upgrade your dual-cab Cruiser with rock slider protection engineered to withstand Australia’s toughest terrain. The ONCA Extreme Rock Sliders bring superior strength to your vehicle’s side-impact and ground-scrape zones — built to last, built for adventure.

Mandrel-Bent Tube Construction – Maximum Strength

ONCA sliders are manufactured from D50×2 mm mandrel-bent tubing — a true heavy-duty construction method that preserves full internal diameter in each bend, maintaining wall thickness and structural integrity when impact forces strike. Unlike conventional compression-bent tubing that weakens at curved points, these rock sliders deliver consistent rigidity across the entire length.
Perfect for serious 4×4 off-roading and remote-area touring, this construction safeguards your vehicle’s rocker panels and side-undercarriage from rock hits, root tangles and steep obstacle engagements.

Full-Length, High-Mount Design – Ground Clearance Retained

These rock sliders extend the full length of your LandCruiser 79 Series dual cab, providing complete rocker-panel protection from front to rear. Combined with a high-mount profile, they maintain vital ground clearance so you can traverse ruts, drops and rocky terrain with confidence.
This means you don’t have to sacrifice clearance for protection — a must for overlanders and tradies alike who demand both durability and mobility.

Engineered Mounting – Three-Point Chassis Clamp System

The ONCA design features a robust three-point chassis clamp and bolt-on mounting system. By distributing impact loads across three secure points rather than just two, force is spread efficiently across the chassis, reducing stress concentration and improving long-term durability.
Installation remains DIY-friendly, with bolt-on fitment that maintains resale value (no welding) and ensures compatibility with air-bag systems and heavy-duty off-road usage.

Reinforced Gusset Mountings & Premium Finishes

Each slider incorporates reinforced gusset mountings built to handle extreme off-road conditions. With heavy-duty steel reinforcement and precision laser-cut top-step platforms, these units combine form and function. The standard finish is a black powder coat for corrosion resistance, with polished stainless steel backing plates for the lettering — and optional colour-coded plate upgrades for those who customise their rigs.
Whether you’re touring the red centre, crawling coastal sand tracks or working on site, the sliders retain structural integrity and visual quality.
