WK2 Rock Rails

by: Chief Products

NOW SHIPPING

Chief Products WK2 Rock Rails deliver critical off-road protection for your WK2. The fully integrated design compliments your Jeep's good looks while also providing maximum off-road clearance. To deliver improved rigidity and better impact force distribution than any of our competitors, we utilise high-strength steel and (27) body connections (per rock rail). The smooth ‘boat bottom’ design protects key underbody elements while ensuring you can easily slide over off-road obstacles. Our NO TREAD, TREK ELEVEN and SAFARI THREE editions provide a rigid step that has been optimised to keep obstacles away from the sides of your WK2, while also providing easy entry (or convenient access to your roof rack). Our industry-first system of clamping plates and flush mounted bolts delivers unparalleled ease of installation, while also ensuring everything looks great when you open the doors. Best of all, to ensure you’ve got the best looking WK2 on the trails, we provide (2) tread plate options that allow you to stylise your WK2 Rock Rails however you choose.

They’re perfect for anyone looking for a purpose built protection option for their WK2.

    MORE INFO
    EASY TO UPGRADE - You can easily upgrade WK2 Rock Rails (NO TREAD) at any time by adding - WK2 Rock Rails (Tread KIT).
  • Off-Road Protection
    Provides off-road protection for the rocker panels and lower doors of your WK2. Our design also provides protection for the body seam and wiring loom that run along the underside of your WK2.

    High-Strength
    Made from High-Strength Steel with a design that incorporates more body connections than our competitors to improve rigidity and provide significantly better impact force distribution. Through FEA computer modelling and (8) months of real world testing we've delivered high-strength rock rails that you can rely on when you need them most.

    Great Style
    Our design team paid attention to every line, so we could deliver rock rails that compliment the lines of your WK2 with a fully integrated appearance. Open the doors and you immediately notice the attention-to-detail with our streamlined design and flush mounting bolts. Best of all, we provide (2) tread plate options so you can stylise your WK2 Rock Rails however you choose. The dual layer design of the tread plates utilises a silver lower plate that looks great and provides an instant wow factor.

    Convenience
    The steps have been optimised to keep obstacles away from the sides of your WK2, while also providing easy entry (or convenient access to your roof rack). Through real-world testing we ensured you could easily step out over the steps without hitting your leg. We even tested our tread plates to ensure small feet (or paws) wouldn't have troubles with the openings in the tread plates.

    Maintains Off-Road Clearance
    Since our design replaces the OEM plastic rocker panels, (rather than bolting below) it maintains maximum off-road clearance.

    Jack Points
    We supply (1) reinforced jack point (front & rear) on the underside of each rock rail, for a total of (4) high-strength jack points. The small square openings allow drainage and are reinforced to support the entire weight of the vehicle.

    Smooth 'Boat Bottom' Design
    Our smooth 'Boat Bottom' design ensures that you can easily slide over off-road obstacles. There's nothing to get caught on off-road and all of the mounting bolts are tucked away and protected.

    Easy To Install
    Many rock rails for the WK2 are very difficult to install. Some can take up to (8) hours, while others require drilling and numerous nutsert installs. As a point of difference, our engineering team has delivered an install process that is extremely easy. We provide easy-to-follow step-by-step instructions. If you're half-way decent with a wrench you can install this yourself.

    Industry Leading Corrosion Protection
    We utilise E-Coat (Electrophoretic Coating) to provide the very highest corrosion protection available for steel automotive parts. Deposited from a water-based solution using a high voltage DC charge, the process coats all wet surfaces with an extremely tough and highly corrosion resistant finish that is unlike any other process. On top of that industry-leading electrophoretic coating we apply 80µm of extremely durable powder coat (advanced polyester thermosetting powder). Finally, whenever possible we build our products with highly corrosion resistant materials and fasteners (stainless steel, aluminium alloys, etc.) to provide enduring protection against corrosion when a coating is scratched or damaged off-road.

    Real World Testing
    There aren’t many off-road companies who own a WK2 as their daily driver, or regularly take it all over Australia in search of off-road adventures. In our opinion, that extra testing and passionate attention to performance leads to superior products.

    Top Quality Finishing Touches
    We include all the details that matter. High tensile zinc plated bolts for maximum strength and corrosion resistance. Wedge-Lock washers to create bolted joints that are extremely resistant to loosening. Anti-Seize for bolted joints that are resistant to seizing. A Chief Products Shop Rag for all the dirty jobs around the garage. All packaged with extreme care to arrive safely and looking great.
  • Bolts into existing mounting points in the frame, no drilling or cutting required. Replaces OEM plastic rocker panels.
