ARB R/T/Rail Suits Jl 4 Door

Combining functionality, strength, protection and a visually unique design, ARB has developed an ARB style of Rock Slider, not previously available for the Jeep platform. ARB Rock Sliders to suit the Jeep Wrangler JL 4-door are made up of both the slider assembly and a lower body mount to spread the load and protect the vulnerable lower-rocker area of the JL when used off road. (Note, due to slight differences in flare design between the Sport model and the Rubicon, there is reduced clearance between the JL Sport flare and the rock slider.) ARB Rock Sliders; 60.3mm Steel Tubing; Attaches to Vehicle Chassis; Multiple Mounting Points;

Protect the vulnerable lower rocker area of your Jeep Wrangler JL with ARB Rock Sliders engineered specifically for four-door models. Combining functional design, durable construction, and a distinctive appearance, these rock sliders help shield the vehicle’s lower body and rocker panels from contact with rocks, obstacles, and other off-road hazards. The vehicle-specific design supports a precise fit for compatible Jeep Wrangler JL applications from 2018 through 2020.
The ARB Rock Sliders feature a two-piece construction consisting of the slider assembly and a lower body mount. This design helps distribute impact loads across multiple mounting points while providing a strong connection to the vehicle chassis and sill. The slider section mounts to chassis-mounted body supports, helping reinforce the lower side of the vehicle without relying on cosmetic body panels alone. Durable steel construction is designed to provide dependable protection during trail use and technical off-road driving.
Finished in ARB’s Integrit textured-black powder coat, these rock sliders offer a rugged appearance and a durable finish suited to demanding environments. The laser-cut slider section is designed for strength and reliable coverage along the lower rocker area. Installation is vehicle-specific for the Jeep Wrangler JL four-door platform. Due to slight differences in flare design, clearance between the slider and the flare may be reduced on Jeep Wrangler JL Sport models compared with Rubicon models. Verify vehicle trim and application requirements before installation. ARB part number 4450240 is intended for Jeep Wrangler JL four-door owners seeking added rocker protection and a chassis-mounted off-road solution.
