Stop letting the rocks win — heavy-duty sill protection with a solid step, 3 & 5mm steel, SA-made.
The Advanced 4x4 Jeep Wrangler JLU Rock Sliders are heavy-duty side protection sliders precision-engineered exclusively for the Jeep Wrangler JLU 4-Door (2018–Present) — fabricated from a combination of 3mm and 5mm mild steel for maximum strength where it counts. Designed to protect your sills, floor pan, and underbody from rock strikes, high-centring, and side impacts on technical trails, while also providing a solid step for cab entry and exit. Proudly manufactured in South Africa by Advanced 4x4 using advanced 3D scanning technology, every mounting point is matched to the factory JLU chassis geometry — no cutting, no welding, no fabrication required.
