The ARB Summit side step return is a durable steel side rail and integrated step that improves vehicle access while protecting front quarter panels and lower sills for 2017 MU‑X and Trailblazer applications. It fits PN 4448350 and is intended to work with ARB or OE sidesteps. While it offers strong barrier protection against rock ledges, it is not a dedicated rock slider for extreme crawling.
