The Rock Slide Engineering rear quarter side rails are rack components designed for 2015–2022 Toyota Tacoma bed racks to add structural support and tie-in points at the rear quarter. They integrate with the Tacoma bed rack system to improve load distribution and securement options for cargo and accessories. These rails are a targeted upgrade for Tacoma owners adding overland or utility gear to their existing rack.
