Add a flat, front-to-back mounting surface to your bed rack. The XTR Parallel Bars Set adds a bar that runs the length of your rack on the inside, parallel to the bedrail (not at an angle). That gives you a level, lengthwise mounting surface — perfect for mounting drawer slides, adding low side bracing, building a custom bottom surface, and more. A versatile structural addition to your bed rack accessories for anyone building out a storage or drawer system. Made from the same solid T-slot Xtrusion as your rack, each bar becomes more mounting surface for whatever you’re building — slide-out drawers for an overland kitchen, low bracing for heavy gear, or a flat base for a custom cargo floor. What you can do with it Mount drawer slides — a parallel front-to-back surface to build a slide-out drawer system on. Add low side bracing — extra structure down low for heavier loads. Build a custom bottom surface — a base for a cargo floor or platform. Expand mounting — more T-slot surface running the length of your rack. Choose your bracket angle & length The bars mount via angle-specific brackets — match the bracket type to your rack: 20D — standard angle (most racks). 13D — Softopper racks (except Gladiator). 9D — Gladiator racks. Then select your rack length to match the rack you ordered (46"–84"). Not sure which angle your rack uses? Email us before ordering. Estimated lead time: 4–5 weeks (cut to your rack length). Build out your bed rack Parallel bars are the foundation for a slide-out storage build. Mount the XTR Slide Out Kit on them for full bed-organizer access, add XTR Modular MOLLE Plates for gear up top, and an XTR Rotopax Adapter Plate for fuel and water. Need a rack?
