Leitner Designs ACS Roof Rack Add-On – For ACS Forged & Classic Bed Racks

If you’re running a Leitner Designs bed rack and need more space for a rooftop tent, recovery gear, or storage up top, this is the system we recommend. The ACS Roof Rack Add-On bolts directly to your existing ACS Forged or Classic rack, turning it into a full-length platform without sacrificing the modularity and side-access you already have.

The aluminum and stainless construction keeps weight low and strength high, with adjustable crossbars that slide in slotted tracks so you can dial in your layout. It’s clean, quiet, and made to carry serious loads—whether you’re traveling cross-country or just need the extra room for smarter storage.

Why We Recommend It

This is the best system we’ve found for anyone running a Leitner bed rack who needs a second tier of usable space. It gives you a strong, flexible mounting surface above the bed rack without compromising access to the gear below.
