Question:

Good afternoon, I have a Westin retractable tonneau cover with T-Slots on the sides and I am looking for a set of crossbars that work with this setup. Do you have a compatible set?

We sure do Will and welcome back! To add a set of crossbars to a Westin Retractable Hard Tonneau Cover like item # W57SH or item # W37JK, you'll need the Roof Rack for Westin Retractable Tonneau Covers item # W79ZK.

The Westin Roof Rack item # W79ZK comes with two 73" long crossbars with built in tracks for accessories. They'll attach to the T-slots on the Westin covers using the included mounting hardware.

The Westin Roof Rack item # W79ZK has a 300 lbs capacity. The crossbars measure 2" wide x 1-1/4" tall and are made of anodized aluminum and then powdered coated for protection.

What kind of gear do you plan on using the crossbars for? Feel free to answer this and throw in any other questions you have, where it says Add Comment.
