Features to know about

Adventure-Ready Truck Topper with Serious Load Capacity

westin exp truck topper

The EXP truck topper isn't just a shell. It's a launch point for whatever rig you're building. The modular aluminum design is strong without adding unnecessary weight, giving you the foundation you need for rooftop tents, recovery gear, or weekend hauls. With integrated top channels running front to back, it works seamlessly with crossbars and platform racks so you pick the setup that fits your style. And the 300 lb dynamic and 700 lb static load ratings let you carry heavy rooftop gear whether you're cruising the highway or posted up at camp.

Compatible With Westin Crossbars and Rack Systems You Already Use

Are you planning to run crossbars or a full platform rack? The integrated top channels are built to work with Westin's crossbars (W42PT and W62PT - sold separately), as well as trusted systems from Yakima, Thule, and Front Runner. If you have Yakima TrackTowers or SkyLine towers, Thule Rapid Podium feet, or Front Runner Canopy Load Bars, you'll be able to install them right into the channels. It's designed to give you options, not limits.

Side and Rear Access That Makes Packing and Camp Life Easier

No one wants to climb into the bed of their truck just to grab a duffel or cooler. The EXP's double-wall gullwing side and rear doors open wide and give you quick access to your gear. You don't have to crawl in or twist around just to get what you need. Each one uses locking T-handles to ensure everything in the back of your truck bed stays secure wherever you stop. It's perfect for grabbing bags at a trailhead or camp chairs when it's time to relax.

Reliable Protection From Dust and Rain

When the weather turns or the trail gets rough, this topper is built to keep your gear dry. It uses an EPDM sponge seal, which is a flexible, weatherproof material that stays tight over time and resists compression. The seal goes along every panel and door to help block out windblown dust and rain, so you don't open the back to find your bags soaked or coated in grime. It's the protection you want when you're hours from home and can't afford to lose what you packed.

Bolt-On Installation You Can Tackle at Home

This topper installs without drilling into your truck bed. It comes with all the necessary hardware and a step-by-step guide to walk you through the process.
