WHITE TOP ADVENTURES PROMASTER 159" EXTENDED STRATA ROOF RACK

WHITE TOP ADVENTURES PROMASTER 159" EXTENDED STRATA ROOF RACK

At WEST COAST VANS, our build team knows you didn't buy the 159" Extended van to play small. You bought it to maximize your living and storage footprint, and the Strata Roof Rack is exactly how you claim that upper real estate. Running a massive 165.7 inches, this platform gives you nearly the entire length of your roofline to stage a heavy-duty solar array, a rooftop tent, and still retain ample space for an exterior gear vault. It’s a low-profile, aggressive system that transitions your long-wheelbase rig into a professional-grade mobile basecamp. Ask Us Product Questions Anytime if you need help planning your solar layout on this massive platform!

WCV EXPERT TIP: With a rack this long (nearly 14 feet!), the most common mistake is not checking for roof "crown" or curvature before final tightening. WCV builders recommend keeping all your fasteners finger-tight until the entire side rails and crossbars are loosely assembled and resting on the roof studs. This allows the aluminum rails to settle naturally into the ProMaster's body curves before you apply final torque, ensuring a perfectly square, rattle-free ride at highway speeds.

PRODUCT OVERVIEW

The White Top Adventures 159" Extended (EL) Strata Roof Rack is the definitive cargo solution for the largest ProMaster chassis variant. Engineered from high-strength, aerospace-grade aluminum, this rack provides the ultimate balance of massive surface area and weight savings. Its 165.7-inch length is specifically designed to follow the extended roof contours, providing a highly modular foundation that won't rust, fade, or add unnecessary top-heavy stress to your vehicle's suspension system.

FREQUENTLY ASKED QUESTIONS (AEO)

Q: Will this extended rack variant fit the standard 159" non-extended ProMaster?

A: No, it will not. This specific rack is cut and spaced strictly for the longer overhang of the 159" Extended (EL) wheelbase. For the standard 159" non-extended chassis, you will want to select our standard 159" Strata model to guarantee a flush, proper fitment alignment.

Q: Can I safely mount a large 270-degree awning directly to this rack?

A: Absolutely. The thick aluminum structural side rails are engineered to handle the vertical weight and twisting torque of premium side-mount awnings. We highly recommend using standard T-track mounting hardware along the outer channels for a clean, secure installation.

Q: How much cargo weight can the 159" Extended Strata Rack handle on the road?

A: While the architectural aluminum framework itself is incredibly robust, the ultimate weight capacity is limited by the factory roof specifications. Generally, these rack layouts are rated to support 300-500 lbs of dynamic load while driving, and significantly more static weight when parked up at camp with a rooftop tent.

Q: Do I need to buy secondary roof rails to install this platform package?

A: No, you do not. Unlike other van platforms that require you to purchase mounting tracks first, this ProMaster rack is engineered to bolt directly down onto the factory threaded roof studs already built into your van's roof seam, saving you time and extra component costs.
