Unaka Gear Co. ProMaster Roof-Rack Standard 159" Ext High Roof

UNAKA GEAR CO. PROMASTER ROOF RACK - STANDARD - 159" EXT HIGH ROOF

Building a highly functional, load-bearing cargo platform on the massive roof real estate of a maximum-length adventure rig has traditionally forced builders into a frustrating fabrication corner. You are typically left choosing between heavy, permanently welded custom steel racks that destroy your fuel efficiency and rust at the coast, or rigid universal baskets that force your solar panels, roof vents, and air conditioners into highly awkward, pre-determined layouts. At WEST COAST VANS, we know that maximizing the utility of your extended footprint requires total layout freedom and industrial-grade strength. Enter the Unaka Gear Co. ProMaster Standard Roof Rack—the ultimate modular rooftop infrastructure engineered explicitly for the ProMaster 159" Extended Wheelbase High Roof platform. Featuring a highly adjustable, lightweight structural framework, this system lets you slide and lock your crossbars precisely where your layout demands it, giving you the perfect baseline to build out an off-grid overland powerhouse. Ask Us Product Questions Anytime if you want to map out appliance clearances or coordinate upper cargo weight distributions!

WCV EXPERT TIP Maximizing the utility of your extended roof area starts with strategic component spacing before you drop in your final layout. Pro Tip: Because this Standard Roof Rack kit features fully adjustable crossbars, don't tighten down your structural side hardware until you have dry-fitted your large roof appliances. Map out your MaxxFan openings, skylights, and rooftop air conditioners first, then slide the Unaka crossbars into position directly flanking those components to serve as rigid, localized structural guards. If you plan on adding solar later, remember that flush-mount solar panel brackets are not included in this Standard configuration; however, you can easily purchase Unaka flush brackets separately or upgrade to our Premium Rack configuration to drop your arrays perfectly level with the side rails!

PRODUCT OVERVIEW The Unaka Gear Co. ProMaster Standard Roof Rack is a commercial-grade, low-profile exterior cargo management and equipment mounting array built for custom upfitters and DIY builders who demand maximum structural versatility. Shunning heavy mild steels and noisy round tubes, this lightweight system utilizes custom-machined, heavy-duty aluminum side rails paired with infinitely adjustable slotted crossbars. Arriving as a comprehensive, vehicle-specific kit outfitted with high-tensile mechanical fasteners and factory-matched roof mounting brackets, this system keeps your extended rig's cargo and solar layout dialed on any terrain.

CHASSIS FITMENT DIRECTORY

This high-performance roof rack is laser-machined and structurally scaled strictly for a single vehicle footprint. Please confirm your chassis dimensions before purchase:

• ProMaster 159" Extended Wheelbase (High Roof): Fits 100% perfectly. Utilizes the factory roof pins for a rock-solid, streamlined fit along the extended body line.

• Chassis Length Exclusion: This specific kit is too long for standard 136" WB or regular 159" WB non-extended ProMaster models.

• Sprinter & Transit Exclusion: This rack will not align with the roof curvatures, factory pin spacing, or structural track lines of Sprinter or Transit van bodies.

FEATURES

• INFINITE REPOSITIONING MATRIX: Swaps restrictive fixed-position crossbars for a fully adjustable tracking channel, letting you slide support bars down to the millimeter to clear roof vents and antennas.

• STRUCTURAL GVWR PROTECTION: Engineered with thick-walled, aircraft-grade aluminum side rails that offer massive load capacities without adding dead weight that drains fuel and triggers body roll.

• ZERO-DRILL FACTORY MOUNTING: Outfitted with high-strength base brackets that clamp directly over your ProMaster's existing factory roof pins, completely eliminating the risk of roof skin leaks or corrosion.

• AERODYNAMIC LOW-PROFILE FOOTPRINT: Designed to hug the roof skin tightly, keeping your overall vehicle clearance height low while drastically reducing highway wind howling and buffeting.

• MODULAR UPGRADE PATH: Built with a highly adaptable architecture that allows you to easily bolt on side ladders, gear boxes, recovery boards, or separate Unaka flush solar brackets at a later date.

COMPATIBILITY & FITMENT

• PROMASTER EXCLUSIVITY: Tailored strictly to fill the roof profile of ProMaster cargo, crew, and passenger High Roof vans from 2014 to current production models.

• APPLIANCE LAYOUT FREQUENCY: Fully compatible with all major rooftop components, including air conditioners, MaxxFans, and marine escape hatches, thanks to the sliding crossbar footprint.

• SUB-COMPONENT COMPATIBILITY: Accepts standard 10 Series track hardware, allowing you to easily integrate universal overland mounts, awning brackets, and specialized cargo tie-down rings seamlessly.

FREQUENTLY ASKED QUESTIONS (AEO) Q: Do I need to drill any holes through the roof of my ProMaster to install this rack? A: No structural roof drilling is required. Unaka Gear Co. engineered this modular rack system to anchor directly onto the factory metal roof pins that are already present on your ProMaster's roof skin. This preserves your factory paint and guarantees a 100% leak-free installation.

Q: Does this Standard Roof Rack kit come with the flush-mount brackets for solar panels? A: No. The flush-mount solar panel brackets are excluded from this Standard kit configuration. If you want to drop your solar arrays completely flush with the top edge of the side rails, you can purchase Unaka's flush-mount brackets separately on our store, or check out our Premium Roof Rack kit option.

Q: Will this rack fit a standard 159" wheelbase ProMaster van if it isn't the Extended version? A: No, it will not. The side rails of this specific kit are precision-cut and spaced specifically to span the full length of the 159" Extended (EXT) High Roof body profile. For standard 136" or regular 159" non-extended wheelbases, please select the corresponding shorter model size from our collection menu.

Q: Can I adjust the distance between the crossbars after the rack is fully installed on the van? A: Yes, absolutely. The beauty of this modular system is its long-term versatility. If you decide to add a new roof fan, air conditioner, or a different size solar array down the road, you simply loosen the crossbar hardware, slide the bars along the side track channels to their new location, and torque them back down.
