2014-2025 RAM Promaster 159" High Roof Low Pro Roof Rack


Description

The Flatline Van Co. Low Pro Roof Rack for the RAM Promaster 159" High Roof is the go-to upgrade for van builders, overlanders, and full-time travelers who demand function without compromise. Engineered specifically for 2014 and newer Promaster 1500, 2500, and 3500 models with a 159" wheelbase and high roof, this rack is built to carry your gear, your solar, and your lifestyle. The all-aluminum construction keeps total rack weight to just 68 pounds, and the aerodynamic front fairing cuts through wind to help protect your fuel economy on long hauls.

Six adjustable, 80/20-compatible crossbars give you complete flexibility to position accessories exactly where they need to go - whether that's a MaxxAir fan, a rooftop AC unit, solar panels, or kayak carriers. The drop-in hardware slots make adding accessories quick and clean, and the rack integrates seamlessly with the Promaster Side Ladder and Fiamma F45S awning. Installation is a genuine DIY job that most builders complete in under 90 minutes with basic hand tools.


Key Features

  • Total Rack Weight - 68 lbs: All-aluminum construction keeps the rack remarkably light without sacrificing strength or rigidity.
  • 6x Adjustable Crossbars: Move crossbars forward or backward anywhere along the rails to accommodate fans, AC units, solar panels, and other rooftop accessories.
  • 10-Series 80/20 Compatible Crossbars: Anodized aluminum crossbars accept a huge range of aftermarket mounting hardware and accessories without drilling or modification.
  • Drop-In Hardware Slots: Built into each crossbar for fast, tool-free accessory attachment - solar panels, gearboxes, and kayak carriers mount up in a flash.
  • Lightweight Aluminum Front Wind Fairing: Aerodynamic fairing reduces wind drag compared to bulky competitor racks, helping maintain fuel efficiency on long trips.
  • All Stainless Steel Hardware: Every bolt and fastener is stainless steel for corrosion resistance and long-term durability in any climate.
  • Powder-Coated Black Finish: Clean, matte black finish resists rust and UV fade while looking sharp on any Promaster build.
  • Fiamma F45S Awning Compatible: Side rails are designed to mount the Fiamma F45S awning directly - the F45S 350 is recommended, and the F45S 300 also fits.
  • Side Ladder Compatible: Engineered to work seamlessly with the Flatline Van Co. Promaster Side Ladder for full rooftop access.
  • DIY Installation - Under 90 Minutes: Straightforward installation with included step-by-step guide; no professional install required for most builders.
  • Fitment: 2014+ RAM Promaster 1500/2500/3500 | 159" Wheelbase | High Roof only.

Fairing Options & Which to Choose

  • Normal Fairing: The standard aerodynamic front fairing. Reduces wind drag, improves fuel efficiency, and gives the rack its signature low-profile look. The best choice for most builds - ideal if you are not planning to run a light bar or off-road driving lights on the front of the rack.
  • Fairing with 50" Light Bar Cutout: Same aerodynamic fairing, but pre-modified with precision cutouts sized to fit most 50" LED light bars. Perfect for off-road builds, overlanders, or anyone adding a light bar to their setup. Flatline recommends the Baja Designs ONX6 50" Arc LED Light Bar for this fairing. Note: light bar is not included.

Manuals & Guides


FAQ

Will this rack fit my Promaster with a standard (low) roof?

No - this rack is designed specifically for the Promaster High Roof configuration with a 159" wheelbase. It will not fit standard or medium roof Promaster vans. Be sure to confirm your van's roof height and wheelbase before ordering.

Can I mount solar panels directly to this rack?

Yes. The 10-series 80/20 compatible crossbars with built-in drop-in hardware slots make solar panel mounting straightforward. Most standard solar mounting brackets designed for 80/20 rail systems will work directly with this rack.

Does this rack work with the Flatline Van Co. Side Ladder?

Yes - the Low Pro Roof Rack is specifically engineered to integrate with the Flatline Van Co. Promaster Side Ladder. The two products are designed as a system for seamless rooftop access.

Can I mount a Fiamma F45S awning to this rack?

Yes. The side rails are designed to accept the Fiamma F45S awning directly. Flatline recommends the F45S 350 for the best coverage, but the F45S 300 is also compatible.

Which fairing option should I choose?

If you do not plan to run a light bar or off-road driving lights, go with the Normal Fairing - it gives you the clean aerodynamic look without the cutout. If you want to add a 50" LED light bar now or in the future, choose the Fairing with 50" Light Bar Cutout. Flatline recommends the Baja Designs ONX6 50" Arc LED Light Bar for that fairing. Note that the light bar itself is not included with either option.

How long does installation take, and do I need professional help?

Most installations are completed in under 90 minutes using basic hand tools. This is a genuine DIY install - no professional installer is required. A detailed step-by-step installation guide is included, and Flatline also provides installation guide PDFs for both fairing variants.

Does the rack affect fuel economy?

The integrated aluminum front fairing is designed to reduce wind drag compared to bulky traditional roof racks, helping minimize the fuel efficiency impact of carrying a full roof rack system. Real-world results will vary depending on load, speed, and driving conditions.
