Roof Rack Riser Bar Kits

Unlock vertical freedom with our Roof Rack Riser Bar Kits

A great solution for adding solar panels and deck platforms above fans, AC units, or stacking gear like kayaks above these components, with no interference. Whether you're mounting a rooftop tent, kayak, storage box, or building a multi-layered solar deck system, these bars give you the strength, clearance, and configurability your build demands. Designed for dynamic builds:

• Choose from Standard crossbar length (rack width) or Extended length (~5" overhang each side). Both can be cut for a custom fit.
• Includes Flip‑style End Caps with Integrated Tie‑downs
• Made from 3/16″ Aluminum
• Flexible Mounting Options: 
  • • Brackets can mount on top of existing roof rack crossbars or to L‑Track slots in our deck panels.
    • Riser crossbars can be installed on top of the riser brackets or trimmed to fit below them, giving you about 1 3/16" of vertical adjustment to fine-tune your setup's roof clearance based on your needs. 
• Choose from Standard Support or Heavy Duty Kits:
  • • Standard: Maximum dynamic load is 150 lbs per kit. Ideal for solar panels, deck platforms, or general roof gear.
    • Heavy-Duty: Includes 2 extra brackets per crossbar for rooftop tents, or when extra support is needed. Maximum dynamic load is 250 lbs (while driving), 500 lbs while parked (static).

Roof Clearance:

Riser Bars provide approximately 2.7" to 6.2" of additional height above an existing Orion rack system*. All kits offer around 8.75" of total clearance from the center of the van’s roof to the bottom of a crossbar (when top-mounted) and 7.5" of clearance to the bottom of a crossbar (when bottom-mounted), giving enough space to clear centered roof appliances like fans or air conditioners. When mounted on deck panels, it adds +0.129" (deck panel thickness) to either configuration.

Mercedes Sprinter 

• Total bracket height: 3.9"
• Top-mounted: adds ~3.9" of clearance above racks crossbars (~4.9" to the top of the crossbar)
• Under-mounted: adds  ~2.7" of clearance above racks crossbars

Ram Promaster 

• Total bracket height: 7.7"
• Top-mounted: adds ~6.2" of clearance above racks crossbars (~7.2" to the top of the crossbar)

While our brackets and bars are built to handle serious weight, always follow your vehicle and rack manufacturer’s published limits to avoid structural risk. This system lets you keep permanent gear like solar panels mounted low, while adding usable crossbars for load‑outs above, a true multi‑layer rack solution for adventure vans and work rigs alike.
