Ford Bronco Cargo Rack Fitment Guide


Modular Cargo & Bike Rack Solutions by rucRak

Looking for a Ford Bronco 2021+ spare tire cargo carrier and bike rack that works for daily driving, beach trips, camping weekends, overlanding, tailgates, and real-world travel?

rucRak is engineered for Bronco owners who need true rear access, modular configurations, and long-term durability — not a single-use rack.

This vehicle-specific guide explains fitment, tire compatibility, weight considerations, and the recommended rucRak configuration for the Ford Bronco 2021+.

Ford Bronco Model & Year Compatibility

rucRak GRUNT fits Ford Bronco 2021+ models equipped with a factory rear-mounted spare tire.

Compatible with most Bronco trims including:

  • Base
  • Big Bend
  • Black Diamond
  • Outer Banks
  • Badlands
  • Wildtrak
  • Everglades
  • Heritage Edition

Works with factory spare tire carriers.

No drilling or permanent vehicle modifications required.

If your Bronco has a factory rear spare tire mount, GRUNT is designed to integrate cleanly.

Spare Tire & Mount Requirements

Required configuration:

  • Factory rear spare tire mount
  • Secure lug-mounted installation
  • Proper torque installation required
  • GRUNT mounts directly to the spare tire assembly and engineered to maintain structural integrity while supporting cargo or bikes

Always confirm tire size compatibility before ordering.

Tire Size Compatibility

GRUNT is compatible with most factory tire sizes including:

  • 32” factory tires
  • 33” factory tires
  • 35” factory tires

If running oversized aftermarket tires, heavy beadlock wheels, or aftermarket bumpers, contact rucRak before ordering to confirm compatibility.

Tailgate & Rear Access

The Ford Bronco uses a side-swing rear gate with attached spare tire — making rear access critical.

Traditional hitch-mounted cargo carriers can:

  • Block tailgate swing
  • Interfere with departure angle
  • Require unloading to access the rear

rucRak GRUNT Advantage

  • Maintains full swing gate access
  • Spare-mounted design keeps hitch free
  • No unloading required for rear access
  • Ideal for coolers, camping gear, beach equipment, bikes, tools, luggage, and tailgate setups
  • Designed for real Bronco travel

Hitch Receiver Considerations

One major benefit of GRUNT:

It keeps your 2" hitch receiver available for towing.

Because GRUNT mounts to the spare tire:

  • Hitch remains open
  • Tow separately within Ford’s limits

Always follow Ford’s published towing and tongue weight specifications.

Load & Weight Considerations

Follow Ford’s published spare tire carrier and rear swing gate weight limits.

Consider dynamic load, not just static weight.

Distribute cargo evenly and secure all gear.

GRUNT systems are designed for:

  • Highway driving
  • Daily Bronco use
  • Gravel roads
  • Light off-road conditions

Heavy rock crawling or extreme articulation use is not recommended while fully loaded.

Limitations & Special Notes

  • Use one primary configuration at a time (cargo or bikes)
  • Carrying cargo and bikes simultaneously is not recommended unless explicitly supported.
  • Spare-mounted systems extend rear vehicle profile.
  • Check fasteners frequently during long trips.
  • Rear camera visibility is maintained but may be partially obstructed depending on cargo placement.
  • Always follow Ford’s published weight guidelines

6 Years of Field Tested Engineering

We spent 6 years torturing this cargo system on the trails so you don't have to. Built strictly from customer feedback, the Gen 10 Grunt & Gunny are the toughest, most versatile setups we've ever released.

What changed?

  • 35% Thicker Heavy-Duty Aluminum: We upgraded the basket, table, and mounting plates from .125 to high-tensile .190-thickness H32 aluminum. This means maximum structural rigidity and zero trail flex under heavy loads.
  • New Dual-Tier Cargo Capability: The tailgate table now pulls double duty. It can lock into place as an upper-deck cargo platform, instantly giving you two distinct tiers of organized gear storage.
  • 17% Larger Tailgate Table Workspace: We expanded the surface area to a massive 36" x 15.5" layout. It gives you a wider, flat platform optimized for camp kitchens, heavy tools, or trailside prep.
  • Integrated Support Legs (No More Lost Pins): We completely re-engineered the fold-down mechanism. The table now features rugged structural legs that rest securely on the frame, eliminating the old loose locking pins that easily get lost in the dirt.
  • Clear Rear-View Visibility: When stowed, the table can now be dropped down lower out of your sightline, keeping your rear window completely clear for safer daily driving and trail backing.
  • 3-Inch Height Ergonomics: The upper table mechanism is now height-adjustable by up to 3 inches, letting you lower the deck for easier reach, loading, and better clearance with oversized gear.
  • Upgraded Heavy-Duty Mounting Plates: We expanded the footprint of the mounting plate on the Gunny to provide rock-solid stability and eliminate trail vibration. For the Grunt, we engineered 4 additional positions of height adjustability, letting you dial in the exact clearance your specific rig needs.
  • Redesigned Backup Camera Shield: The new integrated camera surround/cover plate has been structurally reinforced to provide maximum impact protection against trail debris. This sleek redesign optimizes your rear sightline for an uncompromised backup camera view while adding extra clearance adjustability for the tailgate table.
  • Rattle-Free Trail Engineering: Re-engineered tolerance joints and secure leg mounts mean the Gen 10 stays completely silent over washboards and rock gardens. No annoying metal-on-metal clanging on the highway or the trail.
