Jeep Wrangler Cargo Carrier & Bike Rack Fitment for JK & JL Models

Modular Spare Tire Cargo Solutions for Jeep Wrangler

Looking for a Jeep Wrangler spare tire cargo carrier and bike rack that works for daily driving, trail runs, beach trips, camping weekends, tailgates, and real-world adventure?

rucRak’s GRUNT modular cargo system is engineered specifically for Jeep Wrangler owners who need:

• True rear tailgate access
• Spare tire compatibility
• Modular configurations
• Rust-free aluminum durability
• Rear availability preserved

This guide outlines fitment requirements for Jeep Wrangler JK (2007–2018) and JL (2018–Present) models and helps you select the correct GRUNT configuration.

Jeep Wrangler Model Compatibility

rucRak GRUNT fits Jeep Wrangler models equipped with a factory rear-mounted spare tire.

Compatible platforms include:

Jeep Wrangler JK (2007–2018)

2-Door & Unlimited 4-Door
Sport, Sahara, Rubicon, Willys, Freedom Editions

Jeep Wrangler JL (2018–Present)

Sport, Sahara, Rubicon, Willys, 4xe, High Altitude, Unlimited

If your Wrangler uses a factory rear spare tire mount, GRUNT is designed to integrate cleanly with no drilling or permanent modifications required.

Spare Tire Mount Requirements

Required configuration:

• Factory rear spare tire carrier
• Lug-mounted installation
• Proper torque during installation

GRUNT mounts directly to the spare tire assembly and is engineered to maintain structural integrity while supporting cargo or bikes.

Always confirm tire size and mounting configuration before ordering.

Tire Size Compatibility

GRUNT is compatible with most factory tire sizes including:

• 32”
• 33”
• 35”

If you are running:

• Oversized aftermarket tires
• Beadlock wheels
• Reinforced tire carriers
• Aftermarket bumpers

Contact rucRak prior to ordering to confirm compatibility.

Tailgate & Rear Access

Jeep Wranglers use a side-swing rear gate with integrated spare tire, making rear access essential.

Traditional hitch-mounted racks often:

• Block tailgate swing
• Reduce departure angle
• Require unloading to access the cargo area

rucRak GRUNT Advantage

• Maintains full rear swing gate access
• Spare-mounted design keeps hitch receiver free
• No unloading required for tailgate access
• Ideal for camping gear, coolers, tools, bikes, beach gear, and tailgates

Built for real Jeep travel — not parking lot show setups.

Hitch Receiver Considerations

Because GRUNT mounts to the spare tire:

• Your 2" hitch receiver remains available
• Tow within Jeep’s rated specifications
• Always follow Jeep’s published towing and tongue weight guidelines

Load & Weight Considerations

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

Account for:

• Dynamic load during driving
• Even weight distribution
• Secure fastening of cargo

GRUNT systems are designed for:

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

Fully loaded extreme rock crawling or articulation is not recommended.
