NOT recommended for vehicles with aftermarket bumpers with integrated hitch

IF you have an aftermarket spare wheel (rim) or an aftermarket tire carrier please follow the guidelines below OR watch the video above to ensure proper fitment of your rucRak to your application.

NOTE 1: If you have an aftermarket wheel, measure wheel depth by placing a placing a yardstick or a level flat across the tire and measuring from the lug nut to the outside of the tire, see the image below noting 5-7/8".

If that measurement is MORE than 5-7/8", then you will need to add Mounting Stud Extensions to your order.

Fitment Note 1

NOTE 2 : If you have an aftermarket tire carrier, measure the tire height by placing a yardstick or a level inside the hitch and measuring from the center of the wheel to the top of the hitch, see image below noting <2-1/2".

If that measurement is MORE than 22.5", then you will need to add Feet Extension Set to your order.

Fitment Note 2

NOTE 3 : If you have an aftermarket tire carrier or a positive offset on your wheel, measure from the pin hole in your hitch to a virtual vertical line on the outside of your tire as shown in the mage below noting <14".

If that measurement is MORE than 14”, then you will need to add Pedestal Extension Set to your order.

Fitment Note 3

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 Jeep Wrangler Cargo Rack Advantage

Maintains full rear swing gate access
No unloading required for tailgate access
Ideal for camping gear, coolers, tools, bikes, beach gear, and tailgates

Our Jeep Wrangler Cargo Rack is built for real adventure— and parking lot show setups.

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.
