Rugged Ridge Spartacus HD Spare Tire Carrier Wheel Mount Jeep Wrangler JL | 11546.57

Overview

The Rugged Ridge Spartacus HD Tire Carrier Wheel Mount (Part #11546.57) is the ultimate heavy-duty spare tire mounting solution for 2018–2025 Jeep Wrangler JL owners who run oversized tires up to 40 inches in diameter. Engineered specifically for off-road enthusiasts who demand factory-quality appearance without sacrificing extreme-duty strength, this wheel mount replaces the inadequate factory tailgate spare tire system with a rattle-free, fully adjustable platform that handles the amplified forces of serious trail driving. Whether you're building out a rock-crawling rig or a daily-driven overland Wrangler, the Spartacus HD Wheel Mount delivers the load capacity, adjustability, and durability your build demands.

Key Features & Benefits

• Fully-Welded Heavy-Duty Steel Construction — Distributes the weight of oversized spare tires evenly across a broad footprint, eliminating the flex and fatigue that destroys factory mounts.
• Supports Up to 40-Inch Wheel & Tire Combinations — Dramatically upgrades load capacity beyond stock limits, accommodating the largest aftermarket tire setups without compromise.
• Triple Adjustability System — Features depth adjustment for wider tires, tilting adjustment for bumper clearance, and a 3rd brake light bracket adjustment for safety compliance — giving you a truly custom fit.
• Angled Spare Tire Positioning — Adjustable mounting brackets allow the spare to be angled outward, easing one-handed access to the rear lift gate while gaining additional clearance over OE and aftermarket bumpers.
• Includes Camera & 3rd Brake Light Relocation Brackets — Comes with all brackets needed to reposition your backup camera and third brake light to comply with most state laws (light not included), so your factory safety systems remain functional.
• Durable Satin Black Powder Coat Finish — Tough, corrosion-resistant coating weathers the elements and maintains a clean, stealthy appearance that complements any JL build.
• MIL-SPEC Vibration Tested — Rigorously tested to a hybrid SAE/MIL-Spec standard simulating the sustained, vigorous vibrations of extended off-road driving — not just smooth-road use.
• OE & Aftermarket Bumper Compatible — Works seamlessly with factory rear bumpers and the vast majority of aftermarket bumper systems, eliminating fitment guesswork.
• No Drilling Required — Simple bolt-on installation to factory original mounting positions keeps your Wrangler's body intact and preserves resale value.
• Reuses Factory Stud Plate & Studs — Leverages existing hardware for a cleaner, more integrated installation with fewer new components to manage.
• Backed by Rugged Ridge's 5-Year Limited Warranty — Manufactured by Omix-ADA and covered under Rugged Ridge's industry-leading 5-year warranty against defects in materials and workmanship.

Fitment & Compatibility

The Rugged Ridge Spartacus HD Wheel Mount (11546.57) is engineered to fit 2018–2025 Jeep Wrangler JL (2-door and 4-door / JLU) models. Compatible with all trim levels including Sport, Sahara, and Rubicon running OE or aftermarket rear bumpers. NOT compatible with 4XE models equipped with the Pedestrian Warning Speaker, or Rubicon 392 models equipped with the Camera Shield. If you own a 2018 Wrangler, verify you have a JL (not a JK) before ordering.

Is this CARB compliant? Yes, this product is CARB (California Air Resources Board) compliant.

Do I need the hinge system separately? Yes — the Spartacus HD Tire Carrier Hinge Casting (Rugged Ridge Part #11546.56) is sold separately and required for a complete tire carrier installation. This wheel mount is designed to pair with that hinge system for maximum strength and stability.

Installation

The Rugged Ridge Spartacus HD Wheel Mount is a straightforward bolt-on upgrade that installs directly to factory mounting positions with no drilling required, reusing your Wrangler's factory stud plate and studs. Installation can typically be completed in under 2 hours with basic hand tools including a 13mm and 19mm socket. Red threadlocker is recommended on all bolt threads for long-term security. Take care to align the tailgate door properly during final installation — have a second person assist when lifting the spare tire into position. Torque specs: hinge to body 19 ft/lb (26 Nm); hinge to tailgate 15 ft/lb (20 Nm). Note: The Spartacus HD Hinge Casting (Part #11546.56) must be installed first and is sold separately.
