This 2018 Jeep Wrangler Unlimited Sport 4×4 has been extensively upgraded with a professionally installed 6.4L HEMI V8 conversion, delivering approximately 505 horsepower in a proven JK platform. Offered by a private seller in Nashville, Tennessee for $48,000, this four-door Wrangler shows approximately 65,000 miles on the chassis, with just 10,000 miles on the HEMI drivetrain. Finished in factory Chief Blue over a black cloth interior, this example combines clean CARFAX history with a well-executed, performance-focused build.
- 6.4L HEMI V8 Conversion: Originally equipped with Jeep’s 3.6L Pentastar V6, this Wrangler has been converted using a 6.4L HEMI V8 swap kit from America’s Most Wanted 4x4 and installed by RubiTrux. The result is a substantial increase in power and torque, transforming the driving experience both on-road and off.
- Built Drivetrain to Match the Power: To support the added output, the axles have been regeared with G2 4.56 gears front and rear, improving drivability and torque delivery. ARB differential covers add durability, while the factory Command-Trac 4×4 system retains low-range capability for off-road use.
- Upgraded Braking & Chassis Reinforcement: A Teraflex big brake kit has been installed at all four corners to provide improved stopping power. The addition of a Rock Hard 4x4 front and rear roll cage system increases chassis rigidity and occupant protection.
- Suspension & Off-Road Capability: A MetalCloak 2.5-inch lift paired with JKS lower control arms enhances articulation and ride quality. The JK platform’s solid axle design, combined with these upgrades, makes this build well-suited for trail use or overland travel.
- Exterior & Lighting Enhancements: The truck rides on 17-inch Venomrex wheels wrapped in Falken Wildpeak A/T tires. Rough Country fender flares provide additional clearance, while ARB auxiliary lighting and Baja Designs windshield-mounted lights improve visibility in low-light conditions.
- Interior & Factory Features: Inside, the Wrangler retains its functional black cloth interior with seating for five, a 60/40 split-folding rear bench, and durable materials designed for open-air use. Factory equipment includes power windows and locks, remote keyless entry, air conditioning, cruise control, and a Uconnect infotainment system. Multiple storage compartments and a full-length center console add everyday usability.
About the Jeep Wrangler JK
Introduced for the 2007 model year and updated in 2012, the Wrangler JK marked a major evolution of Jeep’s iconic 4×4 platform. The Unlimited four-door variant expanded practicality while retaining solid axles, removable doors and roof, and strong aftermarket support. By 2018, the JK had become one of the most modified off-road platforms in the U.S., with extensive parts availability and a reputation for durability. Its combination of rugged construction and customization potential makes it an ideal candidate for builds like this HEMI-swapped example.
