It's here, and it's marvelous!

Legendary off-road capability with impressive power and torque, the 392 is sure to bring a smile to your face.

They said it couldn’t be done — at least from the factory. While many aftermarket companies have shoehorned the HEMI V-8 (as well as GM LS V8 engines) under the hood of manyJeep Wrangler/Wrangler models, rumors suggested the eight-cylinder engine was too long to work with the crumple zones to meet federal crash test standards.

Jeep has done what many thought was impossible: say hello to the 2021 Jeep Wrangler Unlimited Rubicon 392 powered by a 6.4-liter HEMI V-8 mated to a TorqueFlite 8-speed automatic transmission and Selec-Trac full-time active transfer case. In JL Wrangler duty, the 6.4-liter makes 470 hp and 470 lb-ft of torque. Jeep claims the Wrangler Unlimited Rubicon 392 can reach 60 mph in 4.5 seconds and clear the quarter-mile in 13.0 seconds.

Other factory features include heavy-duty wide track Dana 44 axles with a 3.73 final drive ratio and Tru-Lok electronic locking differentials, transmission torque converter lockup control, a 2” lift and standard 33” tires on 17” beadlock-capable wheels.

With a total 10.3 inches of ground clearance, an approach angle of 44.5 degrees, a breakover angle of 22.6 degrees, and a departure angle of 37.5 degrees, and can traverse up to 32.5” of standing water, Jeep claims the JL Rubicon 392 is the most capable Jeep ever.
