When FCA finally pulled the cover off of the Wrangler 392 last month, they answered a decades long cry from fans and buyers alike. In fact, so many folks have wanted a Jeep Wrangler with eight cylinders that entire businesses have been set up to build them aftermarket. RubiTrux Conversions in Boone, North Carolina has been building customized and engine-swapped Jeeps for 20 years, and their latest project blows the recent factory effort out of the water. That is because this particular 2-door JL Wrangler packs an 808 horsepower 6.2L supercharged Dodge Demon V8 engine.
RubiTrux hasn’t given out much information about this Jeep Wrangler, which is likely the result of it being a customer car. That said, a recent YouTube upload does give us a chance to see this modified SUV in all of its glory. The swap itself looks like it could have been done at the factory, which is a testament to the 300+ SRT engine swaps the team has completed. The engine is backed by the ZF 8HP75 8-speed automatic transmission, as well as a billet machined transfer case adapter. The company notes that they only OEM-supplied parts in their builds, including all the necessary Mopar adapter parts.
The build also appears to wear one of RubiTrux’s lift kits, as well as their signature choice of 37-inch tires. Look at this Jeep from the outside and the only real hint you have as to what is going on is the small Demon decal near the front fender. Inside is a different story however, where the SUV has received a sinister makeover. The seats have been replaced with sportier units, which now feature red accent stitching and an embroidered Demon logo.
Driving a 2-door Wrangler on 37-inch tires with 808 horsepower under foot sounds like a bit of a handful. Watching this thing ignite its rear tires is an exercise in hilarity however, which is only exacerbated by the whine of that 2.7L supercharger. Nobody truly needs an 800+ horsepower Demon V8 in their off-roader, but we’d sure like one.
This sort of engine swap isn’t cheap however. RubiTrux charges $58,850 to swap a standard Hellcat motor into a JL Jeep Wrangler or JT Gladiator. This price is sure to increase thanks to the premium the Dodge Demon V8 crate engine carries over the “lowly” Hellcat. That said, we’re pretty sure you can’t but this experience for less anywhere else.
