SoFlo Customs Offers Factory-Calibrated 505-HP HEMI V8 Swaps for Jeep Wrangler and Gladiator

SoFlo Customs brings 505-HP HEMI V8 power to existing jeeps

SoFlo Customs has opened nationwide orders for 6.4-liter HEMI V8 conversions for the Jeep Wrangler JL and Gladiator JT, giving owners a way to upgrade their existing vehicles with the 392 powertrain without purchasing another Jeep. The Florida-based company offers a complete engine and transmission installation service, including vehicle transportation, factory-specification powertrain programming and return delivery.

The conversion centers on a new Mopar 6.4-liter HEMI V8 producing 505 horsepower and 470 lb-ft of torque, paired with a new eight-speed automatic transmission. SoFlo Customs collects vehicles from customers across the contiguous United States, completes the conversion at its Florida facility and typically returns them within three weeks. Round-trip transportation is included in the advertised package pricing.

The service addresses a longstanding gap in Jeep’s factory lineup. While the Wrangler Rubicon 392 brought V8 power to the JL generation, the Gladiator JT has never received a factory 392 variant. Owners seeking substantially more power have traditionally faced the expense of trading in a customized vehicle or undertaking an aftermarket engine swap.

“People spend years getting a Jeep exactly the way they want it, and then the only way to get the engine they want is to get a new one. We want to make that engine upgrade as absolutely seamless as possible.” said Joe Ghattas, founder and CEO of SoFlo Customs.

Factory 392 Calibration Is Central to the Conversion

A defining feature of SoFlo’s package is its use of Jeep’s factory 392 powertrain calibration rather than a bespoke aftermarket engine tune. The company flashes the powertrain control module (PCM) with the factory software and reconfigures the vehicle’s immobilizer, ignition and gateway modules to work with the replacement powertrain.

According to SoFlo Customs, this approach allows the speedometer, tachometer, coolant-temperature gauge and oil-pressure readings to function correctly. The company also says the system retains original-equipment closed-loop fuel management and remains accessible to Chrysler dealer diagnostic equipment and emissions-testing systems.

The conversion harness is approximately 90% plug-and-play, with no wiring splices required, according to the company. These integration details are particularly important for modern JL and JT platforms, where engine management, security systems and vehicle electronics must communicate properly for the completed swap to operate as intended.

New Mopar Components and Warranty Coverage

Rather than relying on a salvaged donor vehicle, SoFlo Customs builds each conversion around a new Mopar crate engine and a new eight-speed transmission. The package also includes a 3.5-inch stainless-steel exhaust system, cold-air intake, exhaust manifolds, engine oil cooler, high-flow fuel pump where required, air-conditioning compressor, coolant reservoir and associated hoses.

Additional components include a high-output alternator, replacement belts, 392-specific engine mounts, adapter plates and electronic control module relocation brackets. The parts package carries a 24-month or 24,000-mile warranty, while installations performed by SoFlo Customs receive 12 months of labor coverage.

The 3.6-liter Wrangler and Gladiator conversions retain the factory fuel pump, while the 2.0-liter turbo Wrangler requires an upgraded fuel pump and transmission, according to the published specifications. All listed prices include installation and round-trip shipping within the contiguous United States.

Owners need to provide their address, vehicle identification number and current mileage to initiate the process. Customers who prefer to use their own repair facility can also purchase the conversion kit separately and send their PCM to SoFlo Customs for factory-specification programming, with the company quoting a turnaround of up to ten days for the module.

By combining a new 392 powertrain with factory-based electronic integration, SoFlo Customs is positioning the conversion as an alternative to replacing an existing Jeep. The service’s appeal will depend on the value owners place on retaining their customized vehicles, as well as the costs, warranty terms and practical implications of a substantial aftermarket powertrain conversion.
