Hennessey Sends Off the Hemi V8 With Limited Edition MAMMOTH 400
A special edition based on the 2024 RAM 1500 sport truck and produced in collaboration with Fox Factory.
Hennessey, renowned for its high-performance vehicles, has partnered with FOX FACTORY to create a limited edition of the 2024 RAM 1500 sport truck, the MAMMOTH 400. This special edition marks the final production run of the HEMI V8 engine, featuring a 5.7L V8 Ram 1500 Laramie, modified for enhanced performance and aesthetics.
The MAMMOTH 400 will be available in three color options: Viper Red, Viper White and GTS Blue, each decorated with heritage Viper Stripes. This design choice is a tribute to Hennessey’s history with the Dodge SRT Viper community. The truck boasts a lowered sport suspension system by FOX and Ridetech, designed to improve handling and provide a distinctive appearance. Exterior modifications include custom MAMMOTH 400 sport bumpers and side skirts, adding to its aggressive look. Customers can further personalize their vehicles with 22-inch wheels available in satin black or gloss black milled dark tint.
Powering the MAMMOTH 400 is a 420hp engine, ensuring it delivers the performance Hennessey is known for. “We are excited to partner with FOX to build a special sport truck with a uniquely American livery for the final Hemi V8-powered Ram trucks,” commented John Hennessey, the Founder and CEO of Hennessey Performance.
Limited to just 250 units worldwide, each MAMMOTH 400 comes with Hennessey badging and a serial-numbered engine plaque, underscoring its exclusivity — available for order now through authorized Chrysler, Dodge, Jeep, or RAM dealers.
