A Ram pickup with 777 hp is getting a bigger supercharger. For its SEMA display, Mopar is aiming past 900 hp, with a yellow cover under the hood to match the Rumble Bee name.
The truck is one of two custom Ram builds in Stellantis’ SEMA plans. Both are set for the November 3–6 show at the Las Vegas Convention Center in Nevada.
Its second truck starts with a smaller HEMI V8, then adds boost and a hood window that puts the hardware on view. Side-exit exhaust and a rear spoiler give it more than an engine upgrade.
The show trucks build on a new range of street-focused pickups. Ram’s stock 5.7-liter Rumble Bee makes 395 hp, with sales planned to start late in 2026. The 392 and SRT models are due in the first half of 2027.
More Under the Hood
On the Rumble Bee SRT, Direct Connection replaces the stock 2.4-liter supercharger with a 3.0-liter twin-screw unit. The truck makes 680 pound-feet of torque in stock form. That bigger blower is meant to lift its power, though the SEMA release gives a target rather than a measured result.
For the other build, a supercharger kit brings the 5.7-liter HEMI’s target above 600 hp. Power runs through an eight-speed automatic, with a 3.92 rear axle ratio and a Ridetech suspension kit. Full-time four-wheel drive stays, while Burnout Mode lets the driver choose rear-wheel drive.
Ceramic Gray paint and black graphics frame the blue supercharger beneath the clear hood window. Carbon-fiber trim surrounds that opening, and the exhaust exits through custom side sills. All four wheels measure 20 by 10 inches and wear 325/50R20 tires.
The blue theme carries into the leather and suede seats, where it pairs with black. Drivers get a flat-bottom steering wheel, aluminum shift paddles, and a console shifter. Outside, a hard tri-fold cover closes off the bed.
Beyond the Booth
Some of the parts have a path to buyers beyond these show trucks. Ram laid out its Direct Connection upgrade program on August 4, months before SEMA. Each blower kit had a listed price of $10,995, plus the cost to fit it.
The program also covers the Rumble Bee 392, whose kit targets more than 700 hp. Buyers can add a Magnaflow exhaust on its own or pair it with the blower. Those exhaust kits range from $1,599 to $2,399, plus labor, based on the truck’s engine.
For owners who want a lower stance, the Ridetech package drops the front by one inch and the rear by three. Its shocks offer 24 damping settings, and Ram listed an expected price of $4,590 before installation.
There is a warranty condition for buyers who add boost. Under Ram’s August terms, an ASE-certified Mopar technician must fit the blower kit to keep the original five-year, 60,000-mile limited powertrain warranty.
