Rumble Bee SRT Rips with 777 Horsepower and a Targeted Top Speed of 170 mph
Source: Stellantis Media — March 27, 2026
Highlights:
- Rumble Bee SRT features the most powerful V-8 engine ever offered in a production pickup: 777 hp from a 6.2-liter supercharged HEMI®
- SRT delivers the most track-capable production pickup in the world — 170 mph targeted top speed, 11.6-second quarter mile, 3.4-second 0-60 mph
- Rumble Bee 392 is the first Ram 1500 to offer the 392-cu.-in. (6.4-liter) HEMI V-8
- Exclusive Quad Cab/short bed combination with 13-inch wheelbase reduction for improved handling and proportions
- 88 inches wide, 219.5 inches long — heroic, unduplicated muscle truck proportions
- 325/40R22 tires on 22x12-in. wheels on SRT — widest combo since the Dodge Viper
- Up to 8,890 lbs towing capacity / up to 1,160 lbs payload
- Four variants: Rumble Bee (395 hp), Rumble Bee 392 (470 hp), Rumble Bee 392 Track Pack, Rumble Bee SRT (777 hp)
- 5.7L launches late 2026; 392 and SRT arrive first half of 2027
The 2027 Ram 1500 Rumble Bee lineup is confirmed in "Muscle Runs Deep," a short film hosted by Tim Kuniskis, head of American Brands, SRT Performance and North America Marketing at Stellantis.
Ram is tying its participation in the NASCAR Truck Series with an all-new subsegment of muscle trucks featuring three HEMI®-powered variants. The top-level Rumble Bee SRT crushes 0-60 mph in 3.4 seconds, rips through the quarter-mile in 11.6 seconds at 116 mph, and rockets to a targeted top speed of 170 mph — setting a record as the most powerful, quickest, and fastest V-8-powered production pickup ever.
"Somehow, the idea of muscle trucks was labeled unnecessary, but since that describes so many products that captivated enthusiast's hearts, minds and wallets, Ram is going all-in — pushing for the last tenth with a full-range of Rumble Bee Muscle Trucks." — Tim Kuniskis
Twenty years ago, Ram discontinued the original muscle truck — the 8.4-liter V-10, 500-horsepower Ram 1500 SRT10 "Viper truck." Now, Ram is back.

Engineering
The engineering team's primary goal: make Rumble Bee handle "untrucklike" — without sacrificing truck capability.
- Frame shortened 13 inches — reduces flex by 10%, creates exclusive Quad Cab/short bed combo
- Track width 6.8 inches wider up front, 7 inches wider in the rear vs. standard Ram 1500
- Rumble Bee / 392: Steel SLA suspension, Bilstein monotube performance shocks, robust front and rear stabilizer bars
- 392 Track Pack / SRT: Standard air suspension (lowered an additional 1.5 in.), Bilstein Damptronic Sky semi-active dual-valve shocks
- 392 Track Pack / SRT: 0.89g lateral grip — 20%+ improvement over base Rumble Bee
Brakes:
- Rumble Bee / 392: 14.9-in. front vented discs, two-piston calipers / 14.8-in. rear discs
- 392 Track Pack / SRT: 16.1-in. front rotors with six-piston Brembo calipers
Drive Modes:
- Rumble Bee / 392: Auto, Sport, Snow, Tow, Custom (5 modes)
- 392 Track Pack / SRT: Adds Track and Valet (7 modes total)
392 Track Pack and SRT also feature dedicated launch control — line up, drop into Drive, hit the launch button, mash brake and throttle, wait for the green light, and hang on.
Aerodynamics (392 Track Pack & SRT)
At 170 mph, over 1,000 lbs of force impacts the front end. Ram engineers generate 192 lbs of positive downforce through four key elements:
- 4.5-in. front splitter (SMC construction) — divides airflow, generates front downforce
- Front aero shield (PET thermoplastic) — links splitter to cradle, adds downforce
- Brake-cooling ducts — reduce brake temps by 30%+ depending on speed and conditions
- 80-mm rear tailgate spoiler (TPO construction, 8 mounting points) — balances rear downforce at high speed
- Optional hard tri-fold tonneau cover — structural rigidity manages airflow, adds rear stability
Exterior Design
- Overall length: 219.5 in. | Width: 88 in. (Quad Cab / short bed)
- Widebody fenders, bodycolor flares and bumpers, unique smaller performance mirrors
- Premium LED lighting front and rear; optional bedside graphics
