High-clearance stamped steel bumper paired with Bilstein Black Hawk e2 adaptive dampers providing 13.0 inches of travel and boulder clearance with 35-inch Goodyear Territory MT tires.
The 2025 Ram 1500 RHO introduces the 3.0-liter Hurricane High-Output twin-turbocharged inline-six engine to Stellantis' full-size truck lineup. Generating 540 horsepower at 5,200 RPM and 521 lb-ft of torque at 3,500 RPM, this powertrain replaces the legendary 6.2L supercharged HEMI V8 while shedding critical front-axle mass.
Each bank of three cylinders feeds a low-inertia turbocharger with electronically controlled wastegates. Peak boost pressure tops out at 26.0 PSI (1.79 bar), delivering immediate throttle response at low RPM and sustaining flat torque delivery between 2,500 and 5,500 RPM.
While engineered for 91 minimum and 93 optimal octane, the Hurricane ECU incorporates dual wideband knock sensors capable of retarding ignition timing. On standard 87 octane, output derates to 500 hp and 485 lb-ft without damaging internal components.
Built on a high-strength hydroformed steel chassis, the Ram RHO broadens the front and rear track by 6.0 inches. It pairs Bilstein Black Hawk e2 active dual-valve dampers with 11.8 inches of ground clearance and 35-inch factory Goodyear Territory all-terrain tires.
The system continuously monitors vehicle speed, throttle position, steering angle, and chassis pitch through 100Hz electronic sensors. Independent dual proportional valves adjust rebound and compression damping within milliseconds to absorb desert whoops and prevent bottoming out.
Engineered for technical rock crawling and high-speed dunes, the RHO achieves an approach angle of 31.1 degrees, a breakover angle of 21.9 degrees, and a departure angle of 25.2 degrees. The high-mount air induction system ensures certified water fording up to 32.0 inches.
Under standardized SAE J2807 towing protocols, the 2025 Ram 1500 RHO is certified for a maximum trailer towing capacity of 8,380 pounds and a payload limit of 1,520 pounds. This establishes a 280-pound towing gain over the previous supercharged Ram TRX.

Authoritative answers regarding powertrain output, octane derating, towing compliance, and chassis dimensions.
The 2025 Ram 1500 RHO is powered by a 3.0-liter Hurricane High-Output twin-turbocharged inline-six engine producing 540 horsepower at 5,200 RPM and 521 lb-ft of torque at 3,500 RPM. It features twin low-inertia turbochargers delivering up to 26.0 PSI peak boost.
Yes, Stellantis discontinued the supercharged 6.2L HEMI V8 Ram TRX after the 2024 model year. The Ram RHO succeeds it as Ram's apex high-performance off-road pickup truck, offering nearly identical acceleration, 150 lbs less front-axle weight, improved fuel economy, and a 26,000 USD lower starting MSRP.
Under standardized SAE J2807 tow testing protocols, the 2025 Ram 1500 RHO achieves a maximum certified towing capacity of 8,380 pounds and a maximum payload rating of 1,520 pounds. This provides a 280-pound towing increase over the previous TRX.
Yes. While the Hurricane High-Output engine is calibrated for 91 octane minimum and 93 octane optimal performance, the dual wideband knock sensors automatically retard ignition timing on 87 regular fuel. This derates output by approximately 40 hp and 36 lb-ft without damaging engine internals.
The RHO rides on Bilstein Black Hawk e2 adaptive performance shock absorbers with dual electronic proportional valves and remote nitrogen reservoirs. It provides 11.8 inches of ground clearance with 13.0 inches of front wheel travel and 14.0 inches of rear wheel travel.
