BorgWarner 48-13 Full-Time Active Transfer Case & Axle Engineering

TorqueFlite 8HP75 & BorgWarner 48-13 Transfer Case

Beneath the twin-turbocharged 3.0L Hurricane High-Output inline-six, power routes through a TorqueFlite 8HP75 eight-speed automatic transmission calibrated for high-speed off-road thermal endurance. Torque is distributed continuously between the front and rear wheels via a BorgWarner 48-13 full-time active transfer case featuring an upgraded low-range gear ratio of 2.64:1 for technical rock crawling. Unlike part-time four-wheel-drive pickups that bind on dry pavement, the BorgWarner 48-13 utilizes an electromagnetically controlled wet multi-plate clutch pack to vary front-to-rear torque split dynamically according to steering angle, wheel slip, and selected drive mode (Auto, Tow, Mud/Sand, Rock, Baja, Sport, Snow, and Custom).

Dana 60 Full-Floating Rear Axle & Suspension Geometry

At the rear axle, the 2025 Ram 1500 RHO deploys a Dana 60 full-floating solid rear axle with an electronic locking differential and a 3.92:1 final drive ratio. The rear axle hop damper—mounted directly between the axle housing and frame crossmember—suppresses driveline tramping under hard acceleration across loose desert washboards. Forged aluminum front upper and lower control arms expand track width by 6.0 inches over a standard Ram 1500 while accommodating 13.0 inches of front suspension travel and 14.0 inches of five-link coil-sprung rear travel. Combined with 35-inch Goodyear Wrangler Territory All-Terrain tires (325/65R18) mounted on optional 18-inch beadlock-capable wheels, the chassis maintains 11.8 inches of running ground clearance and 32.0 inches of certified water fording depth.

Cabin Architecture, Equipment Groups & Exterior Finishes

Inside the Crew Cab 5-foot-7-inch box configuration, the Level 1 Equipment Group (9,995 dollars option package) adds 12-way power heated, ventilated, and massaging Natura Plus leather front bucket seats, a 14.5-inch Uconnect 5 vertical touchscreen, a 10.25-inch front passenger interactive display, a 12.3-inch digital gauge cluster, a full-color Head-Up Display (HUD), dual wireless charging pads, and a 19-speaker 900-watt Harman Kardon premium audio system. Buyers can configure seven factory exterior finishes in our 2025 Ram 1500 RHO colors and OEM paint code visualizer. With a starting base MSRP of $69,995 (71,990 dollars including 1,995 dollars destination charge), the Ram RHO undercuts the outgoing 96,585 dollars Ram TRX by 26,590 dollars while delivering a 150-pound lighter front end and an 8,380-pound SAE J2807 rho towing capacity.

Frequently Asked Questions About the 2025 Ram 1500 RHO

Authoritative answers regarding powertrain output, octane derating, towing compliance, and chassis dimensions.

What engine powers the 2025 Ram 1500 RHO?

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.

Does the Ram RHO completely replace the Ram TRX?

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 lower starting MSRP.

What is the towing capacity and payload of the Ram RHO?

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.

Can the 2025 Ram RHO run on 87 octane regular fuel?

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.

What suspension system does the Ram RHO use?

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.
