Ram TRX vs Ram RHO: The Honest Comparison
The RHO replaced the TRX at the same $69,995 base price with 162 fewer horsepower. On every published capability figure except power, it is the more capable truck.
The Ram 1500 RHO replaced the TRX. It costs the same money to the dollar, it is slower on paper by a tenth of a second, and it makes 162 fewer horsepower.
That combination is why the question gets asked constantly and answered badly. The short version: the RHO is not a cheaper TRX, and it is not a worse one. It is a different trade, and which way the trade falls depends entirely on what you actually do with the truck.
Here is what is verifiable, with the sources named.
The numbers
| Ram 1500 TRX | Ram 1500 RHO | |
|---|---|---|
| Years | 2021–2024 | 2025–present |
| Engine | 6.2L supercharged HEMI V8 | 3.0L Hurricane H.O. twin-turbo I6 |
| Power | 702 hp | 540 hp |
| Torque | 650 lb-ft | 521 lb-ft |
| 0–60 mph (claimed) | 4.5 sec | 4.6 sec |
| Quarter mile (claimed) | 12.9 sec @ 108 mph | 13.1 sec @ 105 mph |
| Top speed | 118 mph | 118 mph |
| Max towing | 8,100 lb | 8,380 lb |
| Max payload | 1,310 lb | 1,520 lb |
| EPA combined | 12 mpg | 15 mpg |
| Rear suspension travel | >13 in | up to 14 in |
| Ground clearance | 11.8 in | 11.8 in |
| Wading depth | 32 in | 32 in |
| Shocks | Bilstein Black Hawk e2 | Bilstein Black Hawk e2 |
| Base MSRP at launch | $69,995 | $69,995 |
Power and drivetrain figures are Stellantis', from the TRX release of 17 August 2020 and the RHO release of 25 April 2024. Fuel economy is EPA, from fueleconomy.gov. Both trucks launched at the same $69,995 base — the TRX with $1,695 destination in 2021, the RHO with $1,995 in 2025.
What actually changed
Less than the engine bay suggests. Both trucks sit on the DT chassis. Both run Bilstein Black Hawk e2 adaptive dampers. Both use a Dana 60 rear axle with an electronic locker. Ground clearance is identical at 11.8 inches, wading depth is identical at 32 inches, and both roll on 35-inch rubber in the same 325/65R18 size.
What changed is the engine and everything the engine implies. The TRX's supercharged 6.2 and the RHO's twin-turbo 3.0 six share nothing that touches air, fuel or spark. That has a practical consequence for owners: parts do not carry over. S&B sells two entirely separate intake part numbers for these trucks. Exhaust, tuning and forced-induction hardware are separate ecosystems. Suspension, armour, lighting, recovery and bed gear frequently do cross over — our own mod database lists parts from ICON and Foutz that state fitment for both — but never assume it. Read the fitment.
The part nobody leads with
The RHO out-works the TRX.
It tows 280 lb more, carries 210 lb more payload, has an inch more rear travel, and returns 3 mpg better combined — 15 against 12. On a truck that a lot of people bought as a truck, that is not a rounding error. Over 15,000 miles a year, 12 to 15 mpg is roughly 250 gallons.
The TRX's answer is 162 horsepower and the noise that comes with it, and that is a real answer. Nobody buys a supercharged V8 on a spreadsheet.
Be careful with the 0–60 numbers
Manufacturer claims put these trucks a tenth apart, 4.5 against 4.6. Treat that as close to meaningless.
When Car and Driver instrumented a TRX in October 2020, it ran 3.7 seconds to 60 and 12.3 at 110 in the quarter — comfortably quicker than Ram's own 4.5 and 12.9 claims. Manufacturer numbers on this truck were conservative.
We do not have a verified instrumented figure for the RHO. A 4.4-second time is widely repeated online, but we could not confirm it against a primary source, so we are not printing it as fact. What that means practically: the real gap between these trucks is probably wider than the claimed figures suggest, but we cannot yet tell you by how much. Anyone stating the tested gap with confidence is guessing.
Which one
Buy the TRX if the engine is the point. It is the only one of the two with a supercharged V8, it is finished — 2021 to 2024, no more coming — and the used market is where it now lives.
Buy the RHO if you tow, haul, or drive it enough that 3 mpg matters. It is the better truck at truck things, it is the one still in production with a factory warranty, and it gives up nothing in ground clearance, wading depth or damper hardware.
One thing that is not a reason either way: the idea that the RHO is a downgrade because the V8 left. On every published capability figure except power, it is the more capable vehicle.
What we could not verify
Stated plainly, because an empty field is a true statement and an invented one is not:
- RHO instrumented 0–60 and quarter mile. No primary source we could reach.
- RHO curb weight. Sources disagree — 6,283 lb, 6,294 lb and 6,541 lb all
circulate. We are not averaging them.
- RHO front suspension travel and approach/breakover/departure angles.
Widely reported by secondary sites, absent from the Stellantis release.
- RHO transfer case and rear axle ratio. The release confirms a Dana 60 with
an e-locker but gives no ratio.
- Current-model-year RHO MSRP. $69,995, $73,340 and $73,795 all appear
across dealer and aggregator sites; ramtrucks.com blocks automated checking. The launch figure above is the one we can source.
Ram's own consumer pages could not be read directly for this piece — they refuse automated requests — so every manufacturer figure here comes from the Stellantis newsroom releases named above, and every fuel-economy figure from the EPA. If you find one of these numbers contradicted by a source we should be reading, tell us and we will correct it.
