Ram TRX Specs: Every Confirmed Number for Both Trucks
The TRX spec sheet is scattered across two different trucks four model years apart, and most listings mix them up. This is the confirmed set for each, with the gaps marked as gaps.
The confirmed numbers for these two trucks live in different eras, different SRT charters, and in the 2027 truck's case, a spec sheet that is still half-blank because the truck has only been shipping since last August. Treat any listing or forum post that merges them into one table as wrong on its face. Below are the two blocks separately, with every gap marked as a gap instead of guessed at.
This matters more than it sounds like it should. A private-party seller advertising a "2021 TRX, 777 horsepower" either does not know what they have or is hoping you do not. The 702-hp truck and the 777-hp truck are two different vehicles built four model years apart, and the number on the window sticker is one of the fastest ways to catch a bad listing before you drive an hour to look at it.
2021-2024 Ram 1500 TRX: confirmed specs
This is the original TRX, built for a little over three model years before Ram paused the nameplate to relaunch it under the returning SRT badge.
| Spec | Figure |
|---|---|
| Engine | 6.2L supercharged HEMI V8 |
| Horsepower | 702 hp |
| Torque | 650 lb-ft |
| 0-60 mph | 4.5 seconds |
| Transmission | TorqueFlite 8-speed automatic |
| Max tow rating | 8,100 lb |
| Max payload | 1,310 lb |
| Production window | December 2020 through February 2024 |
| Assembly plant | Sterling Heights Assembly Plant (SHAP), Michigan |
Every one of those numbers held across the full four-model-year run. Ram did not publish a mid-cycle power bump or a revised tow rating for the 2021-2024 Ram 1500 TRX the way some competitors do with running changes; a 2021 and a 2024 share the same drivetrain numbers on paper. What changed year to year was trim content, colors, and available packages, not the figures in this table.
If you are shopping this generation, the used market has already sorted itself by year. Recent live-listing averages on this site put a 2021 TRX at roughly $69,500, a 2022 around $75,900, a 2023 near $84,900, and a 2024 close to $94,600, all across a meaningful sample of active listings. Mileage and condition move any individual truck well off those averages, but the year-over-year climb tells you the last-model-year trucks are pricing close to new. For a deeper look at how those numbers break down and what actually drives a truck above or below the average, see the used Ram TRX buying guide and the live market breakdown.
2027 Ram SRT TRX: confirmed specs
The 2027 truck is the first launch of the relaunched SRT division, not a refresh of the outgoing TRX trim. It uses the same basic engine architecture as the original truck, tuned harder.
| Spec | Figure |
|---|---|
| Engine | 6.2L supercharged HEMI V8 |
| Horsepower | 777 hp |
| Torque | 680 lb-ft |
| Starting MSRP | $99,995 |
| Destination charge | $2,595 |
| Production start | August 3, 2026 |
| Assembly plant | Sterling Heights Assembly Plant (SHAP), Michigan |
That is 75 more horsepower and 30 more lb-ft than the 2021-2024 truck made, out of the same displacement and the same supercharged layout, at the same plant. We break down what that power difference actually feels like and where it likely comes from in Ram TRX horsepower: 702 vs 777 and what the extra 75 actually does.
What is not published yet for the 2027 truck
Here is the part most spec pages skip past, and exactly the part this page exists to call out.
- 0-60 mph time: not published. Anyone quoting a number for the 2027 SRT TRX right now is estimating, not reporting.
- EPA fuel economy: not published.
- Max tow rating: not published.
- Max payload rating: not published.
These are not oversights on our part. Ram has not released them for the 2027 Ram SRT TRX as of this writing, and a truck that has been in customer hands for roughly two weeks has not accumulated the kind of independent testing that would fill in a 0-60 number you could trust either. When those figures do get published, or when a credible third-party test posts a real-world acceleration run, this page gets updated. Until then, the honest answer is that the cell is empty, not that it is close to the old truck's 4.5 seconds. More power and more torque do not automatically mean a faster truck once you account for unknown gearing, unknown curb weight, and unknown tire spec, all of which affect 0-60 more than the horsepower number alone.
The used-market data tells a similar story from the buying side: 2027 SRT TRX listings are averaging around $110,300 across roughly 200 live listings, which is consistent with a truck still selling close to sticker with limited used supply, but that is a market observation, not a performance spec. For everything we do and do not know about this launch so far, see [2027 Ram SRT TRX: what actually changed, and what nobody knows yet](/news/2027-ram-srt-trx-what actually changed).
Why these two spec sheets get merged so often
Both trucks wear a TRX badge, both run a 6.2L supercharged HEMI, and both were built at the same Michigan plant, so it is an easy mistake to make even for people not trying to mislead anyone. Listing sites that auto-populate specs from a decoded VIN sometimes pull the wrong generation's power figure entirely, especially in the gap after the 2024 model year ended production and before 2027 inventory showed up in volume.
The tell is usually the horsepower number. If a listing says 777 hp on a truck titled as a 2021-2024 model year, that is either a typo or a description copied from the wrong template. If it says 702 hp on anything titled 2027, same problem in reverse. Cross-check the horsepower figure against the model year before you cross-check anything else.
How this compares to the field
Both TRX generations compete against a different kind of stock truck than most buyers cross-shop against on paper. The Ram 1500 RHO uses a twin-turbo inline-six instead of the supercharged V8, which is a genuinely different approach to the same off-road-performance-truck brief, and we lay out how that changes the ownership case in TRX vs RHO: the honest comparison. Against Ford's competing truck, the comparison runs on different axes entirely, covered in TRX vs Raptor: an honest comparison of two very different trucks.
The short version
- 2021-2024 Ram 1500 TRX: 702 hp, 650 lb-ft, 4.5-second 0-60, 8-speed automatic, 8,100 lb max tow, 1,310 lb max payload, built December 2020 to February 2024 at SHAP. All confirmed, all consistent across every model year of the run.
- 2027 Ram SRT TRX: 777 hp, 680 lb-ft, $99,995 starting MSRP plus $2,595 destination, production started August 3, 2026 at SHAP. 0-60, EPA economy, tow rating, and payload rating are not published yet, full stop.
- If a listing mixes a 777-hp figure with a 2021-2024 model year, or a 702-hp figure with a 2027 model year, walk away from that listing or ask the seller to correct the VIN decode before you take anything else in it at face value.
