The '''Ram 1500 TRX''' is a high-performance variant of the fifth-generation [[Ram 1500 (DT)]] [[full-size pickup truck]], produced by the [[Ram Trucks]] division of [[Stellantis]]. The '''TRX''' name was based on the '''Ram Rebel TRX''' concept that was shown at the 2016 [[State Fair of Texas]] as an engineering, design and consumer-interest study.<ref>{{Cite web |last=Weiss |first=C.C. |date=October 4, 2016 |title=Ram kicks the dirt up with 575-hp Rebel TRX concept pickup |url=https://newatlas.com/ram-rebel-trx-concept/45741/ |access-date=August 16, 2018 |publisher=newatlas}}</ref> Following consumer feedback, the company announced on June 1, 2018, that it would place the truck into production for the 2021 model year.<ref>{{Cite web |last=Priddle |first=Alisa |date=July 21, 2018 |title=BREAKING: Mike Manley Named New FCA CEO Amid Marchionne Health Crisis |url=https://www.motortrend.com/news/sergio-marchionne-out-at-fca-months-ahead-of-planned-retirement/ |access-date=August 16, 2018 |publisher=motortrend}}</ref><ref>{{Cite web |last=Butler |first=Zach |date=June 1, 2018 |title=The Ram TRX Is a Go: FCA Confirms 575+ HP Ram and a New Mid-Size Truck Are Coming (News) |url=https://www.tfltruck.com/2018/06/ram-trx-fca-five-year-plan/ |access-date=August 16, 2018 |publisher=tfltruck}}</ref>
The original 702 HP TRX was produced during the 2021 through 2024 model years. It was discontinued after the 2024 model year because it couldn't be modified to meet tougher automotive emissions standards, and the company's shift towards electrification, involving the eventual discontinuation of the 6.2L, 6.4L (except for the Ram HD trucks) and 5.7L Hemi engines altogether, being replaced by the 3.0L Hurricane engine. The last special edition TRX was the Ram 1500 TRX Final Edition. The last Ram 1500 TRX was produced on February 16th 2024.
A similar truck, the Ram 1500 RHO was introduced, but it is not a direct successor to the TRX because it uses a different and less powerful engine, the Hurricane. The model year was cut short because of RAM launching 2025 trucks 7 months earlier than their usual model year release date. However, in late July 2025, Stellantis CEO Antonio Filosa has officially confirmed that the TRX will be returning for the 2026 model year.<ref>{{Cite web |last=Weiss |first=C.C. |date=July 31, 2025 |title= THE BEAST IS BACK: 2026 RAM 1500 TRX RETURNS WITH HELLCAT FURY |url= https://www.diehlofmoon.com/the-beast-is-back-2026-ram-1500-trx-returns-with-hellcat-fury/#:~:text=After%20a%20brief%20hiatus%2C%20the,liter%20Hellcat%20V8%20with%20it |access-date= August 12, 2025}}</ref> The Ram 1500 TRX has returned on January 1, 2026 as a 2027 model, with a redesign and a horsepower upgrade to {{Convert|777|hp|kW PS|0|abbr=on}}.

== Ram Rebel TRX concept == [[File:Ram-rebel-trx-concept-cars-coffee-fca-2017.jpg|thumb|Ram Rebel TRX concept]] The non-production modifications of the concept prototype include 37-inch tires mounted on [[Mopar]] 18-inch bead-lock wheels featuring body color matched rings, two full size spare wheels and tires in a bed mount configuration also featuring a lockable unit housing a jack, tow strap, and room for more tools. Other production departures include a six inch wider track with extended fenders to cover the wider wheel base, giving the truck an hourglass look when viewed from above, LED clearance lights, a tire rack mounted LED light bar, five inch side exhaust integrated into protective rock rails, skid plates, a 6.2-liter supercharged HEMI V8 engine based on the popular [[Chrysler Hemi engine#6.2 Hellcat|Hellcat]] featured in [[Dodge Charger (LX/LD)#Charger SRT Hellcat|Dodge Chargers]], [[Dodge Challenger#2015 model year (facelift)|Challengers]], and the [[Jeep Grand Cherokee#Fourth generation (WK2; 2011)|Jeep Grand Cherokee]] Trackhawk, but detuned for the truck application to 575 horsepower mated to a TorqueFlite [[ZF 8HP transmission|8HP70]] transmission and a BorgWarner 44-45 transfer case. The drivetrain features four modes from which to choose: Normal, Wet/Snow, Off-road and Baja. The rear axle is a Dynatrac Pro 60 and the vehicle also features an electronic [[Locking differential#Selectable lockers MRT|axle locker]] available in all modes. The modified suspension is built onto a stock "DS" Series [[Ram Pickup|Ram]] platform 1500 frame. The link coil based suspension is upgraded with performance springs, 2.5-inch King Racing Shocks and feature a 40% increase in travel to 13" front and rear from the standard 9".
The interior also features multiple deviations from the stock [[Ram Pickup#2017 changes|Ram Rebel 1500]] including faux suede inserts in the seats, "sport-sanctioned lateral support upper bolsters with embroidered logos", six point harnesses, cloth door pulls, a console shifter, a rotary selector for the various drive modes, an anodized steering wheel with accent stitching, [[Semi-automatic transmission|paddle shifters]], a tool bag featuring TRX labeling, carbon fiber and red metal inlays, a camera mount near the rearview mirror, and a sport bar to which the six point harnesses mount. The concept also features a non-production shade of "Header Red" that was applied in thirty different coats.<ref>{{Cite web |last=Miller |first=Robert Scott |date=August 15, 2018 |title=Inside Design: 2016 Ram Rebel TRX Concept: The Ultimate Performance Offroad Ram... |url=https://moparinsiders.com/inside-design-2016-ram-rebel-trx-concept/ |publisher=5thgenrams}}</ref><ref>{{Cite web |last=Mcearchen |first=Sam |date=October 4, 2016 |title=The Ram Rebel TRX Concept Has 30 Coats Of Paint On It |url=http://fcauthority.com/2016/10/the-ram-rebel-trx-concept-has-30-coats-of-paint-on-it/ |publisher=fcauthority}}</ref>
=== Reception === After the unveiling of the concept at the 2016 Texas State Fair, multiple online media published positive reactions:
"For now, all we can do is dream about owning one of these beasts as it is still just a concept vehicle."<ref>{{Cite web |last=Feigen |first=Martin |date=2016 |title=Ram Rebel TRX Stuns But Will They Build It |url=https://artofgears.com/2016/09/30/ram-rebel-trx-stuns-but-will-they-build-it/ |publisher=artofgears}}</ref>

== Production history == In February 2018, Jared Belfour, citing unnamed sources, reported that two Ram Rebel models based on the Ram Rebel TRX concept will be produced. A base version featuring a new version of the naturally aspirated 426 cubic inch (7.0L) HEMI engine and the optional supercharged 6.2L HEMI engine as well as a 2021 release date.<ref>{{Cite web |last=Belfour |first=Jared |date=February 24, 2018 |title=EXCLUSIVE: Ram Rebel TRX will have a choice of 2 engine options! 5thGenRams has inside information about the engine lineup for the 2021 Ram Rebel TRX. |url=https://5thgenrams.com/exclusive-ram-rebel-trx-engine-lineup-confirmed/ |publisher=5thgenrams}}</ref>
Later that same year in April, also citing unnamed sources, 5th Gen Rams reported that the two engine options will be associated with different names where the "Ram Rebel TR" features the naturally aspirated 426 cid HEMI engine and the "Ram Rebel TRX" features the supercharged 6.2L HEMI engine. Unlike the concept, the supercharged 6.2L HEMI will not be detuned to {{convert|575|hp|kW PS|0|abbr=on}}, but is reported to put out the same 707 horsepower as the engines used in the Dodge Challenger SRT Hellcats, Charger SRT Hellcats, and the Jeep Grand Cherokee Trackhawk.<ref>{{Cite web |last=Belfour |first=Jared |date=April 5, 2018 |title=EXCLUSIVE: 7.0L V8 Rebel and 6.2 SC Rebel will have different names 5thGenRams learns a few more details on the upcoming Rebel variants |url=https://5thgenrams.com/exclusive-7-0l-v8-rebel-and-6-2-sc-rebel-will-have-different-names/ |publisher=5thgenrams}}</ref>
However, the 2019 Dodge Challenger SRT Hellcat Redeye was announced in August that same year which featured essentially the same engine from the Dodge Challenger SRT Demon with variations on the air intake dropping the Redeye's horsepower rating to 797 from the Demon's 808 (also, the 2019 non-Redeye Dodge Challenger SRT Hellcat features airflow improvements raising its horsepower rating to 717 over the prior year's 707).<ref>{{Cite web |last=Miller |first=Robert Scott |date=August 14, 2018 |title=Challenger SRT HELLCAT - More Tech, More Horsepower, Lower Price: The Original Top Cat Gets A Makeover For 2019... |url=https://moparinsiders.com/challenger-srt-hellcat-more-tech-more-horsepower-lower-price/ |publisher=moparinsiders}}</ref>
The "Hellephant" Mopar crate engine scheduled for 2019 release unveiled at the 2018 SEMA (Specialty Equipment Manufacturer's Association) Show, a 7.0-liter supercharged {{convert|1,000|hp|kW PS|0}}, {{convert|950|lbft|Nm kgm|0|abbr=on}} engine.<ref>{{Cite web |last=Miller |first=Robert |date=October 30, 2018 |title='Hellephant' in the Room: Mopar Stampedes Into SEMA With 1,000-Horsepower: Supercharged Mopar Crate Motor Makes 1,000-Horsepower... |url=https://moparinsiders.com/hellephant-in-the-room-mopar-stampedes-into-sema-with-1000-horsepower/ |publisher=moparinsiders}}</ref> exceeds the characteristics of the Redeye engine, but is also not expected to be part of the production Ram Rebel TRX configuration (when asked, "members of the Mopar team" responded "absolutely not" regarding whether or not the Hellephant engine was being considered for ''any'' street applications, which would necessarily rule out inclusion of the production Ram rebel TRX).<ref>{{Cite web |last=Rall |first=Patrick |date=October 30, 2018 |title=426 Hellephant crate engine packs 1,000 horsepower |url=https://www.allpar.com/news/2018/10/426-hellephant-crate-engine-packs-1000-horsepower-42739 |publisher=allpar}}</ref>

Over the 3-year model run, Ram released a [[Special edition|limited-edition]] model of the TRX for every model year, sometimes even multiple. Here is the list of them: 2021 - Ram TRX Launch Edition (702 Made) 2022 - Ram TRX Ignition Edition (1,003 Made), Ram TRX Sandblast Edition (1,202) 2023 - Ram TRX Lunar Edition (~1,000 Made), Ram TRX Havoc Edition (~1,500 Made), 2024 - Ram TRX Final Edition (4,000 Made), Ram TRX Special Edition (380? made - same as final edition without the final-edition center armrest badging and splash screen). All of these limited-edition models (except for the launch and final editions) were released mid-model year. Oddly, the base model TRX is more rare than some of these.{{citation needed|reason=It would be unlikely for a base model to be rarer than special editions, as it is usually the opposite. Please provide a source if this is true.|date=January 2026}} There is 1707 total base TRXs made, 664 in 2021, 825 in 2022, 218 in 2023.{{citation needed|date=February 2026}}
===2026 revival=== On January 1, 2026, Ram unveiled the new 2027 Ram 1500 TRX. The new truck's horsepower has been bumped up to {{Convert|777|hp|kW PS|0|abbr=on}} and {{Convert|680|lbft|Nm|0|abbr=on}} of torque to make it more competitive with the Ford F-150 Raptor R, and also includes graphics previously used on the Ram 2500 Power Wagon and SRT badges, with the new name being the '''Ram 1500 SRT TRX'''. The truck's new vinyl design is also for to celebrate the relaunch of the [[Street and Racing Technology]] (SRT) division. On the same day, the [[Dodge Power Wagon#2026 update|2027 Ram 2500 Power Wagon]] now features the 6.7L [[Cummins ISB|Cummins ''ISB'']] diesel engine.<ref>{{Cite web|url=https://www.caranddriver.com/news/a69887837/2027-ram-1500-srt-trx-revealed/|website=CarAndDriver|title=Ram's TRX Supertruck Is Back with SRT Badges and a 777-HP V-8|date=January 1, 2026|access-date=January 1, 2026}}</ref>
The TRX also got a new special limited edition package to celebrate its return, known as the ''Bloodshot Night'' Edition.<ref>{{Cite web|url=https://moparinsiders.com/srt-amps-up-the-trx-with-new-bloodshot-night-edition/|website=Mopar Insiders|title=SRT amps up the TRX with new Bloodshot Night edition|date=January 1, 2026|access-date=January 1, 2026}}</ref>

== Criticism == The [[American Council for an Energy-Efficient Economy]] ranked the Ram 1500 TRX the worst-performing mass-market vehicle for 2021, 2022, and 2023 on its score "based on an environmental damage index that reflects the cost to human health from pollution associated with vehicle tailpipe emissions, vehicle manufacturing and disposal, and the production and distribution of auto fuel and electricity."<ref>{{Cite web |title=GreenerCars 2023: Efficiency and Weight—Not Just Electric vs. Gas—Shape Environmental Impact |url=https://www.aceee.org/press-release/2023/02/greenercars-2023-efficiency-and-weight-not-just-electric-vs-gas-shape |access-date=November 6, 2023 |website=The American Council for an Energy-Efficient Economy}}</ref><ref>{{Cite news |last=Gozelany |first=Jim |title=Dirty Baker's Dozen: The 13 Environmentally 'Meanest' Vehicles For 2021 |work=Forbes |url=https://www.forbes.com/sites/jimgorzelany/2021/02/24/dirty-bakers-dozen-the-13-environmentally-meanest-vehicles-for-2021/?sh=1843cf8c165b |access-date=November 6, 2023}}</ref>
