Camburg Engineering
Off-road racing suspension house from Southern California, best known for desert-race-proven control arm and trailing arm kits. Sells a dedicated Kinetik Series control arm and trailing arm kit line for the 2021-2023 Ram 1500 TRX — go here for race-grade suspension components, not body armor or engine work.
Known for: Kinetik Series control arm/trailing arm kits built specifically for the Ram 1500 TRX
Foutz Motorsports
Arizona desert-race shop founded by Greg Foutz, who built the first Ford Raptor Baja 1000 race truck in 2009. Runs a dedicated 2021-2024 Ram TRX product collection (suspension, skid plates, bed organizers). Race-pedigree fabrication shop, primarily a parts brand for TRX rather than an in-house TRX build program.
Known for: Desert-race-pedigree fabricator with a dedicated Ram TRX parts line
Hennessey Performance Engineering
Texas hypercar builder whose Mammoth 1000/1200 packages are the best-known aftermarket TRX upgrade in the country — full engine, supercharger and drivetrain packages installed and dyno-verified at their Sealy facility, with a factory-style warranty. Call them for a turnkey, documented high-horsepower TRX build, not a budget bolt-on.
Known for: Mammoth 1000/1200 TRX packages, 1,000+ hp
SDHQ Off Road (SDHQ Motorsports)
30,000-sq-ft Gilbert, Arizona off-road shop (45 staff) that started as a Ford Super Duty specialist and expanded into full-service builds. Runs a dedicated TRX Builds page showcasing in-house customer builds — go here for a complete, fabricated turnkey TRX build, not a single part.
Known for: In-house, fully fabricated turnkey Ram TRX builds
Underdog Motorsports
Mesa, Arizona off-road install shop with a dedicated Ram off-road parts page selling and installing lift kits, suspension and armor for Ram trucks including the TRX. Team cites over 38 years of combined off-road experience; a solid regional install shop rather than a national parts brand.
Known for: Local install shop for Ram lift/suspension/armor in the Phoenix metro
Premier Performance UT
Utah retail/install shop with a dedicated Ram TRX collection covering ADD Bomber/Stealth Fighter bumpers, Borla/Corsa exhaust and intakes. A parts-and-install storefront rather than a fabrication shop — good for bolt-on armor and exhaust, not custom builds.
Known for: Utah's TRX bumper/exhaust/intake install storefront
Livernois Motorsports & Engineering
Detroit-area late-model Ford/GM/Mopar tuning house (family lineage traces to a 1949 machine shop, current tuning operation dates to around 1999) with a specific PCM-unlock-and-tuner bundle for the 2021-2024 Ram TRX 6.2L Hellcat. Go here for a dyno tune, not body/suspension work.
Known for: PCM unlock + tuner bundle specifically for the 2021-2024 Ram TRX 6.2L
Arrington Performance
Longtime NASCAR-lineage HEMI engine builder (Buddy Arrington racing heritage) that sells crate HEMIs and Magnuson-supercharged builds for Ram 1500/2500 trucks. Their own site shows Magnuson-blown Ram 1500/2500 HEMI customer builds but no Ram TRX-specific work — call for a HEMI crate engine or supercharger build, not a TRX-specific upgrade.
Known for: NASCAR-pedigree crate HEMI engines and Magnuson-supercharged Ram HEMI builds
FAS Motorsports
Florida shop running TRX, F-150 and Raptor street builds out of one facility, with a published TRX supercharger power ladder from 800 to over 1600 whp, installed and calibrated in-house. Go here for a documented, in-shop-tuned high-power TRX build.
Known for: In-house 800-1600+ whp Ram TRX supercharger power ladder
High Horse Performance, Inc. (HHP)
Delaware Gen3 HEMI specialist with a dedicated Ram TRX section covering engine internals, supercharger hardware, fuel systems and in-house dyno tuning. Known in the HEMI drag-race world since 2004; go here for engine-level TRX work, not just bolt-on accessories.
Known for: Dedicated Ram TRX engine/supercharger parts catalog + in-house dyno tuning
Kong Performance
Pennsylvania supercharger shop that CNC-ports Hellcat-based TVS2650 blowers and builds direct-fit throttle bodies for the TRX's 6.2L HEMI. A parts/porting specialist, not a full-service install shop — most TRX owners buy through a dealer network and install elsewhere.
Known for: CNC-ported TVS2650 supercharger upgrades for the TRX's Hellcat engine
Thuren Fabrication
High-desert Oregon suspension fabricator with a dedicated Ram TRX/RHO product collection alongside their long-running Ram 1500 line. Appointment-only facility — call ahead before visiting for install work.
