The Honest Take

KNOWN FOR:

The Hellcat-powered Ram. 702hp supercharged 6.2L V8. Bilstein Black Hawk e2 shocks. Factory 35" tires. The truck that started the Raptor R arms race.

Strengths

  • 702hp supercharged V8 - insane
  • Bilstein Black Hawk shocks are excellent
  • Wider track than regular Ram 1500
  • Factory 35" tires from Ram
  • Genuinely fast in any condition

Watch Out For

  • Discontinued after 2024 (RIP)
  • 12 MPG combined fuel economy
  • TRX-specific wheels only - very limited
  • Premium price
  • Heavy for a "performance" truck

Build Categories

Pick the direction you want to take this truck. Each section has wheel styles, colors, and specs that work for that build.

Daily+

Better than stock, daily-able, OEM+ aesthetic

For owners who want their truck to look noticeably upgraded without sacrificing ride quality, gas mileage, or daily usability. Stock-height suspension with cleaner aftermarket wheels and slightly more aggressive tires. The most common build in Texas because most owners drive their truck every day.

  • Wheel sizing: 18-20" diameter, +18 to +44 offset
  • Tire pairing: 33" effective (e.g. 285/65R18 or 285/55R20)
  • Suspension: Stock height OR mild leveling spacer

Wheel styles that work

Clean 5 to 7-spoke designs that mimic OEM aesthetic but with sharper edges and modern finishes. Avoid super-aggressive concave or beadlock-style wheels - they look out of place on a stock-height truck.

Color recommendations by truck color

  • Black truck: Bronze, machined, black, or red accent wheels
  • White truck: Anything works - gloss black, gunmetal, bronze, machined, chrome
  • Red truck: Black, grey, or machined finishes
  • Grey or Silver truck: Anything - most flexible truck color for wheel pairing
  • Blue truck: Machined, black, or grey - neutral wheels let the blue stand out

Off-Road Performance

Beadlock-ready, smaller diameter, serious capability

The build for guys who actually take their truck off-pavement. Smaller diameter wheels (17"-18"), 8.5"-9" wide, conservative offsets, beadlock or beadlock-style wheels, aggressive M/T or hybrid tires.

  • Wheel sizing: 17x8.5 or 18x9, -6 to -12 offset (beadlocks available)
  • Tire pairing: 35x12.50 M/T or hybrid (KO3, Wildpeak, Toyo R/T Trail)
  • Suspension: Quality shock set or factory off-road suspension

Wheel styles that work

Simple spoke patterns, thick construction, beadlock-capable. Avoid anything thin or pretty - it gets destroyed off-road.

Color recommendations by truck color

  • Black truck: Bronze, machined, black, or red accent wheels
  • White truck: Anything works - gloss black, gunmetal, bronze, machined, chrome
  • Red truck: Black, grey, or machined finishes
  • Grey or Silver truck: Anything - most flexible truck color for wheel pairing
  • Blue truck: Machined, black, or grey - neutral wheels let the blue stand out

Upgrade Warnings

Common upgrades that affect other parts. Plan for these before you spend.

If you upgrade: Any suspension modifications

Risk: Factory Bilstein shocks engineered specifically for TRX.

What to do: Don't modify suspension. Wheels and tires only.

If you upgrade: Regular Ram 1500 wheels

Risk: TRX has significantly wider track. Regular Ram wheels won't fit.

What to do: TRX-specific wheels only.

If you upgrade: Supercharger longevity

Risk: Heat is the enemy of superchargers.

What to do: Cooler upgrades, fluid changes, conservative driving in heat. Don't track it.

Frequently Asked Questions

Modify it?

Wheels and tires only. Factory suspension and powertrain are dialed.

Bolt pattern?

5x139.7 but TRX-specific wheels only due to wider track.

TRX vs Raptor R?

TRX (702hp) vs Raptor R (700hp). Very close. TRX has more luxury interior, Raptor R has slight aftermarket advantage.

Worth buying used?

If you find a clean low-mile one, yes. Production ended 2024 - they'll appreciate.
