Texas Motorworx Race Team
We field a SPEC TT/6100 truck in the Best In the Desert series. The race truck is one truck — but the calibration and durability lessons it produces cross over to every customer build that leaves our shop.
The Engineering Insight Loop
Most race programs in the off-road industry exist to sell race-trim parts. Ours exists to develop calibration data that crosses into the customer trucks we build at the shop. Race-pace desert miles teach calibration lessons you cannot learn on a Texas back road — the difference between a great-tuning shock and a mediocre one only shows up at speed and only after 30+ hours of cumulative high-speed time.
That data comes home with us after every event. The bypass shock we run on the race truck informs the rear bypass we spec on a customer Gen 3 Raptor. The Deaver leaf rate we develop for SPEC TT shows up in the F-250 builds we deliver to ranch owners across Texas. The calibration is the moat.
SPEC TT / 6100
SPEC TT (also called Class 6100 in BITD) is a class for production-based race trucks running a regulated set of components — primarily a stock-displacement V8, factory frame, and a tightly defined suspension package. The class is designed to keep the chassis closer to a real production truck than the unlimited Trophy Truck class, which makes the calibration lessons directly applicable to customer builds.
Our truck is built around a Ford Raptor frame with a King 3.0 / FOX 3.0 shock package, a Method 17" wheel and 35"–37" tire setup, and a fab-built bumper and cage system that meets BITD safety regs. We run a Yokohama Geolandar-A/T sometimes; we run BFG Mud-Terrain T/A KM3 most of the time.
Best In the Desert
Best In the Desert is the premier off-road race series in the western U.S. — Vegas to Reno (the longest off-road race in North America), the Mint 400, the Silver State 300, and the Parker 400 are all BITD events. SPEC TT and 6100 trucks race across the same courses as Trophy Trucks, just with regulated power and chassis specs.
The series is famously brutal on equipment. Vegas to Reno alone covers ~550 miles of high-speed desert on a single day, and trucks regularly accumulate 8+ hours of race-pace running time in a single event. That's the duty cycle that produces calibration data nothing else can match.
Three Lessons That Change Every Customer Build
- 01
Rear axle composure beats front travel
Customers arrive obsessed with front travel. But the limit at race pace isn't front travel — it's the rear axle's ability to keep up. We now match every rear bypass shock and leaf rate to the front package, instead of letting it come from a parts catalog.
- 02
Rebound matters more than compression
Most DIY tuners focus on compression damping. Race miles teach you that on rough terrain at speed, the limit is rebound — how fast the shock recovers. Every customer truck now has rebound spec'd specifically rather than coming pre-tuned.
- 03
Heat management is engineering
After 30+ minutes of race-pace running, even a King 3.0 heats meaningfully and the damping curve shifts. We size reservoirs and shock cooling for the truck's expected duty cycle now — not for the cheapest install.
