Well we are officially calling it, we will not be attending UCC / 72Fast race this year after all.

With no 6.7 block back from the machine shop still, and being absolutely swamped with work the last few months with record sales and a fast growing transmission program we have decided that given what we have now we would not be competitive by simply throwing it back together with the 300k stock 5.9 and no testing we would only be wasting our time and everyone else's.

We know the 72Fast class isn't just a flash in the pan either and we're still gonna continue building the single cab and be ready for the next one ( hopefully this fall?)

That all being said we hope to pick the block up this week and get the 6.7 motor back and together in the coming weeks , and get this little red wagon back on the road and to some local tracks for shakedown passes soon!

Gone Fishin!

Another solid truck back in the shop for a great returning customer. This clean 2006 Ram came in after the original injectors finally gave up after nearly 20 years of service.

We installed a fresh set of S&S Diesel Motorsport New Body Torque Master injectors to get this Cummins running right again and ready for many more miles ahead.

This truck is also equipped with one of our 600HP Street/Strip 48RE transmissions — built in-house with proven parts to handle real power while still being street friendly and dependable. 👌

It’s always awesome seeing customers come back and continue upgrading trucks they’ve owned and cared for over the years instead of replacing them. Solid trucks deserve quality parts and quality work.
