Fresh off the bench, oringed Cummins cylinder heads built for guys who run their trucks hard and don't want to worry about head gasket failure. Machined and oringed in house at Tru Cylinder Head and Machine, backed by Powerhouse Diesel.

If you're pushing power past stock, an oringed head is cheap insurance. We cut the orings, machine the deck flat, and check everything before it leaves the shop.

Got a set of heads that need this done right? Send us a message or drop them off.

SPE Motorsport 20+ turbo and the first Pro Form Fabrication 23+ mini cradle kit in existence. Not the first one we installed. The first one built, period.

It hooks hard. It should have left harder, and that is on us, not the parts. We already know what we are changing before the next hook.

That is the upside of doing this in house. Every pass teaches us something that goes right back into what we build for customers.

Got questions on the cradle kit or the 20+? Drop them below and we will answer every one.

Ever wondered what a 6.0 looks like while we bore it? Every hole gets cut to spec, measured, and cut again. The base of every build is machine work.

Saturday night at the Claiborne county fair and our shop truck got hooked to a sled for the first time ever.

5th out of 24 trucks.

This is not a show truck. It sits in our lot all week and works. Tuned in house on a 175/30 and a KC turbo. No mystery budget build, just a clean tune and parts we actually sell and stand behind.

First time out and it held its own against trucks built to do nothing but pull. We will be back.

Who wants to see what we change before the next one?
