Making friends in the diesel industry is what it is all about at the end of the day! If you have brought your truck to us you probably have heard us talk to you about products for all your fuel needs.

We got to see the real ins and outs of what it is all about at their facility and how their products are made from the bottom up and you might just think it’s as simple as throwing some big injectors in your truck to make power, but there’s a method to the madness!

Thank you so much for having us out to your facility and we look forward to building our relationship alongside the best in the biz! 👏

We are all guilty of getting on our trucks every once in awhile🤐🤨 don’t make the same mistake Jon did and blow a freeze plug out the side of the head 🫡😅

Did you do the DCR conversion from on your 6.7 powerstroke yet or are you lame?

Highly recommend doing this on your truck or else you’re going to be having a lot more tears and glitter coming into your fuel system 🪩💃

Call to get on the schedule! 💪🫡 774-627-8231📞

A built “Fummins” has entered the dyno 🤘🏻🦅

This ford had a 12 valve that we did some upgrades to make some pretty decent power in👏🏻

Upgraded delivery valves , governor spring kit , stage 3 injectors all from as well as a bigger turbo setup to make a healthy 500hp and 1000 torque!

We always look forward to fun builds in the shop now that the nice weather is here 🇺🇸
