We’re loading up the crew and heading to Fleece Performance Engineering tomorrow for Cars, Trucks & Coffee!

We’re looking forward to seeing some great trucks and catching up with everyone in the diesel community.

If you’re coming out, be sure to stop by and say hey!

Two minutes. One full hook. Just O-Line doing what it was built to do. 💨

Right now it’s all about seat time, making hooks, learning the truck, and getting better every time we put it on the track.

FP 6.0 gave us another solid pull and plenty to take home and work on. Now we keep dialing it in before our grand finale pull of the year at Diesels in Dark Corners this November.

We’re just getting started. 🤘

A little look at what our truck builder Jacob is running in his own truck 👀

WP Comp Flight 48 paired with a custom WP 17–250 stall bolt-together converter, along with a Clear View external filter kit, remote cooler kit, Motion Raceworks shifter, and AirDog lift pump. Pretty solid setup from one of the guys building these things every day. 🤘

Everything listed is available through WP Developments.

When we say our 10 speeds will have you flying, we meant it 🤣

While the floating trucks may be fake, having a built 10 speed ready to handle whatever you can throw at it is real. Ready to take your 10 speed to the next level? Get yours at https://wp-developments.com/product-category/transmissions/

We can tell you what a WP transmission is built to handle.

Or you can hear it from the racers actually putting them through it.

Hard passes. Real competition. Real world abuse. These are the people pushing the limits and choosing WP to do it.

Don’t just take our word for it. 🏁
