Still trying to find the limit on our 10R140 1,000+hp model, so lets add Nitrous Express to the program.

As we prepare for the first start of O-Line V3, lets recap what caused us to be in this postion from last fall.

While everyone sees the finished product, they rarely see the late nights, spreadsheets, measurements, fabrication, testing, troubleshooting, and team meetings that happen behind the scenes.

The shop has been running full speed as we push toward first startup of Fast72 build and O-Line. Every person in the building is doing their part to make it happen.

We're hoping tonight is the night. 👀🔥

Stay tuned... the first fire-up is coming.

The 68RFE will always be our backbone.

Before the 10-speeds, before the new platforms, before the dealer network stretched across the country, there was the 68RFE.

It's the transmission that put WP Developments on the map.

Years of testing, failure analysis, engineering, racing, broken parts, late nights, and relentless development turned the 68RFE from one of the most criticized transmissions in the diesel world into a platform capable of setting records and hauling hundreds of thousands of miles.

Today our 10R140, 10L1000, Allison, and other programs continue to grow, but the 68RFE remains the foundation of who we are. It's where we learned, where we innovated, and where we proved what WP Developments was capable of.

Every new product we release carries the knowledge gained from pushing this platform further than most thought possible.

The 68RFE isn't just another transmission to us.

It's the reason we're here.

And no matter how much we grow, it'll always be part of our story

Our intern from last summer, Edge isn’t even 20 years old yet and he’s going up against the best at Ultimate Callout Challenge this weekend. He’s not only racing the truck, Edge mostly built the whole thing himself!

UCC crunch time is in full swing. 😅

We've been going nonstop for days between customer builds, R&D projects, and customers rolling into town getting ready for UCC.

One thing that's pretty cool to see is our former summer intern, Edge, back in the shop working on his own UCC truck. Watching him go from helping around the shop to competing on one of diesel's biggest stages is exactly what this industry is all about.

We're proud to have Edge and so many other WP customers representing our brand at UCC this year. Whether it's in the transmission, converter, wiring, tuning, or tech support—we're invested in your success.

Like always, you won't find us sitting on the sidelines. We'll be right there in the pits turning wrenches, troubleshooting problems, and helping our customers however we can.
