Since joining forces with @duramaxtuner, we’ve combined our transmission lineup with the DT Series Allison transmissions.

By bringing together the experience, knowledge, and proven build strategies from both teams, we’ve refined the lineup further while maintaining the quality, performance, and reliability our customers expect. After installing and testing these transmissions in-house, we’ve had great success.

Focusing on one lineup also allows us to improve production, availability, and inventory, getting transmissions out the door faster.

Whether your truck is built for towing, street driving, or competition use, these Allison builds are ready to handle it.

Richard K.’s 2021 L5P Duramax came in for the full package. 🙌

We started with our Stage 3 High Flow Bundle Kit, combining key airflow and exhaust upgrades to improve turbo efficiency, throttle response, and spool-up.

Paired with @duramaxtuner Custom Performance ECM and TCM tuning, this setup is capable of gains up to 150 RWHP and 270 lb-ft of torque.

For even more efficiency and reliability, we added a Stealth STR Drop-In VGT Turbo along with our High Flow Turbo Pedestal Kit—boosting flow by over 12%.

To further support performance, our Billet Exhaust Manifolds and Up Pipe Kit replace restrictive factory components with high-flow upgrades.

We also upgraded the fuel system with our L5P Fuel Filter Housing Kit, which increases capacity and extends service intervals.

To finish it off, our Coolant Pipe and Coolant Tank completed the look.

If you’ve received a product from us in the last 5 years that included a machined or precision cut and bent sheet metal part, there’s a 100% chance Terry Compton was involved in getting your order to you.

Terry joined us at our previous DeKalb shop as a 25+ year veteran in the CNC Machine Tool industry after unofficially moonlighting with us for a bit. His guidance and experience have been instrumental in helping build our Machine and Sheet Metal shops and shape our manufacturing capabilities into what they are today. Terry’s warm smile and sense of humor have a way of making even the toughest of problems seem lighter and solutions within reach.

Today we celebrate Terry in his 🎉Retirement🎉!

Enjoy the time with Mary and the grand kids, up at the cabin, out on the sled and cheering on son Spencer (our Fab Shop Supervisor) behind the wheel of our After Hours pull truck!

We’re going to miss you around here! Very thankful you were part of our journey and happy you’re now able to start enjoying the next part of your adventure!
