Why Choose Us
Built on Reliability
We're not a chain shop. We're local, we know diesel, and we stand behind every job — from light-duty pickups to heavy equipment to marine engines.
🚛

We Come to You

Equipment down in the field or broke down on the road? Our fully-equipped service trucks get to you fast across Northeast Kansas.

🔧

Diesel Specialists

Diesel is all we do. From light-duty pickups to heavy equipment, our experience is focused entirely on diesel — not split across every make and model that rolls through a bay.

📦

Authorized Dealer Parts

Dealer accounts with Warren Diesel, FASS, KC Turbo, B&W Hitches, Fleetguard, Jasper, and more. Quality parts sourced through dealer accounts and local truck dealership relationships.

🏭

OEM Sourcing Too

Strong relationships with local truck dealerships means we can source OEM parts at competitive pricing — not just aftermarket.

Marine Diesel

Tug boats and barges along the Missouri River — we service marine diesel engines dockside or on the water. Not a service you'll find at most shops.
