OUR SERVICES

Our team of professionals will perform fluid flush and fills, oil changes, and tire maintenance.

ENGINE OIL

We do oil changes for semis and large trucks, done right and done fast. Keep your big rig’s engine slick, strong, and ready to haul hard mile after mile.

TRANSMISSION FLUID

Fresh fluid prevents costly failures, keeps shifts smooth, and helps your transmission last longer. Regular service keeps your rig working hard.

TIRE SERVICE

Good tires keep you rolling, your load steady, and your crew moving. From fixing leaks to mounting new rubber, solid tire work means fewer breakdowns.

FUEL FILTERS

On-site fuel filter changes are available to help keep your semi or rig running and reduce downtime.

AIR FILTERS

Clean air filters keep your engine breathing right, fuel burning clean, and power where it belongs — mile after mile, year after year.

REAR-END FLUID

Proper rear-end fluid shields your differential, reduces heat and wear, and ensures reliable power transfer, keeping your rig hauling heavy loads safely.

WIPERS

New windshield wipers cut through rain, snow, and grime, giving you clear vision, safer drives, and confidence behind the wheel in any weather.

FUEL-WATER SEPARATION FILTERS

Oil and water separation filter service keeps your fuel clean, prevents corrosion, and protects your engine on every haul.

As a proud division of Southwest Truck Parts, we’re built on a strong technical foundation. That connection gives us access to skilled technicians, real-world know-how, and the ability to offer more services to help keep trucks on the road.

Stopped in Pratt for an oil and tire service on my semi. Saw the place from Caseys parking lot. It was really convenient while I was on the road.
