Premium Quality Parts

Manufacturing Since 1973

ATL Diesel supplies aftermarket diesel engine parts built to OEM quality standards. We serve commercial trucks, heavy equipment, and industrial machinery. We stock new and remanufactured parts for Caterpillar, Cummins, Detroit Diesel, International, Mack, Volvo, and Paccar engines. Our inventory covers cylinder heads, camshafts, cam followers, rebuild kits, overhaul kits, gasket sets, pistons, liners, and more. We carry parts from trusted suppliers including PAI Industries and Interstate McBee, and we manufacture our own line of ATL-branded parts as well.

But unlike most suppliers, we also remanufacture in-house. We've been doing it for 50 years. That means you're not just buying off a shelf from a reseller. You're buying from a team that builds and knows these parts.

Our team has over 100 years of combined experience across all major engine makes and models. Faster answers, fewer mistakes, less downtime.

We're family-owned and based in Dallas, TX. Call us at (940) 286-7626 or email sales@atldiesel.com to find the parts you need.
