Frequently asked questions

How much does a Detroit Series 60 12.7L rebuild cost?

Parts alone for a full inframe rebuild on a 12.7L typically run $3,500 to $6,500, depending on the brand and whether you need a head, injectors, or turbo work bundled in. Labor at a shop usually adds $4,000 to $8,000. Owner-operators who do their own work commonly come in around the $5,000 parts mark for a complete inframe-plus-head rebuild.

What's the difference between an inframe kit and an overhaul kit?

An inframe kit (sometimes called an "in-frame" or "in-chassis" kit) is what you need to rebuild the engine without pulling it from the truck. It includes pistons, liners, rings, rod bearings, and gaskets. An overhaul kit adds main bearings, thrust washers, and other components that require the engine to come out of the chassis to install. With-head kits add the cylinder head itself.

How long does a Detroit Series 60 12.7L last between rebuilds?

The 12.7L Series 60 is one of the most durable highway diesels ever built. Well-maintained engines routinely go 800,000 to 1,200,000 miles before a first inframe. Some make it past 1.5 million on the original bottom end. The 14L variant goes even longer.

Is the 12.7L Series 60 the same as the 14L?

No — they share the same architecture but the 14L has a longer stroke and different displacement. Most parts are not interchangeable. If you're shopping for a 14L, see our Detroit Diesel Series 60 14L collection. Always verify the engine serial number before ordering.

Will these parts fit pre-EGR and EGR 12.7L engines?

Many will, but some won't — EGR engines (2002 and later) use different head gaskets, different EGR-specific components, and in some cases different pistons. Always provide your engine serial number when you call so we can match parts to the exact build.

Can ATL help me figure out what I need for a full rebuild?

Yes. Call (940) 286-4144 with your engine serial number and the work you're planning. A tech will walk through the parts list with you and flag anything commonly missed.
