This Chevy 2500 Duramax Is Getting Some Serious Work! 💪

This Duramax is in the shop for a major refresh, and we're doing it the right way from the inside out.

We're installing brand-new head gaskets and cylinder head studs, but we're not stopping there.

We're also ditching the factory CP4 injection pump and converting this truck to a CP3 injection pump setup—a popular upgrade for Duramax owners looking for a proven alternative to the CP4 fuel system.

This isn't a quick parts swap. It's detailed, precision work that requires the right equipment, knowledge, and real Duramax experience.

When your Duramax needs more than basic maintenance, bring it to the shop that knows these trucks inside and out.

We've been busy doing big jobs and making Duramax diesels even better!

Servicing a timing chain is a big job on any vehicle. On a 3.0L Duramax? It’s a whole different level.

This is the kind of complex repair many shops simply aren’t equipped or experienced enough to take on, and even some dealerships would rather not tackle it.

At Southern Performance Diesel, Duramax trucks are what we do. From routine maintenance and diagnostics to major engine repairs and complex jobs like 3.0L Duramax timing chain service, we have the experience, equipment, and knowledge to handle the jobs other shops turn away.

If you own a 3.0L Duramax and need a shop that understands your diesel from the inside out, bring it to the specialists.
