Keep the diesel family clear
Duramax includes different engine families and applications. A 3.0L inquiry and a 6.6L inquiry need separate review. GM’s L8T 6.6L is a gasoline engine and is not a Duramax replacement.

Assembly & scope
Confirm whether the offer is a long block, another assembly level or a rebuild of your engine. Accessories, injectors, turbo equipment, controls and installation are included only when stated.
Core & freight
Confirm whether exchange is required and whether a deposit is included or separate. A core must match the purchased engine and be rebuildable to receive credit. Freight and unloading arrangements are confirmed for the order.
Read core requirements →Schedule & warranty
Agree on the build or supply schedule and the written coverage for your exact order. Inspection, parts availability and confirmed scope affect timing. Review the oil, maintenance and warranty requirements before use.
Review warranty information →Questions before you commit
Can I order from the model name alone?
No. Send the VIN and engine identifiers. Model year and displacement alone do not confirm the exact replacement.
Is every engine shown ready to ship?
No. A guide describes an inquiry path. Current stock, build acceptance, price and lead time are confirmed for your specific order before payment.
Can I get installation help?
Ask about installation at our East Texas shop. The engine, installation labor, supporting repairs and vehicle transport must be itemized for your job. Schedule before bringing a vehicle.
What if there is no matching catalog product?
Call or send your application details. Product-name searches can miss a supplier or engine-code listing. We confirm the available assembly or rebuild path rather than substituting a similar-looking product.
