What Factors Affect Diesel Engine Cost?
Engine Size (Displacement)
Larger engines (12-15L heavy-duty) cost more than smaller engines (6.6-6.7L light-duty) due to more material, more components, and more machining time.
Brand & Model
Some engines are more expensive to remanufacture due to parts cost, complexity, or availability. Caterpillar and Cummins heavy-duty engines tend to be at the higher end.
Application Type
Commercial/fleet engines may require additional certifications, emissions compliance, or specific configurations that affect pricing.
Warranty Coverage
Longer and more comprehensive warranties reflect higher quality remanufacturing standards. Our 1-year unlimited mileage warranty is included in the price.
Core Return Credit
Returning your old engine core can reduce costs by $500-$2,000+. Our core return program makes this easy.
Market Conditions
Supply chain factors, raw material costs, and demand fluctuations can affect pricing. We maintain large inventory to keep prices stable.
