DD13 — Mid-Range Heavy-Duty Engine

13-litre platform for regional haul, vocational, and construction applications

DETROIT DIESEL · DD13

DD13 — 12.8L Inline-6 Diesel

12.8L · 2010–Present · Freightliner, Western Star, Thomas Built Buses

The DD13 is Detroit’s 13-litre inline-six designed for regional haul, vocational, and severe-service duty cycles. Power outputs range from approximately 370 to 450 horsepower. The DD13 shares core architecture with the DD15 but is optimized for stop-and-go conditions, construction fleets, and applications where the full displacement of the DD15 is not required. Also specified in certain school and transit bus platforms.

DETROIT DIESEL · DD13 GEN5

DD13 Gen 5 — Updated Emissions Architecture

12.8L · 2021–Present · Freightliner, Western Star

The Gen 5 DD13 aligns the 13-litre platform with current EPA and GHG Phase 2 standards while delivering improved fuel economy in regional and vocational duty cycles. When requesting a DD13, specify whether you require the earlier EPA 2010/2013-era configuration or the current Generation 5 to ensure the correct ECM, aftertreatment system, and wiring harness compatibility.

Series 60 — Legacy Heavy-Duty Platform

Widely rebuilt and still in active service across North America — extensive used and remanufactured supply

DETROIT DIESEL · SERIES 60

Series 60 — 12.7L DDEC-Controlled Diesel

12.7L · 1987–2011 · Freightliner, Kenworth, Peterbilt, Volvo, Mack

The Detroit Series 60 12.7L is one of the most prevalent legacy heavy-duty engines in North America. DDEC (Detroit Diesel Electronic Controls) versions span DDEC II through DDEC VI. Engine serial number, DDEC generation, and emissions tier (Pre-2002, 2002, 2007 EPA) are critical to accurate parts matching. The Series 60 remains widely rebuilt and remanufactured due to the large installed base and ongoing demand from owner-operators and fleet operators running pre-EGR trucks.

DETROIT DIESEL · SERIES 60 14L

Series 60 — 14.0L Displacement Variant

14.0L · 1994–2011 · Freightliner, Kenworth, Peterbilt

The Series 60 14.0L is the higher-displacement variant of Detroit’s flagship legacy inline-six, producing power outputs up to approximately 515 horsepower. It shares the same DDEC electronic control architecture as the 12.7L but with increased bore and stroke for greater torque output. Commonly found in heavy-haul fleets and favoured for high-gross-weight applications. Specify displacement clearly when requesting sourcing — the 12.7 and 14.0 share the same engine family but are not interchangeable.

What to Include in Your Detroit Diesel Inquiry

Engine Model

DD15, DD13, Series 60 12.7L, Series 60 14.0L, or DD15 Gen 5

Engine Serial Number

Found on the engine dataplate. Critical for DD-series ECM matching and Series 60 DDEC generation identification.

Emissions Tier (Series 60)

Pre-2002, 2002 EPA, or 2007 EPA (EGR). Determines EGR, aftertreatment, and DDEC version compatibility.

Truck Application

Make, model, and year of the truck the engine is being sourced for. Compatibility must be verified — engine family alone does not confirm fitment.

Destination

Country, city, and postal code. Required for shipping cost estimation and export documentation.

Compatibility Notice: Detroit Diesel engines are installed across multiple truck OEMs and chassis configurations. Fitment compatibility with a specific truck must be verified using the truck VIN and engine serial data before purchase. Canada Parts Exports does not claim compatibility based on engine brand or model family alone. Our sourcing team will assist with verification as part of the inquiry process.
