<Tr> <Td> SRT - 10 </Td> <Td> 2004 - 2006 </Td> <Td> 8.3 L (505 cu in) Viper V10 </Td> <Td> 510 hp (380 kW) </Td> <Td> 535 lb ⋅ ft (725 N ⋅ m) </Td> </Tr> <P> Models built after January 1, 2007 offered a new 6.7 L Cummins turbo diesel introduced as an option in 2500 / 3500 models replacing the 5.9 L. It produced 350 hp (261 kW) and 650 lb ⋅ ft (881 N ⋅ m). Unlike the 5.9 L which was backed by the 4 - speed 48RE Transmission, the 6.7 L was equipped with the new 6 - speed 68RFE transmission . </P> <P> 2005 was the last year for the first version of the 5.7 L (345 cu in) Hemi V8 . 2006 half - ton models offered the Multi-Displacement System Hemi V8 engine that also became available in Chrysler and Dodge sedans . This engine featured the same performance but had a cylinder - deactivating feature enabled under light loads to increase fuel economy by 3 MPG city and 4 MPG hwy . This new Hemi still delivered 345 hp (257 kW) and 375 lb ⋅ ft (508 N ⋅ m). </P> <P> For the 2003 model year, AAM axles replaced the Dana Corp axles . In the front all 2500 and 3500 trucks were 9.25 - inch with 33 spline axles . The rear options for the 2500 and 3500 were the AAM (often referred to as "corporate") 10.5" and 11.5 ". Rear axle shafts are 30 spline . The rear 11.5" has a gear ratio "carrier split" at 3.73 and numerically higher, but the General Motors AAM axles used a different carrier spacing preventing installation of a Chrysler carrier into some GM axles, but the GM carrier can be installed in the Chrysler axle if a ring gear spacer is installed . Strength is similar to their earlier Dana 70 and 80 counterparts . Direct comparisons are difficult as the axles are made with completely different metallurgy . </P>
