Give Your Tired 6.7L A Piston Designed To Burn Cleaner

A 6.7L Cummins that has gone tired is hard to live with, especially when the truck still has years of work left in it. The DFC Diesel KORE Series Speed of Air long block gives 2007.5-2018 RAM 2500 and 3500 owners a way back without the budget of a new crate engine. What sets this one apart from a standard KORE build is the pistons. They are Speed of Air Hyperformance pistons, which have precise, CNC machined dimples on top called turbulators, plus a thermal barrier coating on the crowns and an anti friction coating on the skirts. According to DFC and Speed of Air, those dimples help the flame front burn closer to the cool walls of the combustion chamber, which improves combustion efficiency. They say that can mean better fuel mileage, more torque and horsepower, and better pulling power, though results will vary by truck and how it is driven. The rest of the engine is the KORE Series build you would expect, with Rottler machined tolerances better than OEM, head studs, Total Seal gapless rings, and improved gasket sealing in the spots where these engines commonly leak. It arrives as a short block with the cylinder head already on, so the hardest part of the rebuild is done before it reaches your shop. For a third gen or fourth gen Cummins that has to keep earning its keep, this is a smart step up from a like for like replacement.

Turbulator Pistons And Head Studs Inside A Rottler Machined Cummins Long Block

The DFC Diesel KORE6707518SOALB is a remanufactured long block built for 2007.5-2018 Dodge RAM 2500 and 3500 trucks with the 6.7L Cummins, listed for use with the G56 manual transmission and the 68RFE automatic transmission. It uses Speed of Air Hyperformance pistons, which have patented turbulator indentations CNC machined into the piston top to exacting tolerances under ISO 9001 quality standards. Speed of Air says these indentations create a thinner, well attached boundary layer between the air fuel mixture, its flame front, and the combustion chamber walls, which raises combustion efficiency. The pistons also carry a thermal barrier coating on the crowns and an anti friction coating on the skirts. The rest of the engine follows DFC's KORE Series process, machined on Rottler equipment to tolerances better than OEM, with all new rings, bearings, gaskets, seals, valves, springs, hardened seats, stem seals, and cast guides. It comes standard with head studs, Total Seal gapless piston rings, and improved gasket sealing in common leak areas. The engine ships as a complete short block assembly with the cylinder head, and the page lists a top end gasket kit as included while stating that the injector return line seal kit and the turbocharger gasket kit are not. It is built in an ISO 9001:2015 certified facility and backed by a 1 year, unlimited mileage manufacturer warranty.
