19+ 6.7 COMMON RAIL CUMMINS PRECISION PLUS REMAN LONG BLOCK

19+ 6.7 Common Rail Cummins Precision Plus Reman Long Block

Our Precision Plus 6.7 Cummins Long Blocks for 2019+ models come fully assembled, including the oil pan, rear crank seal, front cover and crank seal, and oil filter housing, along with our Reman Cylinder Head. 

To address common issues found in 2019+ engines, we utilize components from the more reliable 2018 and older models. These older platforms have a superior track record of reliability compared to the newer engines. By replacing the hydraulic roller lifter setup with solid flat tappets and adjustable rockers, we enhance both reliability and performance. Depending on the year selected, we will use 2019-2020 or 2021-2024 front covers and timing gear housings. The older platform allows for seamless integration, as everything bolts in the same way, and ensures more readily available and less expensive parts down the road. We use NON CGI blocks to rebuild 19+ long blocks.

Key Features:

• Comprehensive Inspection: Disassembled, crack checked, inspected, and all threaded holes tapped, blasted, and cleaned before machining.
• Precision Machining: CNC blueprinted, bored, honed, and deck surfaced. Each crank is checked for straightness and size and repaired as needed.
• Thorough Cleaning: Blocks are cleaned and inspected to double-check our machining processes. We measure all bearing clearances, piston-to-wall clearance, piston protrusion, deck, and hone surface. All pistons and rods are double-checked for proper spec and ring gaps corrected as needed.
• Controlled Assembly: Assembled in a clean room by skilled technicians, ensuring top quality.
• Precision Cylinder Heads: Disassembled, crack-checked, with stock seats replaced by extra-large heavy-duty valve seats. CNC precision valve job performed with new seat and guide machine. Meticulously cleaned, inspected, assembled, and pressure-checked.
