BD Diesel DJPLB100080 Precision Plus Long Block Engine 6.7L Cummins 2019-2020

The BD Diesel DJPLB100080 Precision Plus Long Block is a fully remanufactured 6.7L Cummins engine assembly engineered for exceptional durability in street, towing, and heavy-duty work truck applications. Built by DandJ Precision Machine, every long block is CNC-machined, balanced, and blueprinted to exacting tolerances for maximum efficiency and long-term reliability.

A key upgrade in this long block is the replacement of the hydraulic roller lifters found in 2019+ Cummins engines with solid flat tappets and adjustable rockers, directly eliminating a well-known failure point in these engines. Year-specific front covers and timing gear housings are used to ensure seamless, drop-in compatibility with 2019–2020 model year applications.

Key Features:

• Rated up to 600 HP — Designed for demanding work and towing applications; high-horsepower tuning is not recommended for sustained heavy towing use
• Precision CNC Machining — Fully blueprinted, bored, honed, and deck-surfaced for consistent power output and structural integrity
• Solid Flat Tappet Upgrade — Hydraulic roller lifters replaced with solid flat tappets and adjustable rockers to eliminate common failure points found in 2019+ models
• Remanufactured Cylinder Head — Features extra-large valve seats, a high-precision CNC valve job, and pressure-tested for maximum durability
• Year-Specific Components — Utilizes 2019–2020 front covers and timing gear housings for seamless OEM-style fitment
• Fully Assembled and Pre-Lubed — Includes oil pan, front cover, and break-in oil pre-applied for simplified installation and immediate startup readiness
