Ultimate Crate Engine Upgrade for Towing and Hauling Applications

When your truck is built to tow, haul, and handle heavy workloads, your engine needs to be just as tough. Over time, stock components wear down, power fades, and reliability starts to become a concern—especially when pushing your 6.7L Cummins to its limits. Instead of gambling on a rebuild or replacing worn-out parts one by one, the BD Diesel Heavy Hauler Long Block gives you a fully assembled, performance-built engine designed specifically for demanding work applications. Built for strength, efficiency, and durability, this long block is the perfect upgrade for serious towing and hauling. One of the biggest improvements in this engine is the D&J Stage 1 High-Performance Cylinder Head. Unlike a stock head, which can struggle with airflow and heat dissipation under load, this version is 5-axis CNC-ported for maximum efficiency. It features oversized heavy-duty intake and exhaust seats, which help the engine breathe better and improve durability in high-stress conditions. Whether you're pulling a loaded trailer up a steep grade or running a tuned setup, this upgraded head ensures smoother power delivery and lower exhaust gas temperatures.

Handles Extreme Applications With Ease

Managing heat is crucial for any towing application, and this engine is built to keep temperatures in check. The custom street/towing camshaft is designed to reduce EGTs by 200-300 degrees, making a huge difference when you're hauling heavy loads over long distances. Lower EGTs mean a more efficient combustion process, helping to improve fuel economy and reduce stress on the turbo and cooling system. If you've ever watched your EGTs climb while towing, you know how important this upgrade can be for both performance and engine longevity. To handle high boost and heavy workloads, BD Diesel reinforces this long block with custom ARP 9/16” head studs. These provide superior head-to-block sealing, preventing head gasket failures that are all too common in high-load applications. Whether you're running a stock turbo or an upgraded setup, these studs help keep everything sealed tight, even under extreme cylinder pressure.

Precision-Engineered Construction with Bolt-On Install

Every engine in the Heavy Hauler series is CNC-machined, fully blueprinted, and assembled with precision to ensure maximum reliability. It includes brand-new internal components, including pistons, bearings, and tappets, eliminating the risk of using worn or questionable parts. Unlike a pieced-together rebuild, this long block is designed to go the distance, delivering stock-like drivability with significantly improved strength and longevity. Installation is made easy with a fully assembled, pre-lubed design that comes ready to drop in. The long block includes an oil pan, front timing cover, and rocker box, so there's no need to hunt down extra components before getting back on the road. Designed as a direct replacement for 2007.5-2012 Ram 6.7L Cummins applications, it eliminates the downtime and uncertainty of a full rebuild, giving you a hassle-free solution with proven performance.
