Highlights:
- Complete Remanufactured Long Block: Fully rebuilt to D&J Precision Machine specifications for a reliable replacement engine.
- Precision Machined: CNC blueprinted, bored, honed, and deck surfaced for precise cylinder geometry and proper piston fit. Each crankshaft is checked for straightness and size and repaired as needed.
- New OEM-Spec Tier 1 Pistons and Rings: Provides a high-quality piston and ring package for proper fit, sealing, and consistent engine performance.
- Upgraded L5P Oil Cooler: Improves engine oil cooling to help maintain lower oil temperatures and reduce the risk of piston cracking and related engine failure.
- Remanufactured Cylinder Heads: Resurfaced and fitted with recut valve seats and new valves for proper sealing and reliable valve operation. The upgraded L5P top-hat valve stem seal design helps prevent valve seal failure and improve long-term durability.
- Upgraded ARP Head Studs and MLS Head Gaskets: Provides increased clamping strength and reliable cylinder sealing to help address common LML head gasket failure.
- Pinned Oil Pump: Secures the oil pump to help prevent pump rotation and maintain consistent oil pressure.
- Keyed Crankshaft and Camshaft: Addresses a known failure point by providing positive mechanical retention between the shaft and gear, helping prevent unwanted movement and related component failure.
- New Bearings and Thrust Washers: Restores proper internal clearances and supports reliable engine operation.
- New Valves: New high-quality valves provide reliable sealing and consistent valve operation for improved long-term durability and performance.
- New Valve Springs: Restores proper valvetrain operation and performance.
- Rocker Boxes, Valve Covers and Intake Manifolds Included: Reduces component transfer and installation time for a more complete replacement package.
- Complete Rotating Assembly: Includes the harmonic balancer, flywheel, flex plate, flex plate washer, and new mounting hardware.
- Precision Assembly: Critical engine dimensions and clearances are verified throughout the build for consistent quality.
- In-House RMC Engine Testing: Before shipment, every engine is mounted on D&J's dynamic engine test system and rotated at speed while sensors measure oil pump pressure and volume, cylinder compression, and cooling system integrity. This lets D&J catch internal issues in-house, before the engine ever reaches your truck.
- Built for Everyday Use: Designed to provide reliable performance for everyday driving, and towing applications.
