Designed as a more complete replacement solution for worn or failed LML engines, this long block is completely disassembled, cleaned, inspected, precision-machined, and rebuilt to D\u0026amp;J specifications. The block is CNC blueprinted, bored, honed, and deck-surfaced before being matched with new OEM-spec Tier 1 pistons and rings, while the remanufactured cylinder heads receive new valves, recut valve seats, and D\u0026amp;J's upgraded L5P top-hat valve-stem seal design. The Precision Plus package also addresses several known LML durability concerns with ARP head studs, Tier 1 MLS head gaskets, an upgraded L5P oil cooler, a pinned oil pump, and keyed crankshaft and camshaft retention.\u003c\/p\u003e\n\u003cp\u003eBeyond the upgraded internal components, the Precision Plus is designed to reduce the amount of parts transfer and installation work required during an engine replacement. The package includes rocker assemblies, rocker boxes, valve covers, intake manifold, harmonic balancer, flywheel, and related hardware, along with new bearings, thrust washers, lifters, valve springs, and freeze plugs. Every long block is assembled with critical dimensions and clearances verified throughout the build, then tested in-house on D\u0026amp;J's RMC ETS equipment to verify cylinder compression, cooling system integrity, and oil pump pressure and volume. The result is a professionally remanufactured LML long block built for dependable everyday driving and towing, incorporating upgrades to enhance the engine's durability.\u003c\/p\u003e","brand":"D\u0026J Precision Machine","offers":[{"title":"Default Title","offer_id":67605582020973,"sku":"DJ-DJPLB100111","price":13499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/2487\/2301\/files\/djplb100111_01.jpg?v=1790972692","url":"https:\/\/dieselpowerproducts.com\/products\/d-j-precision-plus-remanufactured-long-block-11-16-gm-6-6l-duramax-lml","provider":"Diesel Power Products","version":"1.0","type":"link"}
