Torque Plate Duramax

This ICT Billet torque plate is a crucial tool for professional engine builders and enthusiasts performing precision machining on Duramax diesel engine blocks. Designed for boring and honing cylinders, this 2-inch thick billet aluminum plate simulates the stress of a torqued cylinder head, ensuring a perfectly round bore for optimal piston and ring seating. This process is essential for maximizing engine performance and longevity, especially in high-performance or rebuilt Duramax engines. Crafted in Wichita, Kansas, from aerospace-grade, USA-produced billet aluminum, this torque plate is built for durability and precision. It features 4.15-inch cylinder bore holes, making it compatible with a wide range of Duramax turbo diesel engine blocks, including LB7, LLY, LBZ, LMM, LGH, and L5P models. The robust construction helps prevent bore distortion during machining, leading to a more accurate and consistent cylinder finish. Using a torque plate during the boring and honing process helps account for the slight distortions that occur when the cylinder heads are bolted to the block. By mimicking these forces, the torque plate ensures that the cylinders are perfectly round once the heads are installed, which is critical for proper ring seal, reduced oil consumption, and improved power output. This tool is an investment for anyone serious about Duramax engine building.
