S&S Cycle 84-99 BT 4-3/8in Torque Plate

S&S Cycle is well-known for their high-performance engine components, and this torque plate is a prime example of their focus on precision. This 4-3/8 inch torque plate is specifically designed for 1984-1999 Big Twin (BT) engines. Its main job is to simulate the stress that cylinders endure when the engine is fully assembled and torqued down, but it does this during the critical honing process. By honing the cylinders while this plate is installed, you ensure they maintain their intended dimensions much better once the engine is actually running.

Using this torque plate means the cylinders won't distort out of round when the heads and cylinders are bolted down. This leads to a more accurate bore and better sealing for your piston rings, which is crucial for engine performance and longevity. It’s a well-built piece that helps achieve a more precise build, especially when you're aiming for optimal power and reliability from your Big Twin engine.
