At its core sits a Callies forged steel crankshaft, chosen for its exceptional strength and ability to withstand high stress over time. All new pistons, rings, bearings, and gaskets are installed, using OEM or equivalent components to ensure consistent quality and performance. Cylinder heads are fully remanufactured with new seats, guides, valves, and stem seals, then resurfaced and magnafluxed to verify strength and prevent future issues. Rockers and pushrods are preset to exact factory specifications, helping the engine run smoothly right from the first start. Advanced Rottler machining technology is used throughout the process to achieve precise tolerances.
