Manufactured by Hot Rods and identified by manufacturer and vendor part number 4424-1, this stroker crankshaft includes proven Hot Rods connecting rods, top-end bearings, and crankshaft webs. The assembly is factory assembled and trued to OEM specifications, helping provide a reliable drop-in replacement that typically requires no engine modification. Its increased stroke is designed to support greater displacement and horsepower while retaining the stock piston in most applications.
The Hot Rods 4424-1 is CNC machined and dynamically balanced to accommodate its increased stroke. Precision-manufactured gears meet DIN Class 9 or higher quality standards for consistent operation. The crankshaft is also fully rebuildable using genuine Hot Rods connecting rods and bearings, supporting long-term serviceability and simplifying future engine maintenance. For additional displacement and horsepower potential, it can be paired with Cylinder Works Big Bore cylinders where application-specific compatibility permits.
Verify the exact vehicle model, year, and engine configuration before ordering. Professional installation is recommended to ensure proper crankshaft fitment, engine assembly, and final balancing.
