CT525 Crankshaft Adapter

The CT525 Crankshaft Adapter from Winters is a precision mechanical coupling solution designed for builders and technicians who need to mate a Winters crankshaft assembly to GM LS-series engine platforms. This adapter addresses compatibility issues in high-performance and custom engine builds where OEM crankshaft geometry differs from modern LS platform standards. It is ideal for vintage-to-modern engine swaps and race engine builds.

Constructed from steel, the CT525 is designed to deliver durability under mechanical stress. The finish provides corrosion resistance, protecting against oxidation in various environments, while maintaining dimensional stability critical to crankshaft alignment. The precision-engineered coupling geometry ensures minimal runout and vibration, which is essential for maintaining proper harmonic balancer function.

Engine builders, machine shops, and serious automotive enthusiasts will benefit from this adapter when undertaking complex drivetrain conversions. Its compact dimensions allow for easy integration into tight engine compartments without adding unnecessary weight, making it a valuable tool for those working on custom engine applications.
