Window Cranks – Rail Style for GM (to 1948)

This billet aluminum window crank set is designed to fit GM vehicles up to 1948, featuring the distinctive "rail" style arm for a period-correct appearance with modern performance. Machined from 6061-T6 aluminum and polished to a brilliant finish, these cranks offer a clean, refined upgrade over factory pieces.

Each handle is ergonomically shaped for smooth window operation and includes adapter bushings to ensure a secure fit on most common GM spline patterns. The rail styling matches Billet Specialties’ other interior accessories for a consistent, coordinated look.
