Classic 1955-1957 Chevys

If you're updating your classic Chevy, you'll love the late-model convenience of electric windows. Our power window kits are easy to install, and they make conversion a snap.


These kits are complete and include chrome switches and stainless-steel flexible wire conduits. They use rugged GM-style motors. In all cases, the front door units are straight bolt-in conversions. On two-door sedans and hardtops, you'll need to drill two holes for the quarter glass regulator. The template is provided.


Please note that our GM switches are not exactly like the original parts and are not designed for "original" restorations. Original switches require polarity-reversing relay packs. We have those packs available, so please call us for details.
