JS Tools KSM155 Pro Deep Throat Shrinker/Stretcher

The JS Tools KSM155 Foot-Operated Shrinker Stretcher is a premium metal shaping machine built for professionals who demand precision, control, and exceptional finish quality. Made in Sweden, this professional-grade shrinker stretcher is ideal for forming complex curves, flanges, and compound panels in steel or aluminum.

With its large 6-inch throat depth, the KSM155 gives fabricators the reach needed for more advanced sheet metal shaping work. The foot-operated design keeps both hands free to guide the material, while the optimized pedal geometry provides smooth leverage for controlled, fatigue-free operation. The quick-change shrinker and stretcher jaws can be swapped in seconds using the included wrench. Their unique oval-shaped design and super-fine serrations provide excellent grip while reducing marks on the material, helping produce cleaner panels with less finish work.

This machine is an excellent companion to an English wheel or planishing hammer, making it a valuable addition for restoration shops, aircraft builders, hot rod shops, and serious metal shaping professionals. Dedicated jaws are available for steel and aluminum to help achieve the best possible finish quality for each material. The included wheeled base allows the KSM155 to be easily moved around the shop and positioned wherever needed.

Built for elite metalworkers, this tool is trusted in top hot rod and aircraft shops around the world, including Ron Covell, Chip Foose, and Kindig-it Design.
