HD Adjustable Piston Vise

The PROFORM HD Adjustable Piston Vise is a heavy-duty work vise engineered for mechanics, machinists, and automotive technicians who require precision holding of engine components and piston assemblies. Built with aluminum construction and red anodized finish, this adjustable piston vise accommodates pistons up to 4.5 inches, making it ideal for small-block and mid-size engine work across classic restoration, performance tuning, and general machine shop applications.

The adjustable jaw design allows operators to secure different piston geometries and sizes without requiring multiple vises, reducing inventory and workspace requirements. At 14.32 pounds with compact dimensions of 7.5 x 7 x 15 inches, this piston vise provides substantial clamping force while maintaining portability across workbenches or mobile service environments. The aluminum construction resists corrosion, an essential feature in shops where coolant spray and humidity are constant conditions, while the red anodized finish provides durable surface protection and visibility on crowded work surfaces.

This vise is built for technicians performing engine teardown, piston ring installation, pin removal, and component inspection where stable, controlled clamping prevents damage to precision-finished surfaces. The heavy-duty construction handles the repetitive clamping cycles and moderate side loads typical of engine assembly and disassembly work. Whether working on a single restoration project or managing high-volume engine service, the PROFORM piston vise delivers consistent, repeatable holding without marring sensitive piston skirts or rod journals.
