HD Adjustable Piston Vise

The PROFORM HD Adjustable Piston Vise is a heavy-duty workshop tool engineered for serious engine builders, mechanics, and automotive enthusiasts who need reliable clamping during piston and cylinder head work. Whether you're rebuilding a small-block or big-block engine, installing custom pistons, or performing precision machine work, this adjustable vise provides the stable, non-marring grip essential for protecting expensive components during critical assembly operations. Built for professional and home shop applications, it eliminates the risk of damage that standard bench vises can inflict on finished engine parts.

This piston vise features adjustable clamping surfaces that accommodate various piston sizes and geometries without gouging or scoring soft aluminum alloys and coatings. The heavy-duty cast iron construction weighs 14.32 pounds and measures 7.5 x 7 x 15 inches, providing solid mass and footprint stability during torque-intensive operations. The precision-engineered jaw adjustment mechanism allows fine-tuning of clamping pressure, enabling technicians to secure components firmly while maintaining absolute safety for finished surfaces—critical when working with modern coated or hardened pistons where even minor contact damage can compromise engine reliability.

Professional engine builders and rebuilders rely on this vise for honing cylinder bores, installing piston rings, and performing detailed machine work where part integrity cannot be compromised. It's equally valuable for vintage restoration shops handling irreplaceable or period-correct components. The adjustable design makes it adaptable across multiple engine platforms—from small-displacement four-cylinder mills to large-displacement V8 applications—making it a versatile addition to any serious automotive workshop where precision and part protection directly impact engine performance and longevity. For anyone investing in quality machine work or rebuilds, this PROFORM vise delivers the dependable clamping control that separates professional results from costly mistakes.
