The Allstar Performance Shrinker Stretcher Combo (ALL11023) is a vise or bench-mount metal shrinking and stretching tool built for shaping sheet metal. The kit includes one base and two interchangeable jaws, finished in black and red. The shrinker jaw draws material together to form inside curves, while the stretcher jaw expands material to form outside curves, making the tool useful for shaping fenders, radiator shrouds, and other contoured body panels. The tool ships fully assembled and includes mounting hardware for securing it to a workbench. It is rated to form 8 gauge mild steel, 16 gauge aluminum, and 20 gauge stainless steel.
A manufacturer spec sheet for the ALL11023 is available from Allstar Performance: Allstar Performance Spec Sheet (PDF).
