| PROFORM valve spring tools cover the job from teardown to final setup. Valve spring compressors include on-engine stud-mount models for 3/8 and 7/16 studs, a shaft-mount design for small block Chrysler, heavy-duty manual clamp styles, and a pneumatic adjustable-arm unit for high-volume head work. Spring testers run from 300 to 1,000 lb in analog, mini, and digital versions reading down to 2 lb increments, and height micrometers — including a tall model for beehive springs — dial in installed height to 0.005 inch. Built for engine builders who check their work. |
