We have high precision valve spring testers that are ideal for valve springs used in go-kart or snowmobile engines all the way up to nitro injected top fuel engines.

This is an inexpensive tester with full features. The tester has a two-line backlit LCD display of force and length and has deflection compensation for accurate readings at all times. It has a rugged cast-aluminum and steel frame, precision rack and pinion drive with adjustments for wear and convenient hand operation to apply force and adjust length. It includes standard length lock and mechanical overload stops to protect the tester from damage.
