Vastly superior to any other spring, this is the best legal alternative for increased rpm range and total valve train control of your racing Briggs & Stratton Animal engine
Maintaining control of your valve train’s stability is a key ingredient to creating peak power and durability. The new GoParts™ Animal High Load Stock Class Valve Springs are made from Super Clean™ chrome silicon spring steel wire and are the best springs available today. To be specific, GoParts™ Animal High Load Stock Class Valve Springs deliver 19 lbs. more seat pressure when the valve is closed and 70 more lbs. over the nose of the camshaft lobe; more than any other competitive legal spring.
The GoParts™ Animal High Load Stock Class Valve Springs increase valve train stability so the camshaft in your Briggs & Stratton engine can deliver the most possible power while greatly reducing valve spring harmonics. These revolutionary springs pass all Stock Class WKA rules for wire diameter, size and all other features while handling highly aggressive camshaft profiles and increasing the overall rpm range of your engine.
