COMP Cams GP971-2 Animal High Load Stock Class Valve Springs

Developed under COMP Cams' GoParts™ performance small-engine program, these springs are purpose-built for competitive karting and snocross applications where maximum valvetrain control within Stock Class rules is required.

Compared to the standard GP970 Stock Class spring, the GP971 High Load design delivers increased installed load and higher open pressure, making it the preferred choice for higher-RPM Animal engine builds where tighter valvetrain control is critical to maintaining power and preventing valve float.

Key Features:

• High load design with elevated installed load and open pressure versus standard GP970 spring
• Engineered for Briggs & Stratton Animal Stock Class competitive racing
• Manufactured from chrome silicon spring steel wire for durability and consistent tension
• Part of the COMP Cams GoParts™ small-engine performance line
• Ideal for higher-RPM Animal engine configurations

The GP971-2 is the go-to upgrade for Animal engine builders looking to maximize valvetrain stability at the top of the RPM range while remaining within Stock Class regulations. Trust COMP Cams' proven spring manufacturing process to deliver consistent, race-ready performance event after event.
