Description
A must for every performance engine to control valve train and maintain proper valve train clearances. Good for engines reving up to 6000 RPM. Dual H-D springs are recommended for engines reving above 6000 RPM. FIT ALL 12-1600cc Beetle style engines. No special hardware is required to install these springs- but our H/D chrome-moly valve spring retainers ( # ACC-C10-5306) are recommended for added strength and reliability.
