The +5% Alternator Pulley is designed to reduce the speed of the alternator, particularly beneficial when other engine modifications cause it to spin faster. This pulley works effectively alongside an Enlarged Crank Pulley and smaller supercharger pulleys, ensuring that the alternator operates with less strain.

Benefits of the +5% Alternator Pulley include:

• Increased lifespan of the alternator
• Enhanced horsepower due to improved belt efficiency and reduced stress
• Ability to run a higher rev limit for improved performance

Constructed from steel and finished with a galvanic coat, this pulley is also compatible with standard OEM belts when using smaller supercharger pulleys ranging from 11% to 15% sizes.

Custom sized Alternator Pulleys are available for those who:

• Utilize an extremely small supercharger pulley and require further alternator speed reduction
• Have numerous electronic or In Car Entertainment (I.C.E) accessories and need to enhance electrical output for smooth operation

The Alternator Pulley comes with a lifetime warranty and meets all required standards (ISO 9001:2008 and ISO 14001:2004).
