Whipple 11-26 Mustang Alternator Relocation Kit

Whipple 2011-2026 Mustang Alternator Relocation Kit

The Whipple 2011-2026 Mustang Alternator Relocation Kit is engineered for high-horsepower Coyote builds utilizing an ATI harmonic balancer and a Whipple supercharger system. By relocating the alternator, this kit significantly shortens the supercharger belt path while eliminating alternator bracket flex commonly experienced in high-boost applications. The result is improved belt grip, increased reliability, and more consistent boost under demanding conditions.

Designed to retain the factory A/C system and utilize the OEM spring-loaded belt tensioner and factory alternator pulley, this kit delivers OE-like reliability while greatly improving belt performance for racing and high-performance street applications.

Important Notes

• Supercharger belt is not included.
