Frequently Asked Questions

The Holley 20-166 alternator bracket kit is engineered specifically for GM Gen III and Gen IV LS/LSA engines using standard LSA crank dampers or aftermarket equivalents. It is also compatible with 2010-2015 Camaro LS and LSA water pumps.

No, the kit includes the natural finish cast aluminum mounting bracket, high-strength assembly hardware, and an alternator wiring plug (P/N 197-400). The alternator and drive belt are sold separately to suit your specific belt length and charging requirements.
