Accessory Kit

Accessory kit allows you to mount the Porsche alternator and AC compressor to an aluminum Gen 3 and Gen 4 LS block.  

• It uses a LS4 harmonic balancer for wet sump motors and comes with a custom spacer for the harmonic balancer and all hardware. 

• This system will work with the z06 dry sump system by modifying a LS7 crank pulley to add two more ribs to the rear belt position. 

• The kit currently does not work on iron Gen 3 blocks because of a missing hole for the alternator mount.

• Does not include the following parts, I recommend source these from Rock Auto.

  1. Harmonic Balancer (DORMAN 594563)

  2. Pulley (DAYCO 89535)

  3. Belt (GATES K060559HD)

  4. Tensioner (GM GENUINE 12595289) Note that only the GM version comes with the mounting bolt
