Catalog

The kit is for GM cars specifically that have the solenoid on the starter so if you have a GM this is the kit you need. Even so, you can use this heavy duty solenoid on any Mopar or Ford in place of the original as well. It's just a solenoid, but, it does have some "kit" stuff to convert a GM the proper way.
