Crane Distributor Vacuum Advance Stop Plate 99619-1

Description

Here’s an easy-to-install item that allows you to limit the amount of vacuum timing needed for certain engine/vehicle applications using the Crane Adjustable Vacuum Kit. With Crane’s Adjustable Vacuum Advance Kits, the adjustment made through the vacuum port of the cannister adjusts the rate of vacuum timing change as engine vacuum changes. This is especially helpful with applications such as high compression ratio engines, heavy engine loads (such as very low numerical rear axle gearing) or heavy vehicle weights such as motor homes, trucks with trailers, etc.
