Our premium and most universal Multi-Stage mounting option. We call it our “Double Double” and it consists of a heavy duty aluminum anodized bracket, stainless mounting hardware, and two of our SMX 501 filter heads.

This system is unique because it can be assembled for right or left inputs/outputs and (optional) double vacuum gauges enabling it to measure each filter individually. Additionally, the use of the SMX 501 filter heads allows this system to operate on engines that have flow rates up to 120 gph with a minimum pressure drop. Currently, we are supplying this unit with drag pointer vacuum gauges, supplied through Designated Engineer. The Double Double option can be configured for use on any of our dual head Multi-Stage kits.
