Adjustable Proportional Valve

Part# AL148

This part is used to "equalize" the lift axle in terms of weight to meet provincial regulations. Ontario's SPIF regulations are an example of this.


In most cases, the lift axle and fixed axles do not have the exact same weight vs. pressure curve. This valve allows the installer to adjust the ratio between the lift axle and the fixed axles to balance the weight correctly.

LACM Valve

Part# AL091

This valve is used to control the lift axle. The valve will lift and lower the axle based on the pilot pressure. Once the axle is lowered, the ride bags pressure will match the pilot input.


This valve is not inlcuded in the kits above because most trucks with factory installed lift axles will already have one installed.
