The Valve block & Air Spring Faults

There are two major Faults:

1) The reason your car sinks to the bump stops every night is due a leak somewhere in the EAS system. As a particular bag (the most common issue) slowly leaks out, the EAS system tries to add air from its reservoir to keep it inflated. The air leak eventually drains the reservoir and then the system is forced to deflate the remaining bags to keep the vehicle level. Over the course of a night this can completely deflate the entire system. Once the system is restarted in the morning, the compressor must first fill up each bag to normal height, and then it must refill its empty reservoir tank back to capacity.

2) The delay in the truck raising in the morning is due to a worn out compressor, which is typically due to problem number 1: leaks. Since the compressor has to refill the tank every morning, plus each spring, it is being used beyond its intended duty cycle, adding premature wear to the unit.

The valve block o’rings get hard at the reservoir hose inlet also leaking all the air out.

The recommended solution to both problems is to first, update and restore the EAS system, and to rebuild the compressor. We have fully over-hauled Valve Blocks that we can exchange or do your unit to tackle both problems.

We recondition these units to near new condition.

We also carry the 'air bellows' by themselves, to help keep the cost of repair to a minimum.
