EAS Valve Block Diaphragm Repair Kit for the electronic air suspension valve block.

The valve block is the control centre of the air suspension circuit: it distributes compressor output to the individual air springs and vents them to atmosphere on demand. Each solenoid seals against a rubber diaphragm, and once that diaphragm hardens or splits the block leaks internally, which shows up as slow ride-height loss and repeated compressor cycling. This kit renews the sealing interface without replacing the complete valve block.

The kit contains the diaphragm, its O-ring, the washer and the retaining screws.

Frequently asked questions

What is the EAS valve block diaphragm repair kit for?
The EAS valve block diaphragm repair kit renews the internal diaphragms inside the electronic air suspension valve block. Worn diaphragms are a common cause of air leaks on Range Rover air suspension.
Which models does this repair kit fit?
This diaphragm kit fits the Range Rover Classic 1992 to 1994 (from VIN JA610294) and Range Rover P38 1994 to 2001, both with EAS air suspension. Confirm your vehicle has air suspension before ordering.
What are the signs the valve block diaphragms have failed?
Worn valve block diaphragms leak air, so the suspension sags overnight or throws EAS faults. This kit reseals the valve block on the Range Rover Classic and P38 instead of replacing the whole unit.
Is fitting this a DIY job?
Fitting the diaphragm kit is a specialist repair. The valve block must be removed and the air system depressurised, so it is typically done by someone familiar with Range Rover EAS rather than a first-time DIY job.
