Thread: Airbag man rear suspension fitted

Where are the valves Simmo - I couldn't spot them in those photos.
Have you got them somewhere near the bags?

The solenoid valves are a standard disco 2 SLABS unit, ie a compressor solenoid valve for each of the two rear bags, plus a down solenoid. its mounted under the LHS rear passenger set. I used the electric plane to make the bottom flush is the only modification to it. It's 100 % original, so I can easily get parts, the unit cost $100 from MR automotive.

The gauge, (twin needle 0-50 psi)and rocker switchs came from gumtree or ebay from a company in victoria i think, maybe another $100. there is 2 x 4 mm lines, ( land rovers std size), that connect them to the suspension on each side that com up through the floor.

The wiring is mostly for the suspension, but 2 of the 4 relays are spares, "for future use", there is also a voltmeter/ twin phone charger as well. Another twin phone charger is in progress for the back seat.

Of the 2 working relays one is for the suspension, one is for the compressor control, (40 amp). The other is the "master",(30 A), when the ignition key is turned on the panel is powered up for "control power", switches, gauge light and relays control power.

The "small consumers", the voltmeter and phone charger are unswitched, and remain on even when the car is turned off.
The power for the panel is fed from the battery to the panel via circuit breaker, with fuses on the various circuits. you can see the fuse panel in the center of the picture.

It takes 21 psi to lift the car off the bump stops. ( I put the car on the bump stops to park it under the house occasionally)

The axle is clear of the bump stops by 100 mm at 31-32 psi, and the back lip of the roof is 2000 mm above the floor. Thats my normal driving condition for light load and around town.
I don't see any real need to drive around on the road with he back sticking up in the air.That means too much air pressure and not a nice ride IMV.

The ride on the back axle reminds me of an old range rover, I hardly even feel the road bumps on the back, but still notice them on the front, the OME springs and shockers were a vast improvement on the LR suspension it came with second hand. ( it was the HD version i think).

My car has an OME 40 mm lift at the front, with 32 psi in the rear bags the car is slightly high at the back maybe one inch.

I'm still using my old OME nitrochargers, they are still working well, but have an easy life now. If I go on a long offroad trip i think I'll have to replace them.

Thanks for the detailed explanation....do you have manual inflation valves as well?
