Ok I need help I installed my d2 air ride basic kit in my gs4 and the issue I'm having is I had the car at normal height and when I air it out from the the manual paddle valves it went low but then when I went to air it up it doesn't wanna go up. any comments would help

Your tank might not be big enough. Is the tank of air?

LazyLagger

Or one of your airlines got kinked. Check ur lines make sure theres no bends or kinks

Leak in hose? It's bound to be leaking somewhere IF you tank and compressor works.

Sorry for late response ok so compressor turn on fills up tank I slam car to floor the rear raises but the front doesn't wanna go back up unless I jack up the front then it'll stay up but at like 140 psi up front 100 psi in the rear..guy who helping install said maybe d2 sent me bags for a gs300 instead of 400 u think that would matter?btw all the fittings were changed to push connect ....I'm gonna call d2 and see what's going on tomorrow

I'm not sure if the tank big enough bought the whole kit all together brand new from d2

GS300/400/430 is the same suspension setup. U might need to run more pressure to lift the front up. What kind of pressure switch u have? 150/175/200?

140/100 psi is crazy pressure! I drive at 80/60psi. Do the struts have adjustable collars at the bottom of the bags?

baggedgs4

the pressure switch it came with in the kit is 120-150 the tank is a 5 gallon

baggedgs4

yes the bottom of the strut is threaded like a coilover

John9689

Have you tried adjusting them up?

This is your problem! Tank is fine. Throw that switch away and get a 175-200

baggedgs4

Geez your 100% correct I took the switch out replaced for a higher pressure switch and now car is fine
