Hey gang,

1993 RRC EAS - Suspension Bottoms out on large bumps
I have redone my EAS - rebuild the valve block, new rear air springs, and new rear shocks.

When I hit a LARGE low spot or bump on the highway, at speed, I can get the rear suspension to bottom out.

It's a very freaking loud THACK.



This happened before the new shocks as well. Did not drive it before the new Airbags were installed.



WTF do I do here? I my airbag not inflated enough? The EAS settings are on the default heights. It raises and lowers as it should. I can't figure what is wrong. Otherwise it rides nicely!

 

My EAS experience is from my’97 P38, but I think it’s the same system. Firstly, good on you for retaining the EAS and not switching to coils. Unfortunately we have the earliest EAS system with all the glitches, but EAS is much better than coils. I suspect you mean that one corner is fully extending, not bottoming? One of the big advantages of EAS is that it’s very quick to extend and keep the tire on the ground. This is why it is so good off road. Perhaps what you’re experiencing is a negative aspect of this advantage, and not a fault?

 

I mean hitting a bump causes the suspension to suddenly compress to the point it smashes the bump stop, so the axle makes contact with the frame in an unpolite way.
It makes a horrible BANG noise.

 

Oh. Mine does not do that. Is every corner the same? You said new air springs. What about a bad shock?
