2004 disco with a 2” Terra Firma lift and shocks and stock wheel and tires. Brake bumps and washboard roads are just tearing me up! No matter what the speed. Tried going slow, going fast. All is bad. Sounds like the whole truck is going to rattle apart. What suspension setup are you guys running to help with the small high speed bumps? Any tricks? Will a different wheel and tire setup help the ride at all? I know it’s not a race car, but there has to be something. Thanks in advance!!

 

Medium or heavy duty lift? What is your tire pressure?

Lowering pressure will help a bit

 

Unsure of the spring rate. Lift was in the truck when I bought it. I’ve gone down to 20 psi with the tires, not sure if that helped.

 

How long have you had it? How old is the suspension if you recall. Could be time for bushings as rubber does deteriorate.

 

@Jensen Vermont Stenberg I have an 04 with the Terra Firma MD springs but OME (Old Man EMU shocks), washboard is sucky, but its on everything, but otherwise everything else is fine. I run 36 PSI all round on Cooper Discoverer ST/MAXX AT E rated LT tire. When I air down to around 24 off road it is better

 

Do the air springs ride any better than the coils? The reason I’m really curious about this is that most of my off road driving will consist of dirt roads with washboard surfaces. I don’t want to rattle apart the interior of this thing as I intend to have it for a while. I’ve had the truck for about 5 months with 180k miles on it. It spent its entire life on road so it’s in really good shape. Would like to keep it that way. I guess my next step is to try bigger tires so I can air down some more and have a bit more of a sidewall.

 

washboards suck period but if I'm going wheeling or a full day of forest roads I like to drop tires down to 12-15psi and that helps smooth everything out a little bit. I don't think I'd go that low with stock highway tires but a 75 sidewall on a 16" rim and airing down will be your best bet to help some of this. Sustained washboards will generate a ton of heat in the shocks so upgrading to an external bypass shock will help keep the fluid in the shocks cool and maintain performance. That's another route that might be worth exploring.

 

A new steering damper will help on the washboard roads too.
