I'm running 1/2" lines up front an 1/2" line in rear with 3/8" valves. I've never tried to pick it up quick in the rear while driving tho. My rocker switch box gives me great control. Now on my orange truck with toggle switchs it wud pick up quick but not bad

 

Haven't done the shocks yet, but the speed problem is all in the vavles. Seth told me they are huge orfice on the inside,that's why. Mine hops like 3 inches off the ground at 150psi with 1 quick switch lol. The 1/4' lines are good for speed wise now.

 

What valves are you running? I'm running 1/2" gc extreme 350s on the front an I wish it wud hop well sorta lol

 

Shuda gone with 3/8" line

 

1/2' Gc extreme 250's Valves mounted close to bags. And trust you dont want to hop... Sounds cool but is really annoying.

 

And valves... You live you learn

 

Well thts what I have on the front. Rear is air lift 3/8" with 1/2" line valves probably 1 foot from bags. Fronts are about 2.5' from bags. But even with 150-160 my front won't move like tht. Rear will but I pop the rear to ride height with like 120 an just tap it once an I'm good
