trouble with front bags

I have a 94 caprice that i just bagged.It doesn't seem like it has enough pressure to lift the front(gets about 40-50psi at each hit of the switch)I'm running "2" 5 gallon tanks(connected together),"2" Viair 450's,& 1/2" valves(pressure switch kicks off @ 150 psi). Anyone have any ideas....thanks in advance

what size bags up front ?

do you have firestones or slams??? What size bags???

Sorry, I have Firestone 2600's

I would up the pressure switch to 175psi. Make sure you lift the front of the vehicle first, then the rear. Firestone 2600's are fine for the front of a caprice.

leave the psi at 150, you will save the life of your compressors, 150 psi is PLENTY to lift a caprice. any fullsize ive done will get plenty of lift in the front @ 150psi.

Yeah i had 2600# firestones in the front of mine for a while and I had a shit load of lift!! Like everyone else is sayiong just make sure you lift the front first.Do you have a gauge on your tank to see how much pressure you have in there???

get a engine driven run 260 psi call it done

do you have any kinks in your line to the front bags , my car runs at 150 and it doesnt matter w/ you lift first the front still lifts to the moon unless the pressure is down
