So just yesterday I got air shocks part#ma785 for the front of my80 I cranked the torsion bar all the way down but wen I fill the shocks with air they only go up an inch and a half. Does any one knowwhy? The shocks are Monroe air adjustable shocks can some one please help me I was kinda numbed because it says 4.5 inch travel and it's no where near it

 

maybe your air compressor isn't giving enough pressure

 

I agree with Clark. Probably need to adjust the PSI on your Compressor to match the amount of PSI required to air up the Shocks.

 

Li used two compressors so I don't thing it's that they both pumped to 150 but don't give the shocks full extension

 

Have u tried lifting the truck on jack stands and then fill the shock and watch the travel ?
Or is there any tension on the torsion bars at all

 

Actually I seethe torsions as low as I could go before the fenders touch the tire so that way wen I park I can slam it and wen I drive I can lift it all the way up but it only goes like half way ... Could t be that there is to much weight?

 

I dunno I've never had air shocks . Don't think they are designed to lift like a air cylinder or bag so I would try lifting the weight off the truck jack stands filling them up with some good air pressure all the way . Set it down and if it's higher than before than yea they can't lift the front on there own

 

Ohk thanks bro that got me thinking they are made to level heavy loads so sence it's in the front and not the back that could have pilot alot of weight

 

air shocks

All the air shocks are supposed to do is level the truck out with weight in it
