3/8 1/2 OR 5/16???? SOME ADVICE PLEASE

ok so iv got pretty much everything i need to bag my 87 ext cab mazda now the question i have is what size valves and airline should i run?? i bought my kit off a mate which is all brand new but its all 3/8 line with 3/8 asco valves now everything is still in the box's and i actually got him the kit when he bought it and i have a pretty good relationship with the place i bought it from so if i wanna go 1/2 or bigger they will take back all the 3/8 shit and i can just pay the difference so my question is... is it worth goin to 1/2 or 5/16 i wouldnt mind hoppin a lil bit when i air up... the only other bagged truck iv had was my 02 yota that had 1/2 all round and ran 200psi but still wouldnt hop, it was close to it but just wouldnt get there... so anyway if someone could tell me the pro's and cons to each it would be helpfull.... or is it better to maybe run 1/2 front and 5/16 rear or a combo like that any help would be good thanx in advance guys.....

SORRY I MEANT 5/8... im an australian so we use millimetre's and shit sorry

any help would be good.....

Id swap it for the 1/2" if you want it to hop a bit

I would say stick with 3/8 everything, Easier to hide and tuck away, also 3/8 is still really fast.
There is no need to go faster,

i'm with chinky... 3/8 is totally fast enuf... gc extreme 450 3/8ths ... good enuf if u want the flow...

i have 1/2" fill and 3/8"s dump with all half inch line. i can pull the front wheels about 3 inches off the ground at 200 psi.

cool thanx guys maybe ill get 4x 1/2 valves and some 1/2 airline then and run like dropped90 said thanx again i appreciate it

If you want my opinion, if you DO go for 1/2" fill, make sure you keep an eye on the gauges. That constant "pop" going up gets annoying when you're just trying to air up a little. 3/8 can move... here's a vid I did at 100 psi... the front would still go down too hard so I had to switch out slowdowns.



If you want to dance it, run 1/2", otherwise on our small trucks, 3/8 is enough.
