[stroker87]

Need to replace the 2 rear bags on my 95 GMC sierra

right now it has 1/2 ports and two bolts on top one on the bottom

there is so many options whats good to use? i'm not towing just cruising around the system is capped off at around 190psi

I have no idea 2 ply? 4ply? rated lbs? usable height?

I want some thing thats going to last for a while and give a decent ride
