    Added a load share kit to new front springs with all new bushings hangers and kingpins and shocks. Can't find a psi for the bags to make them actually ride good. What psi are y'all running on front axle. So far this looks like it's been a complete waste of money. Front rides crappy with or without airbags being used. Thanks I'm advance

    Though it's apples to oranges, my 1995 379 came with an aftermarket Donvel airbag system on the front between the frame rails and top of leaf springs. Bags were leaky so I replaced them.

    It has an inflate/deflate with a gauge that I air up to 30psi.

    Honestly, I can't tell much difference between aired up and no air.

    Best difference I ever felt in front end were the Road King shocks that I never had any of the issues that others did with - they're now out of business, but I think FOX makes a similar heavy duty shock?

    Yea I've tried 30 psi and it helps with sway on smooth roads but on bumps it slams kinda hard and backlashes very quick but thanks for the come back

    Try a premium shock. If those RK ever give out I’m trying the other ones - )fox?( -

    I hate a rough ride.
