P30 Springs - Stengel Bros vs. Super Steer

[jcgribks]

I'm needing to replace my front springs on my 96 Itasca Suncruiser w/ P30. I currently have the stock springs w/ air bags and the right bag is leaking. These are the replacement bags from Air Lift that I installed about 6 yrs ago. I think the top little pad popped out and that's why it's leaking.

I've read about the Super Steer springs but then I found a post here that someone used springs from Stengel Bros. How do these compare to the Super Steer springs? If the Stengel Bros springs do the same as Super Steer in that you can do away with the air bags and keep the ride height, then why are the SS ones so much more in price?

Thanks in advance,
John
