Someone can correct me but I'd say replace with standard shocks and you'll be fine. I replaced my worn out standard with parts store standard brand.

Back in the day fellas would put air shock on their cars to jack up the rear to either clear wide tires or just to look cool.

 

 

I like Monroe/NAPA gas magnums if there still called that. Didn't think much of KYB's.

 

This is what I've got on the rear of my truck. Love them. The ride is very nice as compared to lower quality shocks.

 

I run the "better" gas shocks from AZ. Probably similar to what is posted above. They really helped ride and reasonable cost.

Air shocks or spring assist shocks can help level the ride running heavy or towing but you do not need them in your application.

FWIW my F250 rode like a buckboard with worn and broken OE springs, overload springs and dead shocks. Ditched the overloads, replaced the originals and new shocks as above and different truck. Rides great and still handles 2,500# when it needs to.

 

I was able to score the KYB's for $119 shipped so thats whats arriving. I also ordered some MOOG variable rate springs for up front, and all new bushings for up front, the cab, & rear sway bar from Energy Suspension.

I will eventually get to the leaf springs. I will need to take action on them sooner than later as I noticed on of the leafs has a crack.

 

People use air shocks for a poor load helper, to fix sagging suspension or for "stance". They aren't really built to handle those duties long term though, they are junk.
