I need to build an air ride rear suspension for my 08 F350.
I'm thinking of building something similar to the Firestone R4 Tech setup.
I like it better than a 4 link because
- much less to fabricate
- no pan hard bar needed, thus there is room to keep a stockish exhaust system, ie rear exit
- leaf springs will locate the rear axle better side to side than a pan hard bar
I have a bunch of concerns
- finding an air bag to fit between the frame and the axle
- air bag having enough weight capacity at a reasonable pressure
- air bag having a decent spring rate at a reasonable ride height
Before I built the 4 link on my old truck, I tried removing leafs from the stock spring pack in the hopes of augmenting with an air bag. It rode terrible. However, I still had multiple leafs in the pack.
If I try this again, I will remove all the leafs except 1.
I have an email into Firestone requesting air bag information on the R4 Tech system.
