Thats would all be great if i knew the weight of my 60. As far as i understand, by figuring out spring rate ill know the static height of the spring when put under the weight of the truck, correct? Now a progressive spring(which an 80 spring is??) is another calculation? Math was never my best subject.
I really just want to know if it will work, what are the pros/cons.

I believe that the air shocks mentioned are an air spring built into a monotube shock. Quite robust, but typically those are not good at carrying much weight or going very fast (temperature largely varies the spring rate). They are quite popular in light weight crawlers as they are simple and effective for that application.
What a friend has talked of doing, but has yet to actually do, is to put a single (large?) air spring at the center of the rear diff. It would carry the weight w/o having a huge effect on articulation. FFT |
