Spring rates and valving

[Waitin4dv]

im getting ready to four link my 98 f150 and was wondering if there are multiple combinations for spring Rae's and valving or is there a pretty much a specific setup? Thinking of running a 3.0 coil and 4.0 bypass shock. Pretty much chopping back half off and going all tube and running the gas take near the cab if that makes a difference. Running 37" tires for now. Thanks for any help

What make of shock? Leverage, angle. Total weight of truck when it's "finished", loaded . Fuel capacity, spares, off the back. Etc..

King shocks. I'll have to get the rest of the info.

There are some standard metrics to follow regarding spring preload, but how you get there depends on the things mentioned by Cosmo.
