Spring rates and valving


Well-Known Member
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..

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