I recently had my coilovers rebuilt by @DialedShockPrep a couple months ago and I am putting the truck on its own weight for the first time with it being a completed running driving vehicle. They’re 10” coilovers and I have 500 over 600 lb springs. The truck isn’t caged - it’s a dual purpose truck I’d like to drive to the desert, explore, and get back home with. After reading his 50% up/down travel for non-race trucks, I know I need to shoot for 5” of up and down travel on the shock shaft.
What I’m not sure about is preload on main vs. tender spring and reaching that ride height. I know he says something like 1-1.5” of preload on a spring is “good” (I remember screen shotting something like that but I can’t find it on my phone to fact check myself). But how do I pick the ratio of preload between coils to achieve the proper ride height? FWIW it’s a 4x4 A arm truck and it’s got 6” of up travel out of 16”total in the rear so I am addressing that with an HD leaf pack I have waiting around for it.
I’m ok with a smidge less than 50% up travel as I don’t mind a bit lower rode height overall but if that’s a bad idea, I don’t mind going with the 50% up.
