ScubaSteve Posted November 24, 2018 Share Posted November 24, 2018 Does anyone know what the original ride height is on a 1986 f150 2wd? I am trying to see just how much my springs have sagged. Link to comment Share on other sites More sharing options...
Gary Lewis Posted November 24, 2018 Share Posted November 24, 2018 I may have it in some of my dealer lit, but it will probably be Sunday before I can check. Link to comment Share on other sites More sharing options...
Steve83 Posted November 24, 2018 Share Posted November 24, 2018 There are too many variables - options, springs, tires... It's more-important to check for LEAN than for height, because there's no way all 4 springs can sag exactly the same amount. So if the lean is in-spec, there's not enough sag to worry about. https://supermotors.net/getfile/576476/thumbnail/leancheck.jpg https://supermotors.net/getfile/576903/thumbnail/alignmentfrontwheels.jpg This chart contains 1 ride height spec (for Broncos), but I'm not sure where or how it's measured: https://supermotors.net/getfile/968733/thumbnail/drivelineangles9296b.jpg Be sure to check for bent/worn/damaged suspension components - especially sway bars & all bushings. It also helps to wash & grease between the leaves every few years for a MUCH-smoother ride. Link to comment Share on other sites More sharing options...
ScubaSteve Posted November 25, 2018 Author Share Posted November 25, 2018 I may have it in some of my dealer lit, but it will probably be Sunday before I can check. I have found specifications in the past on other trucks that gives the measurement from the top of the axle to the frame and was wondering if there was something similar on the f150's. Not worried about the actual truck height. The truck does not lean from left to right but it sits level front to back and I know that's not right. I am just curious how much actual spring sag I have in the back. Thanks, Link to comment Share on other sites More sharing options...

And having studied them a bit I find that in that manual there is no set "ride height". Instead there is a range of ride heights and associated camber and caster angles for each of those angles. Tomorrow I'll look in other books to see if there is a recommended ride height. And, I'll try to figure out how to put the pages with the info on the website.
