If you put a 37 and 35 shock side by side you can see that the spring perch on the 37 shock is preloading the spring a little more. Then in the rear the part that connects the spring to the axle is different between the two. Doesn’t account for a whole lot of height on its own, but it’s not 100% tires that make it different. Ford could have kept the same amount of preload on both trucks and reduced unique SKUs at the expense of the 37 truck having a weird ratio of up to down travel, but they didn’t do that. I think it’s commendable that they did something to not have that ratio messed up for 37 trucks because realistically not many would have noticed.</p></blockquote><p></p>
