Hello, I have a 2016 f-250 that was lifted with 315/70/17 tires on when I bought it. I’m now due for new shocks but don’t know how to figure out what size lift I have. Is there a way for me to figure out exactly what I have without having to take anything apart first? Don’t have a lot of experience with these kinds of things. Hoping I could learn a little here

 

I have 315s and only did a 2” mini spring pack under my front leafs and 2” blocks in back…you have a different front suspension (coils)
Check to see if there are spacers in the coils…also check to see the size of the rear blocks beneath the leaf packs…
If it’s a 350 it should have a 4” block, 250s have a 2” block…anything extra or larger would be aftermarket…315s are just shy of 35” depending on how much tread and type of tire…so it’s probably not a huge lift…
I would check the trac bar and see if it’s adjustable or factory…also the pan hard mount where the trac bar bolts to may be a dropped bracket which would point to more than 2” of lift upfront…very hard to guess without seeing it…but that should get you started and in the neighborhood..

 

There's a few way of doing this. Since you're looking for new shocks, I would recommend this method. This is what true shock dealers/builders will ask for.

1) Measure eye to eye on the shocks while the truck is on level ground. (A)
2) Measure the distance from the bumpstop (your allowable up-travel) (B)
3) Calculate minimum shock distance = L = A-B

When looking for shocks, they should provide you with the extended and compressed lengths. Ensure that the compressed length is less than what you calculated "L" to be at, so that the bumpstop will limit up-travel and not bottom out the shocks. Shocks will most likely be 8-10inch travel. Try to get a shock that sits about halfway at ride height.

A simple method though to calculate your lift height is just measure the center of hub to bottom of fender. There should be quite a few threads on what stock height should be and you can compare that way. It still does not ensure the shocks you buy will be correct. You should be measuring your actual numbers on the truck.

 

Depending on what shocks you currently have there may be a part number on the them by the bottom. Take that number and google it and see what comes up as most mgf'ers also provide the specs that Bajaphile has pointed out. You can likely then cross reference them to most brands.
