A: Depends on the height of the rear block Ford had 2.5 inch rear blocks and 2 inch I believe in those years.

A: That’s what I did to my 2006 F250, installed these springs and removed the blocks. Trucks rides so much better. The factory springs are too stiff and made for hauling

A: I was looking for the marking, once I uncovered the silt mud and dirt from the past 2 Baja 1000’s I noticed they said made in ….. for the price I doubt they are made stateside, they ride very smooth and forgiving, better highway ride that the stock springs, as long as you have some good , not rancho or procomp, shocks. You lose some towing capability but only thing I tow is a small keg of Double Barrel Ale. See you on the other side!

A: They did on my f350 nice springs 

A: You want to try and point the yoke of axle towards the transmission. Fat side of wedge goes toward the transmission. The thin side of wedge goes toward bumper.

A: In theory yes, but there are unknown variables: Original spring rate vs new part spring rate. Different spring rate will change height. How many miles are on spring (how much springs have sagged due to use). New spring will sit higher than sagged original spring.

A: Spring Rate is 375 lbs.

A: Yes you would need to measure your block and subtract the difference. That would all depend on what size block is in the vehicle. The lift is calculated utilizing a factory block. Typically 1.5”

A: Hello mule and thank you for the inquiry on the Pro Comp Suspension 4 Inch Rear Leaf Spring. If you are lifting your vehicle 4" over stoc , then you will need to replace your pitman arm to make the steering correct.
