What size shocks would i need for a 95 F-150 5.8 with a 4" lift?

 

the easy way.
go to a lift website and order them for you truck with a 4" lift

the best and correct way.

take off your shocks, , get something like an engine hoist, or tractor and lift your truck by the front tire, until the back tire on the side your lifting starts to come off the ground. then go to the other front tire(not the one up in the air and measure from shock eye to shock eye.***this is your extended length***

then do the same thing on the side that is up in the airmeasure from eye to eye ***this is your compressed length***

then repeat the same thing on the rear axle.

 

That is backwards if I'm reading you right. With the tire in the air, hanging free is your fully extended length. Tire on the ground with weight is your compressed length. The free hang or droop will be limited bu the length of the shock if it is too short. Unbolt the shock jack up the truck and see if you wheel hangs suspension hangs lower than the stop will reach. You don't want the shock to bottom out in either direction. The spring should stop the droop and the bump stop should stop the compression (at extreme)

 

what ever tire is lifted is the tire that will be compressed in my pic here you can see the pass tire is stuffed into the wheel well, and the drivers side is dropped down. the ground under the pss side of the truck is about 14 inchs higher than the ground the driverside is on.

 

you dont lift the truck by the frame you lift it by the tire its self. just like the tire would be it you ran one tire up a ramp, or rock.

pass side extended drivers side compressed

 

here is one with a cherry picker/engine hoist

 

thanks for the pionters guys ill try that and see what i come up with and see how that compares to what the "lift site" says i need.

 

Ok I get you now. I was thinking of lifting by the frame. Right you are sir, carry on. But if you only have a jack the other way works.

 

By the way, you've got some big brass cahones to be crawling under that rig to do some measuring.
