Swapping 2 wheel drive and 4 wheel drive suspensions
Hi All! I have a 2007 f150 2 wheel drive. In talking to rancho the struts on a 4x4 and 2 wheel drive have different mounting points so I couldn't use their lift struts. Is this true? If so would changing my springs to a four wheel drives give me the same height as a 4x4 or is it the spring strut combination that gives them the higher stance?
If you're looking at the Rancho QuikLift, I think the 4x4 lifting strut will give you too much lift. They also make stock replacements and the stock heigt 4x4 should be okay. I noticed my upper control is marked 4x4, so there is likely a limit to lift before you start to have alignment issues. If the struts are the 9000 series, they are adjustable so you can tailor your ride as soft or firm as you like.
Well shoot. I was going to try for a cheap man's lift by doing 4x4 struts with a 2.5" leveling kit. However if the a arms are different by the time I'm done getting the parts I might be better off buying and official kit.
Does anyone know for sure if my lift idea will work? Are there different part numbers for the 4x4 a arms where we could compare?
I'm fairly certain there are limits as to how much lift you can get before you start having ball joint and alignment issues. You can't take leveling struts and throw spacers on top of the struts to get 4" or 5" of lift without consequences.
Fabtech makes a 6" lift for late model 4x2s. You might want to look into it for more than 2-3" of lift. Before I took the word of a service manual, I'd check with the part counter at Ford. I looked up the upper and lower control arms on Tasca Ford's website and they make a distinction between 2WD and 4WD. I'm not sure with the 4WD sprindle it won't change your rotor, etc. Unless you have a donor vehicle with all the parts, I would think the Fabtech kit would be the easiest route for that much lift.
