I just purchased some 20"kmc rims with 305/50/20 cooper zeon ltz tires..Now I just found a local guy selling a 3.5" donohoe racing shackle kit for 500 and im wondering if that 3.5" is enough to clear the rims/tires?? I have a 02 f250 4x4..any input would be greatly appreciated!!!

 

Get the tires n wheels you have bought then put one on the truck to see how that looks on the stock shackle height and clearance to the wheel wells/fender for starting with just the basic eye ball comparing. Then you will have a visual guesstimate of what it can be for a general idea after the new shackles are put in.

 

the 305/50/20's are 32" tall. If your truck came with 265/75/16's they are 31.6" tall or 265/70/16, which are 30.6". I'd say that no lift is needed to run this combo.
