I have a '97 F-250 Heavy Duty 4x4. I want to add about 3 inches but I need to keep the same heavy duty load capacity of the truck. I use it for work also. Rancho? Superlift? IDeas? Thanks,

 

Try ProComp or Superlift, ive heard nothing but good things about them. ProComps site is www.explorerprocomp.com or try www.4wheelparts.com. They sell lifts and if you call them up, they will make deals and knock off some shipping costs if you talk to them. I cant remember the address of the Superlift site but they are supposed to be real good lifts for large vehicles. In fact they have a Superduty show truck at Superlift. Hope this helps.
