Upper Control Arm to Coil Spring contact:
AutoSpring has found that a very select few F-150's still have the upper contral arm to coil spring contact at full upward deflection even with our offset kit installed. This is because Ford uses multiple vendors to supply their strut assemblies (outsourcing). Unfortunately not all the vendors that manufacture the strut assemblies machine the internal strut shaft exactly the same. They found after inspecting numerous worn out factory struts that the shaft length can vary up to 3/4". The longer strut shaft allows the front suspension to droop farther than normal.
They were advised by a local Ford dealerships that they have had the upper control arm to coil spring touch problem on some stock F-150's with NO leveling kit installed. They replaced the strut assemblies on these trucks and the issue was resolved. They found that replacing the strut assemblies with Rancho or Billstein brand strut assemblies also stopped the upper control arm to coil spring touch issue. The upper control arm to coil spring touch only occurs when the tires come completely off the ground. This rarely occurs under normal driving conditions. Autospring found that the upper control arm to coil spring strike only takes the paint off the coil and does no permanent damage to the coil or upper control arm. They recommend that the owner replace the strut assemblies with new Rancho or Billstein strut assemblies after the truck has @75,000 miles on it. That is typically the life cycle of a factory strut cartridge.

As per auto spring... The earlier versions you'd have rubbing issues..
