I've mentioned before that the ability to adjust the perch setting on the OE front shocks was an "Easter Egg" given to us by SVT and Fox, but I didn't recommend having this modification performed at a Ford dealership. If you have the perch height modification performed at a Ford dealership, they're going to have a record of it in your service history and it will make it easier for Ford Motor Company to deny a warranty claim, specifically for any front suspension/driveline related part.
Ford Motor Company has caught wind of the mod and released the following TSB (Technical Service Bulletin):
TSB SSM 44422 - EFFECTIVE 2/14/2014:
2010-2014 F-150 Raptor only - the front and rear shock absorber assemblies are non-adjustable. Attempting to make adjustments to the front and rear shock absorber assemblies will alter the ride height and suspension control outside of factory design specifications. Refer to Warranty and policy manual for alter vehicle policies.
I do recommend setting your truck on mid-perch for improved off road handling characteristics because I feel that the positives of the mod far outweigh the negatives, but people who are going to do it should be aware that the increase in suspension angles as a result of the mod will slightly increase the wear on your CV joints, ball joints, tie rods, and UCA/LCA frame pivot bushings. Now, more than ever because of the new TSB, there's a chance it could give you warranty grief in the future.
Many of us know that most Ford service departments don't even know that the front OE Raptor shocks have an adjustable perch setting. Use that to your advantage and have the modification done somewhere else other than the dealer. If they don't know the mod exists, they're probably not going to notice that the truck isn't on the stock setting when you take it to the dealer for service/warranty.
