Yes. The bolts you crank on to adjust the torsion bars. The Ford keys are indexed differently than the stock ones so they're like starting off where the stock keys would be if you were to crank them up. So, you get your lift but without maxing out the adjusters which means you can crank them down if it's too much lift. It is speculated that some aftermarket lift keys are just stock Ford keys. Maybe since this is a more widely-known thing, the Ford keys are now priced about where the aftermarket keys are/were. But it doesn't hurt to add them to your search criteria when searching for lift keys.
Search for the part number for '97-'03 Ford F150 torsion bar adjusters. You'll need two. A 5 second Google search gave me part number "XL3Z-5B328-CA". It could go by other part numbers.
If it were me, I'd borrow a torsion bar unloader tool and hit up a salvage yard. You're sure to find them dirt cheap there. You can borrow the tool for free from Autozone, they'll only require a deposit to hold on to until you return the tool.
Thanks, what's your opinion on pro comp es9000 vs the bilstein 5100.
