Ride Height Calibration after Lift

[JohnGalt]

A while back I installed Hypercoil 1”/2” springs, Foutz top hats and 38s. The ride was noticeably stiffer, but I marked it down to new springs, sturdier sidewalls etc. I got used to it. Then I drive a friends stock Raptor and I realized the difference. It couldn’t be right.

My truck reacted harshly to small bumps and potholes in otherwise smooth rides. Seemed okay off-road, but very noticeable on road.

About that time I saw a post somewhere on whether ride height needed to be recalibrated after a lift or not. Learned separately how to check the ride height and recalibrate the VDM module in Forscan.

Sadly I forgot to check the ride height measurements before recalibrating, but the recalibration went smooth. My truck is riding much more like stock again.

In any event, if you’ve done a lift and not done the recalibration you might want to look into it. If you’re Forscan capable it’s a very quick service procedure.

I'm not sure about the calibration, but I have an almost identical setup, except I have Hypercoil springs and 38 x 13.5 R17 tires. I felt the same way when I finished the install. I adjusted the air pressure, and it had a massive impact on ride quality.

I think I remember your install, you had E rated tires, correct? I’ve got Ds, but running 38x13.5x 17 at 36 psi on road.

You still might want to check your ride height and run the calibration, if you or your shop didn’t. A super simple procedure (if you’ve got Forscan) and it rides noticeably better than it did.

I’ve come to learn having your ride height out of tolerance has adverse aspects beyond stiff on road handling.

I also advise running the ride height calibration if different springs or shock collars are installed. The calibration should reset to the "new" ride height as the baseline for the Fox active shocks which effects everything shock related. If the lift was installed at a Ford dealer, the technician should have known to run this calibration post install.

My local Ford dealer service department has Ford Mobile service, and this seems like a reprogramming candidate for that service.

Interesting. I was unaware of this. I have seen a few mentions of Forscan. I'm blissfully ignorant, but it appears to be worthwhile. Seems I need to dive into this a bit more.
