the idea of cutting the frame on a new truck is not something im gonna do. i want to put on the bilstein 5100 shocks and struts and get a little bit of lift / level but if its going to make problems i may just skip the headache. any one have a "safe range" suggestion? the ride height is adjustable, i do not NEED lift for bigger tires etc. i mainly want the upgraded shocks and struts. i would like to have the front closer to level but still have the truck raked a bit.
Everything I read said you need the diff drop at 3+ inches of lift. I set my 5100's at 1.8" the second highest setting. Ford installs the 2.0" lift an honors the warranty so that tells me 2" or less doesn't affect long term durability. A lot run 2.5" an 3" of lift without dropping the diff an I haven't heard anyone on here complaining of a failure but I'm fine with the 2" or just under of lift.

How much do you use your truck off road? Funny thing; being lifted in the 3.5" to 3.75" range, I had no problems off road. But three times, while turning left out of driveways on asphalt surfaces, I heard a little binding up front on the right side. That's what drove my desire to drop the diff., just in case. I've been out a bunch without any issues though.

I also retained the parts cut off, and they can be easily welded back in just a couple of minutes. :D

I think you will probably be fine with your desired level of lift with the 5100 shocks and struts.
I am off road a lot typically one day a week or more. I think i would be more than happy with 2 inches or less lift in the front. most of my reason for wanting the shocks and struts is to get rid of the extra bounces in the front and wiggles in the rear. :rolleyes: thank you

I hear ya. Before I did my suspension, the rear end did not like bumps at speed!

I told the dealer I wanted max lift with no diff drop or change to warranty. They did 3.5" BDS lift and said no diff drop required.

I'm at ~15,000 miles with ~1000 miles on moderate off road trails. No noises, signs of wear or other problems. I'll do a good inspection in the spring when I change wheels, but not expecting anything to be off.

Doesn't the 3.5" BDS lift come with the parts to do the diff drop?

There are multiple kits. Basic lift only, UCA kit, coilover kit, etc.

I did this because it's all temp until the rest of the tuck is built. I wanted tires immediately so did a basic lift. Once everything is added full suspension replacement is my last step.

No photos, but had my first outing with the diff drop today, tackled a couple good obstacles in 4-high (locked in the rear, not that it matters to the front) and I had no issues with the diff drop. Everything worked beautifully and I scared the hell out of my friends on an off-camber obstacle! (They thought I was going to roll, and then they saw the whole underside of my Ranger when I went crazy on the wheel lift!)
