Wow. Lots of great info and feedback. Thank you everyone. Tires are at 37 lb.

Can someone suggest some coilovers I should get instead?

I'm going to be returning these to 4 Wheel Parts and demand they make this right since this is what they recommended with my explicit request of a super soft ride.

Well there aren't a lot of options for 6" lifts without spacers. BDS makes the fox 2.5"s that I am putting on for 6" lifts. The dirt logic from the fabtech. But those are gonna run you an additional $1500-$2000. Or you are looking at a custom build which will cost you but that can be set up however you want it.

If it was me, I would get the spacers for 6" lift and my stock coilovers back and just run that for now.
You could also do the bilstein 6112's which are about $550 set at stock height and use the 6" spacers.

Or you could get the spacers for a 4" lift and then run one of these options. These options will provide the other 2ish inches of lift to equal 6"s.

Boss/Halo Lift coilovers are considered one of the best street rides but that will net you an additional .5-1" of lift in the front. The fox 2.0's are also good with the same .5-1" lift, but they aren't quite as good as the boss and are the same price ($800ish)

There isn't anything wrong with spacers made for lifts. Leveling spacers cause angle issues, lift kit spacers do not. There also isn't anything wrong with running them for street queens. The only issue comes with HARD off roading as it just creates another stress/break point where the coilover meets the spacer.

I've always thought of spacers as pr-compressing the spring to raise the truck, and thereby making the ride more stiff / harsh.
You are saying that as long as the spacer isn't compressing the spring, (because the lift kit is providing the full 6" of lifting), then the ride will be identical to factory..???
Is this correct?

jdunk54nl

Yes, that is correct.

A spacer that comes with a lift works "differently" than a spacer that is just used to level. This is because the lift has other parts that correct for the spacer where as the level does not.

Thanks again for everyone's help! One more question. Does 12 inch vs 10 inch wheels increase ride stiffness on pavement?

jdunk54nl

No, wheels won't make much of a difference other than their size 18 vs 20 vs 22. This only makes a difference due to the sidewall amount on the tire. A 35" tire on a 20" wheel has less sidewall compared to an 35" tire on a 18" wheel. Beyond that the tire you use makes a difference and the air pressure you keep it at.
Most off road E range tires CAN have them inflated to 80 psi. Mine are like this but I run them at 38 psi rear and 41 psi front because that is where they wear even. Most f150's are around the same unless you are pulling a trailer. When I do that I bump the rear up to 45 psi. I did the chalk test (google it) to figure out my pressures. You could also look at a tire pressure table.

What you've heard is correct. Coilovers should provide a better ride on both street and off-road than the stock + lift spacer. I have a BDS 6". I started with the 6" strut spacer and stock strut, and then upgraded to the BDS / Fox 2.5" coilovers. The ride on both street and off-road is significantly better with the coilovers. I can't imagine you will get an improved ride by going "backwards" to a strut spacer.

I only scanned the comments above, so apologies if I'm repeating, but what size wheel are you running? Did I see you're running 20" wheels with 35" tires at 37 psi? Maybe try 35 psi? If you're on 20" wheels with not a huge amount of sidewall, that will make a difference too, as someone commented. I'm running 37" tires on 18" wheels so I have a lot of sidewall. My ride is very comfortable. Way better than stock.

I would've gone with an 18" wheel. Softer ride and more sidewall for off roading. and people won't think you're a poser.

Off topic question.. you can get 37's on a 6" lift without rubbing horribly? I have the raptor bumper..

Also do you live best Orlando? Would love to check that out...

You can get 37's on a 6" lift, but it will require some trimming and / or mods to the truck depending on what wheel / tire combination you go with. My wheels are 18 x 9 with a +1 offset / 5" backspace. I had a specialty off-road shop do my truck and trimming and I have zero rub lock-to-lock. I live in Tampa Bay, but he's a few photos of my truck so you can get an idea what it looks like.
