If you tell us what you're looking to get out of the level we might be able to give some better advice. From all accounts in this thread, having a spacer on top maintains the stock spring rate. In other words, the ride is basically the same as stock. Having a spacer below the upper strut mount increase spring rate and decreases upward motion of the wheel making the ride stiffer. I installed the 5100s because the stock ride was too soft up front for me. From the picture you posted of the split spacer, you'll gain the level you're looking for and the ride will be a little stiffer than stock.

Actually, I want to know what and how the suspension and associated parts are changed/affected by doing a level to a F150. Knowledge is power, right?

So a spacer above doesn't affect anything other than lift the truck, and a spacer below will affect the ride stiffness and reduce shock travel. I assume you can raise the front of the truck quite a bit if you wanted with a spacer above. But a spacer below is very limited in height lift. Doesn't seem to make sense why there would be a spacer ring used below if there are negatives and no positives.

I understand using the "full monty" is better (the 5100)...but like anything, if you have unlimited cash you can get the best of everything.

As far as I can tell, all of the 2 inch lifts affect the lower control arm and the ball joint the exact same. The limit is in the control arms, which is about 2 1/2 inches. More than that and you get problems. Lift kits (not level kits) and replacement control arms eliminate or greatly reduce these negatives. A stiffer ride (to a point) is not a negative in my opinion. If you like how the truck rides as it is, go with the spacer on top. If you want to tighten up the ride a little, the split look like a good option.

Thanks, that's been the most helpful info, I imagine lots of people would like to know that (not just me).

I like the limo ride, to a point, but I don't care for the body roll that is apparent even when I change lanes. Would the split (above and below) help a bit with that since it stiffens up the suspension?

I don't know anyone who has used the split spacer but it sounds like it will meet your needs. If you get it, make sure you put a short review of performance on this thread for future reference.

The used kit is still for sale ($50) I'm somewhat surprised no one has purchased it. It sells new for $160-ish. The "usual" "above the mount" steel levels are only $85 and no spring compressor hassles. Not decided what to do. That's why looking for a lot of detailed info.

hi
Im looking to raise my truck a small amount since i almost ripped the front skirt off on a curb while parking!
Really? its a freakin 4x4
Was thinking simple 2" level
my concern is with a load i will have sag
what would you suggest be my best option?
wtf are the levelling shocks?
what about an adjustable air ride?
thanks

First off, I want to say thanks to everyone that has posted on this thread. I read all thirty pages when trying to make a decision on what leveling kit to go with and after saving up for awhile (want to do it right and get the highest quality solution I can afford) I got the Bilstein 5100s. They were installed by the local offroad shop here in Pearland on Friday and so far I am very happy with the improved stance and handling.

I'm not regretting my decision at all, but I am hoping that someone could help a beginner out in understanding exactly how the Bilstein's work. I know I should be able to figure it out from the previous posts and Bilstein's website, but please forgive me if I am still a bit confused. So just to clarify, the 5100s work by increasing the preload on the factory coil? By itself, this would lead to a bumpy and potentially dangerous ride (a potential downside of a spring preload kit) but the 5100s address this problem by adjusting the rebound valving to compensate for the spring preload. So they level the front while maintaining a comparably safe and comfortable ride and maintaining current up travel and down travel. Is this correct?

Thanks for helping a beginner understand his truck's systems a little better.

I put the medium duty rear airbags on after the leveling kit. $350 bucks installed and when towing I can easily keep the truck level. When not towing easy to adjust and keeps the ride smooth as factory. I am surprised that no one ever brings this up. I had put them on my 09 with no problems 80,000 miles and after 4 years and now put them on my 13 model.
