I currently have a 2" Revtek spacer on the front my 2010 F-150 4X4 with 305/65/18's. My fender measures 39.5" off the ground. Another member has an AS 2" spacer on a 2010 with 305/55/20's (shorter tire) and his measures 40.5"

Does the AS kit really give you that much more lift?

My problem is that I bought 3" blocks from AS to do the rear and the rake is too extreme for my taste. It looks like I can either use airbags for less rear lift or raise the front by switching out the spacers to 2" AS.

Since I already have the blocks, I would prefer to keep them.

Can anyone else provide their fender measurement, tire size and spacer brand so I can really beat this to death.

Thanks,

Jeff

 

First, I recommend measuring from the center of the wheel/hub to fender, that takes out tire size and only accounts for the leveling kit. This is important due to the fact that metric tire sizing varies between manufactures. Therefor when others post sizes you don't have to worry about the delta being added in due to the tire.

Second, from my experience AS does produce more lift than other manufactures. I did a comparison between HellBent and AutoSpring and each spacer from 1.5 to 2.5 varied by a 1/16th. In other words a 2.5 HBS was the same as a 2 AS. That may be the same case for you. Its been ages since I posted in the thread I was talking about, so I am not going to search for it right now (I did not start the thread, so its going to be hard to find). Also isnt the revtek spacer poly?

 

I believe it is poly. The dealer installed it before I picked up the truck. Is poly bad to use?

I will take that measurement when I get home.

Thanks for the advice.

Ok,

So fender to center of hub:

Front 23 3/4"
Rear 23 7/8"

Is anyone able to measure theirs and let me know if I got enough lift out of my Revtek.

Thanks,

Jeff

 

I've got a leveled FX2 with 4x4 shocks and a 2" ProComp spacer.

Front is at 24 3/4

 

Not that they are bad, but unlike the steel spacers, the poly ones are subject to compress, therefor you can loose height. Also since geometry plays into it, the amount the spacer compresses is not proportional to the lift you loose (you loose more lift).

 

Come on, anyone else able to measure their front end?

I think I'm going to remove my Revtek lift and buy a 2" AS lift and use my 3"rear blocks but I would like to make sure I'm going to get another 1" of lift.

Thanks,

Jeff
