I bought my truck used with a leveling kit on it. My shocks and struts are toast so decided to get Bilstein 5100's and level it so I know whats in there. Took of the struts and coils today and this is what I found....





I was expecting to find something like the AS leveling kit, or some sort of spacer above the strut. Is the leveling kit just a thicker spring isolator? And how will this effect putting on the 5100's? Should I find a stock spring isolator? Part number anyone?

 

The leveling kit is installed above the spring isolator, I think it's a Readylift brand leveling kit. The leveling kit is under the top portion of the strut hidden away

 

that is not a ready lift. ready lift is a powder coated steel part. There are so many leveling kits out there is it hard to tell what they are. But for reference, a 2.5" leveling kit measures 1-5/8" in height and a 3" measures 1-3/4" in height.

Adjustable bilstein's do not require a leveling kit and should not be put together with one.

 

from what is pictured.. theres no leveling kit on it? haha

 

See thats what I was thinking at first too, but look at where the coil ends, in other pictures I've seen the coil keeps going up and you see a lot less of the spring isolator. There has to be a spacer up underneath there. Plus the truck was definitely higher than stock in the front.

But does that look like the original spring isolator? When I do the Bilsteins I won't want a spacer or anything else just the original spring isolator.

 

See that silver piece right above the spring isolator? That's the leveling kit. I can't remember what brand it is, I thought it was ready lift but it may be a different brand.
