I've got a Revtek Preload spacer installed in my front strut. I now have an AS 2.5" spacer to put in the front of my 05 FX4. Would I have any problem just adding the AS spacer to the existing strut configuration OR should the Revtek Preload Spacer be removed before hand? The Revtek spacer looks to be about 1.25" thick?? Anyone heard of these or used them. Also wondering if there would be any problem removing them and returning the strut to stock?? Please Help...Thanks

 

No, you can't combine the two leveling kits.
