I had a chance to call Suspension Connection and they told me to call the manufactor.
They carry DAYstar leveling kits and man I' m telling you the two sets looks almost exactly the same. My only concern is that the spacers are described as (6-lug) for the Tacoma and the 4Runner has no such description. That may be a problem.
Are you just talking about the spacer or the full kit w/ the extended studs? Either way, I believe they fit as my SAW's are interchangeable between a Taco and 4runner.
