I think 1/4" is a bit understated. I will get my micrometer out. . . take some measurements and see what it says.
Just ball parking I see closer to 1/2" possibly more. The front may have more profile than the rear also but I will have to check.
But, yes, if you wish to install spacers or wider tires, the OEM is not what you want.
Misinformation seems it likes to go either way sometimes here. . . . . And 1/4" or 3/8" is understating.
I'll get my micrometer out and take some pics. . It will be awhile though.
