They have a huge problem because they are manufactured. The bolts they use are junk, I've had five days long no spacers on my truck and further the front wheel spacers broke four of the eight lugnats broke four of the eight bolts i took off and pushed out their unwanted bolts that weren't hardened i don't even know what it is and sat real wheel studs, now the spacers work as they should, but for six bucks for the wheel stud, $200 later, I have a set of spacers that work as they should.
