These OEM Toyota bolts have a smaller center section to allow for more camber. Install these bolts in the upper hole of the knuckle and tighten with the bolts with the knuckle pushed inward towards the body. This will result in about 2.2-2.75 degrees of negative camber when you install this bolt into the upper hole of the knuckle and lean the knuckle in.
Bolts and Nuts are Sold individually. You can reuse your existing nuts if they are in good shape.
