Designed for ARC R12 series, this caster angle gauge allows you to accurately measure the caster angle on the R12.
This is critical on the R12.1 where setting camber requires adjustment of both upper linkages. If caster is not correctly maintained at 4 degrees, there will be binding in the suspension movement.
There are 2pcs inside package, one is right side another is left side, the height is adjustable to fit all setup station on the market.
