How accurate are the shims?
4Crawler Offroad can typically machine the shims to within +/` 0.5 degrees, typically. Shims are checked after machining with a digital angle gauge to ensure they are within this tolerance. Both shims are typically cut from one block of material so the angles are identical between the pair (this is an important design issue). On thickness, 4Crawler Offroad tries to get the two shims within 1/16″ of each other, and within 1 degree variation across the face of the shim.
