This product was added to our catalog on December 12, 2014.This is an optional TKO Flat & Finished Associated Differential Ring Set. These Flat and Finished Diff Rings use TKO's "Totally Flat Technology" to produce the Finest Diff Rings available. These rings are the same size as the ASC7666 B5 rings, and are direct replacements for the stock B5 and B5M diff rings.
Using TKO's proprietary process the rings are finished to the following specs; The faces are flat to within 2 microns and are parallel to within 1 micron with a #7 finish (one micron is 40 millionths of an inch - .0000040). After processing, the rings are checked with an optical flat and monochromatic light, the ultimate measurement for flatness. Simply wipe the rings with alcohol or motor spray and they are ready for installation.
