This is a pack of two optional TKO Flat and Finished D Type On-Road Differential Rings, for use with most pan cars... 12th and 10th scale. TKOs Flat and Finished D style Diff Rings use Totally Flat Technology to produce the Finest Diff Rings available.

Using their proprietary process, TKO ring 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.

Wipe rings with alcohol or motor spray and install.
