Mike's Custom Toys offers the option of:


Sierra Ring & Pinion gears can be ordered “polished” using our in-house (Sierra Gear) Isotropic Superfinishing process.

Simply put, Isotropic Superfinishing significantly reduces the surface imperfections that remain after a Ring and Pinion Gear set is manufactured. The result is a cooler, quieter and longer lasting gear set. The process we use is chemically accelerated vibratory surface finishing. This is technically not a polishing process, however the resulting finish does have a polished appearance. This process eliminates surface imperfections without removing material or changing the physical dimensions of the part.
This finishing process is widely used in racing applications where a conventional break-in process is not feasible, and where optimum performance is not an option.
