Ratech wants all racers to know about The Myth that “All Shim Packs in the market are the same. They’re just washer shaped steel that come in different thickness.” WRONG! Ratech manufacture all of their shims in-house on their own machinery. Ratech uses the absolute finest American made Hardened Shim Stock available. Ratech uses only hardened shim stock not sheet metal gauges. Shim stock comes in .002 increments whereas sheet metal is soft and the gauges are all over the map with many gaps in thickness and .0005 sizes. The thickness range of Ratech shim packs are much broader. What does this all mean to you? No more pinion shims splitting when used in performance applications. No more gaps in the shim pack thickness range. No more problems getting a non-OEM gear set to the right specifications because it was made to wider tolerances than OEM. Ratech designs, manufactures and resells small parts for automotive and light truck axles. Ratech is not a large conglomerate selling all types of products and Ratech is not a packaging house. Ratech knows what they sell and use what they sell on their own cars. Ratech Ring and Pinion Installation Kits come in several series.
