Ratech Install Kits

We Manufacture all of our shims in-house on our own machinery.

We use the absolute finest American made Hardened Shim Stock available.  We not only have the steel checked for metallurgical specifications but we pay to have every square inch of material x-rayed.  That's right.   X-rayed for hidden flaws in the Shim Shock.

We do not use anything less than .010 thick for our shim packs.

We use 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 our shim packs are much broader.   In most cases .020 over and under the normal thickness range --- not just what is the most often used.
