Thrust pads are one of the only products that are static poured at the shop. Once finished, thrust pads are lapped eliminating any high spots that would create excessive heat. If you send a complete thrust assembly, we will check the rockers and housing for wear - and if needed will regrind and resurface the entire assembly to like new conditions. Incoming and outgoing stack checks are performed to make sure your "as found" height doesn't change. It can also be adjusted to your required heights. We can also provide you an oversized shim so that you can be ready to grind if needed.
