What a Rebuild Includes
ModuleMaster uses a 5-step rebuild process which begins with a thorough cleaning
by bead blasting. Next, our trained technicians make component-level repairs using
high-grade silver solder. We then perform a preventative maintenance procedure which
involves replacing all components known to fail with the highest quality upgrades
available. Modules are then thermally treated to ensure longevity. While we do not
have the means to test every module before shipping, we do our best to ensure
trouble-free installation. If you have any problems during installation, please give
us a call. We're here to help.
Unfortunately, there are some Kelsey Hayes modules that we are unable to test before shipping
back to you. However, in the rare event you should have a problem with your rebuilt module,
please give us a call.
All ModuleMaster rebuilds come with a 5-year guarantee against module related
