RV0421800-00 Spectrum Viscous Fan Clutch
Made in USA!
By creating several universal viscous heads, along with interchangeable brackets and adapters, Kit Masters had narrowed the field of viscous fan drives from over 1000 part numbers, down to just a few components. This unprecedented system makes it possible to have access to a replacements for nearly every viscous fan drive. Replacement may differ slightly from original but functions the same.
