Product Overview
A Gilmer drive uses toothed pulleys rather than a conventional V-belt arrangement. The correct pulley spacing and water-pump length are crucial, especially where short- and long-water-pump combinations differ.
Builders typically install these kits during a performance or appearance project, not as an ordinary service-belt replacement.
