What makes the Hill Engineering tensioner bearing a worldwide favorite? Compared to stock Ferrari (SKF) bearings, Hill Engineering versions contain higher rated grease, stronger bearings, uprated cage materials, and superior build quality (seals, internal clearances, fitting tolerances). Just search the Ferrari internet forums for Hill Tensioner bearings and you will find countless recommendations from many satisfied customers, ex-Ferrari engineers and individuals who know quality when they see and feel it. Hill Engineering bearings strictly adhere to the Bearing Industry code of conduct and have the support of three major bearing manufacturers at their disposal. With nearly 60 years of engineering expertise these pieces are manufactured under strict ISO 9001 quality control procedures.
(Yes -- we still recommend installation of new tensioner bearings with each timing belt service, even though these have a life expectancy of several belt changes. Priced right, we include these tensioner bearings with every timing belt service kit sold at Ricambi America.)
