Documentation
Description
HOI retaining rings are axially assembled internal circlips with inverted lugs and are part of Rotor Clip’s tapered section retaining ring family. Functionally similar to standard HO rings, the lugs on HOI rings are reversed. This inverted lug configuration reduces how far the lugs extend into the inner circumference of the housing/bore, allowing other assemblies to pass through unimpeded.
