Description

EC Billet Steel King Pin Bearing Housing – For Custom Racing Spindles


The EC Billet Steel King Pin Bearing Housing is a precision-machined component designed for building custom front spindles on racing go-karts, lawnmowers, and other small-engine performance vehicles. Manufactured from high-strength billet steel, this housing provides the durability and alignment needed for race-duty steering systems.


It is most commonly used with EC’s 2504 or 2507 spindle shafts and 732 spindle control arms to create a fully functional spindle setup. The housing is compatible with 731-style 1/2" kingpin bearings (sold separately) and allows for smooth pivoting action and long-lasting performance.
