This kit includes three full spindle units engineered to match the fit and mounting pattern of common Ariens and Gravely models with 34\" through 48\" decks. Each replacement measures 4 1\/4\" (107 mm) in height and is built for a direct swap where the original spindles used the same part numbers listed.\u003c\/p\u003e\n\n\u003ch3\u003eWill these spindles fit my Ariens or Gravely model?\u003c\/h3\u003e\n\u003cp\u003eYes—these assemblies are designed to match the bolt pattern and height of the listed Ariens and Gravely spindle part numbers.
