High-strength replacement spindle assembly engineered to restore cutting performance on 46-inch lawn mower decks compatible with Cub Cadet, MTD, Troy-Bilt and several Craftsman models.

This spindle assembly (JSXDNWYJ model replacing OEM 918-04865A / 618-04865A series) is a direct-fit replacement designed for 46-inch decks used on many residential riding mowers.

The part is ideal for owners who need a cost-effective alternative to dealer-priced spindles and want to return their mower to smooth, reliable cutting.

Which mower models and part numbers does this replace?

How do I know this spindle will fit my 46-inch deck?
