I replaced one Spindle on my Hustler Sport Zero Turn, this was a perfect fit. Solid, heavy, appears well built.Only extra comment -- no replacement bolts provided (many youtuber's broke them removing); I didn't break any (whew). Could add as an Extra for $2.00 to include Bolts? Approx 5/16 x 2 inch, hardened; 9/16 bolt & nutWorks great, was easy to replace; will use this seller, this item again if I need to replace 2 or 3 on my Zero Turn. Much quieter now.Oh, one extra thing that was included, rarely seen from Amazon -- a Packing slip!
