Review on Upgraded HD Switch 6 Pack Spindle Rebuild Bearings - Compatible Replacement for Hustler 783506 🔧 Mini Z FasTrak FasTrak SD TrimStar Super Mini Z, enhanced with High Temperature Grease & C3 Upgrades by Brian Henley

Perfect for my Hustler 54" Fastrak. Installation was easy. I found it easier to remove the top bolt, lower the blade and shaft, then unscrew the 4 bolts and the spindle I used my vise to knock out and install the new bearings then reassembled them on deck.Checked the next day all was smooth and quiet.Only time will tell how long they last.
