8TEN Spindle Set for Cub Cadet Ultima ZT1-60 ZTS2-60 ZT2-60 ZT3-60 FAB 60-Inch Deck 918-04822B 618-04889 3 Pack

What It Is

This 8TEN spindle set (3-pack) replaces the factory spindles on Cub Cadet ZT1-60, ZTS2-60, ZT2-60, and ZT3-60 zero-turn mowers with a 60-inch fabricated deck. It drives the blades via the belt and pulley system, and is designed for residential or light commercial use.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch fabricated (FAB) deck – this set does not fit stamped decks. Check your OEM part numbers: 918-04822B or 618-04889 (often found on the old spindle housing or in your manual). Measure the spindle shaft diameter (should be 1 inch) and pulley bolt pattern (3-bolt, 3-inch center-to-center). This is an aftermarket replacement, not OEM Cub Cadet, so verify the pulley height matches your belt path – some users report needing to swap the pulley from the original spindle.

Key Things to Know

• Assembly required: You’ll need to transfer the pulley, bearing housing, and hardware from your old spindles – this set comes as bare spindles only.
• Installation difficulty: Moderate. Requires basic tools (socket set, torque wrench, grease gun) and about 1–2 hours for all three. Threadlocker on mounting bolts is recommended.
• Quality note: 8TEN uses sealed bearings, but some users note the grease fittings are absent – you may want to add a small amount of grease during install.
• Common gotcha: The bolts holding the spindle to the deck can be seized. Use penetrating oil and impact driver to avoid stripping.

Should You Buy It

If your Cub Cadet 60-inch FAB deck spindles are worn (noise, wobble, blade imbalance) and you’re comfortable with basic mechanical work, this 3-pack saves roughly 30–40% vs. OEM. It’s a solid value for DIY homeowners who want to restore cutting performance without paying dealer prices. Not recommended if you need plug-and-play with pre-installed pulleys.
