8TEN Blade Spindle Deck Kit for Ariens Gravely Ikon-XD ZTX ZT XL 52 Edge-52 52-Inch 04771200 51528000

What It Is

The 8TEN Blade Spindle Deck Kit is a complete replacement spindle assembly for 52-inch Ariens and Gravely zero-turn mowers. It’s designed to fix wobbling blades, bearing noise, or broken spindles, and includes the housing, bearings, shaft, and pulley pre-assembled for drop-in installation.

Fitment & Compatibility

• Deck size: 52-inch cutting decks only. Not compatible with 48-inch or 60-inch models.
• Models: Ariens Ikon-XD 52, Gravely ZTX 52, ZT XL 52, Edge-52, and Pro-Turn 52 with 52-inch fabricated decks (2015–2024).
• OEM cross-reference: Replaces Ariens/Gravely OEM part numbers 04771200 and 51528000.
• Measurements: Spindle shaft diameter is 1 inch; pulley diameter is 5 inches. Bolt pattern is 3 inches center-to-center with 5/16-inch bolts.
• Check before buying: Verify your deck has three spindle holes (left, center, right) and that your belt width is 1/2 inch or 5/8 inch. The kit does not include bolts or a belt.

Key Things to Know

• Build quality: 8TEN uses sealed bearings and a cast iron housing. Users report it’s slightly heavier than OEM but holds up well under heavy use.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench (bearings are pre-set), and a jack to lift the mower. Expect 45–60 minutes per spindle.
• Common gotcha: The pre-installed pulley may require a spacer (not included) if your deck uses a deeper pulley. Check your old spindle’s pulley depth before swapping.
• Warranty: 8TEN offers a 1-year limited warranty. Some users note bearing noise after 6 months in dusty conditions—grease zerk fittings are absent, so you can’t re-lube.

Should You Buy It

If you own a 52-inch Ariens or Gravely zero-turn and need a quick, ready-to-install spindle that matches OEM specs, this kit is a solid value at $143—especially compared to OEM spindles that run $80–$100 each (and you need three). It’s best for owners who want a one-stop replacement without sourcing bearings and housings separately. Skip it if you need a lighter-duty spindle for occasional use; the extra weight may strain the deck on smaller engines.
