8TEN Spindle for Cub Cadet Troy Bilt XT1-LT50 Super Bronco 50 XP 50-Inch Deck 618-09255 618P09255 3 Pack

What It Is

This is a 3-pack of aftermarket spindle assemblies designed for Cub Cadet and Troy-Bilt lawn tractors with a 50-inch fabricated deck. They replace the OEM part numbers 618-09255 or 618P09255, which are the original spindles that hold the blades and allow them to spin freely.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch fabricated deck (not stamped). These fit specific models including:

• Cub Cadet XT1-LT50, XT2-LX50, XT3-GS50
• Troy-Bilt Super Bronco 50 XP, Bronco 50
• Some RZT, ZT, and Z-force zero-turn models with 50-inch decks

Measure your old spindle housing height (top to bottom) and bolt pattern (typically 4-bolt with 3-inch spacing). Check that your blade bolt size matches (usually 5/8-inch). These are aftermarket, not OEM, so verify deck model number on your mower’s deck sticker—common decks include 50A, 50F, or 50-inch fabricated.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic tools (socket set, wrench, jack) and about 1-2 hours per spindle. Expect to remove the deck and belt.
• Quality note: 8TEN is a budget aftermarket brand. Some users report shorter bearing life compared to OEM, but they’re fine for occasional home use.
• Common gotcha: The included grease fittings may be tight; pre-grease before installation. Also, check that blade alignment is correct after install—off-center blades can cause vibration.
• Warranty: Typically 1-year limited, but check seller specifics. No OEM support.

Should You Buy It

This 3-pack is a good value for a homeowner replacing all three spindles at once on a 50-inch deck. If you need a quick, cost-effective fix and aren’t running a commercial mower, it works. But if you want longer-lasting OEM reliability for heavy use, stick with genuine Cub Cadet spindles (often $40-60 each).
