8TEN LawnRAZOR Blade Spindle Kit for Cub Cadet XT2-SLX50 XT2-GX50 50 Inch 942-01050-H 918-07384A

What It Is

The 8TEN LawnRAZOR Blade Spindle Kit is a replacement spindle assembly for 50-inch Cub Cadet XT2-SLX50 and XT2-GX50 lawn tractors. It houses the blade mounting pulley, bearings, and shaft, enabling the blade to spin freely and cut evenly.

Fitment & Compatibility

• Deck size: 50-inch cutting deck only. Do not use on 42-inch or 46-inch models.
• Models confirmed: Cub Cadet XT2-SLX50, XT2-GX50 (check your model tag under the seat).
• OEM cross-references: Replaces Cub Cadet 942-01050-H and 918-07384A. Verify your old spindle part number before ordering.
• Measurements: Spindle shaft diameter is 5/8-inch; bolt pattern is 3-bolt triangular with 3.25-inch spacing. Measure your old spindle to confirm.
• What to check: Deck thickness—this kit fits standard stamped steel decks, not fabricated or heavy-duty decks. Also confirm spindle pulley diameter matches your belt (typically 4.5 inches).

Key Things to Know

• Quality: 8TEN LawnRAZOR uses sealed ball bearings and a hardened steel shaft. Expect comparable lifespan to OEM, but not superior.
• Installation: Moderate difficulty (requires removing deck, belt, and blade). Have a torque wrench—spindle bolts need 35–45 ft-lbs. Do not overtighten.
• Common gotcha: The included grease fitting is pre-installed. Do not add grease until after first 5 hours of operation to avoid over-packing bearings.
• Compatibility note: This kit does not include a blade or pulley belt. Reuse your original pulley if it’s in good shape, or buy separately.

Should You Buy It

Buy this if you have a 50-inch XT2-SLX50 or XT2-GX50 with a failed spindle (noisy, wobbling, or seized) and want a reliable, budget-friendly alternative to OEM at roughly half the price. Skip it if you need a full deck rebuild kit or have a different deck size.
