ACEBRI Spindle Assembly fit for Cub Cadet for MTD for Troy-Bilt 618-06979 918-06979 for Stens 285-706 for Cub Cadet XT1-LT54 XT2-LX54 Mower Spindle 3 Pack

What It Is

This is a set of three spindle assemblies designed for zero-turn and lawn tractor mower decks, primarily for Cub Cadet, MTD, and Troy-Bilt models. It’s a direct replacement part for the OEM spindle assembly (part #618-06979 / 918-06979) and also cross-references with Stens 285-706.

Fitment & Compatibility

Before buying, verify your mower’s deck size and model. This 3-pack fits Cub Cadet XT1-LT54 (54-inch deck) and XT2-LX54 (54-inch deck), plus many MTD and Troy-Bilt tractors with similar spindle spacing. Measure your existing spindle’s bolt pattern and shaft diameter (typically 1-inch shaft with 5/8-inch bearing bore). Check your deck’s spindle hole spacing—this assembly uses a 3-bolt pattern. Cross-reference your OEM part number: 618-06979 or 918-06979. If your mower uses a different spindle (e.g., 42-inch deck or different bearing size), this won’t fit.

Key Things to Know

• Aftermarket quality: This is a non-OEM replacement. While rated 5.0/5 (2 reviews), inspect the bearings and housing for burrs or rough spinning before installation.
• Installation difficulty: Moderate. You’ll need a socket wrench, jack stands, and possibly a puller to remove old spindles. Expect 1–2 hours for all three.
• Common gotcha: The shaft may have a slight taper or flat spot for a pulley keyway—ensure your mower’s pulley matches. Also, check that the spindle housing depth matches your deck’s thickness (usually 0.125-inch steel).
• Warranty: No mention of a warranty; aftermarket spindles often have limited support. Buy from a seller with a return policy.

Should You Buy It

If you own a Cub Cadet XT1-LT54 or XT2-LX54 (or compatible MTD/Troy-Bilt model) with a 54-inch deck and need to replace worn spindles, this 3-pack is a budget-friendly option. It’s not ideal for heavy commercial use or older decks with non-standard bolt patterns. For the price, it’s a solid value if you confirm fitment and are comfortable with basic mechanical work.
