JYLEYJ Spindle Assembly 54" Mower Deck Replacement 3-Pack — Direct-Fit OEM 918-06978, Precision Shaft

This is a 3-pack of JYLEYJ replacement spindle assemblies engineered to restore cutting performance on 54-inch mower decks for Cub Cadet, Troy-Bilt, Craftsman and compatible models.

These aftermarket spindle assemblies are made as direct-fit replacements for worn or damaged original units on 54" decks. Each spindle in the set matches the OEM mounting pattern and shaft dimensions commonly used across multiple riding mower lines, letting you swap them in with standard tools. The pack includes three identical spindles so you can service an entire 54-inch deck at once and get blades spinning true again.

How do these spindles restore my mower's cutting performance?

Worn or bent spindles cause vibration, uneven cuts, and rapid blade wear. Installing new assemblies returns the blade alignment and rotational stability that the deck needs for an even, consistent cut.

• Replaces OEM numbers 918-06978 and 618-06978 for direct fit
• Precision-machined spindle shaft for correct blade tracking
• Reduces vibration and blade wobble for cleaner stripes
• Three spindles included to service all three deck positions

Will these parts fit my specific mower model?

These assemblies are designed to fit many 54" decks from major brands. They match bolt patterns and shaft sizes used on popular Cub Cadet RZT, XT, and ZT series, MTD/Craftsman 5400-series decks, and several Troy-Bilt 54-inch models—check your OEM number or compare measurements before ordering.

• Compatible with Cub Cadet models like ZT1-54, ZT2-54, XT1/XT2 series
• Fits MTD/Craftsman decks such as T8400, G8400, G8600 families
• Works with Troy-Bilt TB2454 and Mustang 54 series
• Cross-references OEM 918-06978 / 618-06978 and Stens 285-705

What do I need to install these spindle assemblies?

Installation requires basic hand tools and safe access to the mower deck. Typical steps include removing the deck, detaching blades, unbolting the old spindle, aligning the new unit, and re-torquing fasteners to manufacturer specs.

• Tools: socket set, torque wrench, blade holder, jack or ramps
• Time: roughly 45–90 minutes per spindle for most DIYers
• Tip: replace all three spindles at once to balance blade height and performance
• Reference: check mower manual for torque values and safety procedures
