Stens 265-803 OEM Replacement Belt/Cub Cadet 954-3055A

What It Is

The Stens 265-803 is an aftermarket replacement belt designed for the drive system on select Cub Cadet lawn tractors and zero-turn mowers, directly replacing OEM part 954-3055A. It transmits power from the engine to the cutting deck blades.

Fitment & Compatibility

Before buying, verify your mower’s model number (not just brand) against Stens’ fitment list. This belt fits Cub Cadet models like the LT1050, LTX1045, RZT50, and Z-Force S48, among others. Check your owner’s manual or the old belt’s part number to confirm it matches 954-3055A. Measure your old belt’s length (typically 96.5 inches) and width (1/2 inch) to double-check. Stens 265-803 is an aftermarket part, not OEM, but is built to OEM specs—use it only on machines requiring a 96.5" x 1/2" belt. Avoid using on decks with different pulley configurations.

Key Things to Know

• Quality: Made from EPDM rubber with aramid cord reinforcement; comparable to OEM in durability, often at a lower price.
• Installation difficulty: Moderate—requires removing the deck and routing the belt around pulleys, tensioner, and idlers. A diagram is helpful; take a photo of old belt routing first.
• Common gotchas: The belt may feel slightly tight on new pulleys—that’s normal. Ensure the tensioner arm moves freely and the spring is not worn. Replacing the belt without checking pulley bearings can cause premature wear.
• Lubrication: No lube needed; keep belt and pulleys clean of oil or grass buildup.

Should You Buy It

If you need a reliable, cost-effective replacement for a worn or broken deck drive belt on a compatible Cub Cadet mower, this is a solid choice. It’s not for bargain hunters who want the absolute cheapest option, but for most homeowners and light-commercial users, the Stens 265-803 offers OEM-like performance at a better price. Skip it only if you require a genuine Cub Cadet belt for warranty reasons or have a non-listed model.
