Lippert 281331 Slide-Out Gear Pack 2″ x 2″
This genuine Lippert replacement part is designed specifically for Through-Frame slide-outs. It includes the gear pack only, not the complete assembly. Best for owners who want an authentic Lippert component and a straightforward fit. Use when your manual confirms a 15-tooth 2×2 gear match. Avoid if your system is pre-October 2013 and requires 18-tooth gearing unless verified by the model number.
Aaiov 700612 Replacement 15 Tooth Spur Gear
Best for users who need a 15-tooth spur gear compatible with Lippert slide-out systems across multiple frame configurations (2×2, 2.5×2.5, 2×3, and 3×3). The gear is machined for wear resistance, offering high precision and lower noise during operation. Choose this when the model number confirms compatibility with 281331, 140409, 324869, or 123356 variants. Caution: confirm that your system uses a 15-tooth configuration, not an 18-tooth, before purchasing.
Misakomo 15-Tooth Gear Pack Assembly
Best for campers seeking a 15-tooth, rust-resistant gear pack to restore smooth operation of a sliding tubed arm. It claims easy direct replacement with no additional hardware required and improves longevity. Use when the main slide is prone to sticking due to gear wear. Limitations include verifying the exact gear count and fit for your frame size, as mismatches can cause misalignment.
Aaiov 122739 Replacement 18 Tooth Gear
Best for 18-tooth configurations found in Lippert slide-out systems installed before October 2013. This gear supports exact-match DIY installation. It is a practical choice when you confirm an 18-tooth requirement; otherwise, opting for a 15-tooth alternative could cause improper engagement. Caution: confirm tooth count before ordering to avoid incorrect gear type.
BuliBoao Slide Out Motor Gear (18:1)
Best for RVers needing a direct motor gear replacement to repair stripped Lippert Tuson Venture motors. The 18:1 metal gear provides a robust solution with easier installation. Choose this when a metal gear upgrade is preferred over a full motor replacement. Limitation: ensure your motor gear ratio matches 18:1 to guarantee compatibility.
Zreneyfex 18:1 Ratio Gear for RV
Best for budget-conscious repairs requiring an 18:1 ratio metal gear. It’s a practical option to repair an actuator while avoiding full motor replacement. The gear is designed to fit Lippert Tuson Venture systems and similar through-frame configurations. Caution: verify the exact model compatibility and shaft dimensions before purchase.
Buying Guide
- Compatibility: Always verify tooth count (15 vs 18) and the frame size (2″ x 2″, 2.5″ x 2.5″, etc.) with your RV’s model manual.
- Material and durability: Metal gears typically offer longer life and resistance to wear and corrosion compared with basic plastic alternatives.
- Installation ease: Some gears are sold as direct replacement parts with no additional hardware; others may require minor modifications.
- Fuel and maintenance considerations: Replacing worn gears can prevent longer-term damage to slide-out mechanisms and reduce the risk of sticking during retraction or extension.
- Repair vs. replacement: For severely damaged motors, a single gear replacement may be cost-effective, while complete motor replacement might be necessary for large failures.
FAQ

A: An 18:1 ratio is designed for certain motor assemblies; confirm compatibility with your system before upgrading. - Q: Can I use multiple brands interchangeably?
A: Brand-specific fit and tolerance can vary. Use the parts that match your model’s documentation to ensure proper engagement. - Q: What maintenance helps extend gear life?
A: Regular inspection for rust, lubrication where recommended, and addressed wear at the earliest signs of stiffness can extend life.
