15 Tooth Gear 140409 Replacement Standard Gear Pack Assembly - Smooth

In this review of the 15 Tooth Gear 140409 replacement gear pack assembly the bottom line is simple: this part is for RV owners with through-frame slide-outs manufactured after October 2013 who need a direct, no-fuss replacement. The reviewer found it reliably engineered for its intended use and praised the fit and quiet operation. If you count 15 teeth and need a compatible component for Lippert-style systems, this assembly delivers the single biggest benefit: a precise, wear-resistant gear that installs without additional assembly and restores smooth slide-out movement.

Key Features

• Precision machined: Gear grinding produces a high-precision tooth profile that reduces backlash and contributes to quieter sliding operation.
• Wear resistance: Materials and machining improve longevity so the gear can continue working for many years under normal slide-out use.
• Direct replacement: The assembly arrives ready to install without extra assembly, matching original equipment form for an easy swap on the track.
• Compatibility note: Designed for Lippert through-frame slide-outs manufactured after October 2013, it replaces the common 15-tooth configuration used in those systems.
• Low noise performance: The combination of precision grinding and fitment yields smoother, quieter slide-out operation compared with worn gears.
• One-year warranty: A one-year warranty provides short-term protection and reassurance for the replacement part.

Who It's For

This part is best for RV owners, repair technicians, and DIYers who have a through-frame slide-out showing signs of wear, grinding, or rough movement and who have confirmed a 15-tooth gear is required. It suits installations where quick, direct replacement on the track is important and where compatibility with Lippert-style systems after October 2013 is needed.

It is not the right choice for owners whose slide-outs use an 18-tooth gear or who have units manufactured before October 2013; those systems require a different gear. Also, the assembly does not include a roll pin, so purchasers should confirm they have any small retention hardware on hand.

Pros & Cons

Pros

• Machined by gear grinding for precise tooth geometry and reduced noise.
• Reported by customers to fit properly and match gear packs for a straightforward replacement.
• Wear-resistant construction intended to provide reliable service over time.
• Ready-to-install assembly that eliminates final assembly steps.

Cons

• Not compatible with slide-outs manufactured before October 2013 that use 18-tooth gears.
• Replacement does not include a roll pin, so a small part may be needed separately.

Frequently Asked Questions

How do I confirm this is the correct gear?
Count the number of teeth on your existing gear; this part requires 15 teeth and is intended for systems made after October 2013.

Does the assembly include all small hardware?
The assembly does not include a roll pin, so you should have any small retention hardware available before installation.

Will this work on older Lippert systems?
No; slide-outs manufactured before October 2013 typically use an 18-tooth gear and need the corresponding replacement.
