If your RV slide-out is jamming or grinding when it moves, a worn or broken spur gear is a common cause. This replacement gear is machined for wear resistance and matches the 18-tooth spec used in Lippert through-frame slide-out systems, including units built before October 2013 that used part numbers 123356 or 122837.
Count the teeth on your existing gear before ordering to confirm you need the 18-tooth version rather than the 15-tooth alternative, since the two are easy to mix up.
