A slide-out that won't extend or retract usually comes down to one failed component, and this Klauber D-300 motor from Lippert is a genuine replacement built specifically for through-frame slide-out systems. It ships as the motor assembly only, so you're replacing exactly what failed rather than the entire slide-out mechanism.
Running on 12V DC at 12 RPM with a 3/4" drive, this motor is engineered as an exact-match component for compatible through-frame slide-outs, which keeps installation straightforward with no additional assembly required. It's backed by a 1-year warranty.
Check your owner's manual or your slide-out's existing motor before ordering to confirm this D-300 is the correct match for your specific through-frame system.
