Genuine Lippert replacement motor manufactured by Tuson for Through-Frame electric slide-out systems. Exact OEM fit for 2x2 and 2.5x2.5 actuators with 24" or 40" stroke. Motor and gearbox assembly only -- actuator not included.
The Lippert 125802 is the genuine OEM replacement motor for Lippert Through-Frame electric slide-out systems. Manufactured by Tuson specifically for Lippert, this motor is an exact-match replacement for the original equipment installed at the factory. When your slide-out moves slowly, fails to extend or retract fully, or the motor makes grinding or burning smells, this is the direct-fit solution.
The 18:1 gear ratio delivers smooth, consistent slide-out operation with enough torque to drive large room slides reliably over thousands of cycles. It is compatible with both 24-inch and 40-inch stroke actuators used in the Through-Frame system architecture found across a wide range of Lippert-equipped towables and motorhomes.
High-torque gearing moves heavy slide rooms smoothly and reliably cycle after cycle.
Manufactured by Tuson for Lippert -- same motor that came in your RV at the factory.
Compatible with both 24" and 40" stroke Through-Frame actuators, 2x2 and 2.5x2.5 tube sizes.
Runs on standard 12-volt RV house battery power -- no inverter or shore power required.
Through-Frame slide-out systems route a steel actuator tube through the RV's frame rails to push and retract the slide room. The motor mounts to a gearbox that drives the actuator tube in and out. This design is common on mid-size and large travel trailers, fifth wheels, and some Class A motorhomes built with Lippert (formerly Kinro/LCI) chassis components. If your slide-out motor bolts directly to a gearbox housing mounted on the frame, and the actuator tube passes through the frame, you have a Through-Frame system.
This motor is designed for use with two actuator sizes common to the Lippert Through-Frame lineup:
Verify your actuator tube size and stroke length before ordering. The actuator assembly and slide-out room hardware are not included with this motor.
Lippert has produced multiple generations of Through-Frame slide-out systems. Confirm the following before purchasing:
This is a motor and integrated gearbox assembly. Replacement involves disconnecting the two-wire 12V harness, unbolting the motor from the actuator housing, and reversing the process with the new unit. Most DIY-capable owners can complete the swap in under an hour with basic hand tools. Torque the mounting fasteners to the gearbox manufacturer's specification. After installation, cycle the slide fully in and out at least twice to confirm smooth operation before loading the room.
