Direct replacement motor for Lippert Electric Through-Frame Venture Actuator slide-out systems. The 28:1 gear ratio delivers lower speed and higher torque compared to the 18:1 motor -- the correct choice when your slide-out carries heavier loads or requires extra drive force. Fits 2x2 and 2.5x2.5 Through-Frame actuator assemblies. Manufacturer internal reference 8532-08J.
Lippert's Venture Actuator system is a linear electric drive used in through-frame slide-out applications across a wide range of towable and motorized RVs. When the motor fails -- or when an upgrade to a higher-torque unit is needed -- part number 136373 is the factory-specified 28:1 replacement for 2x2 and 2.5x2.5 actuator frames.
The 28:1 ratio means the motor turns 28 times for every single output shaft revolution, multiplying torque significantly. This makes it better suited to larger or heavier slide-out rooms, multi-slide rigs where one motor handles a demanding run, or situations where the 18:1 motor has been marginal under load. Trade-off is a slower in/out cycle time relative to the 18:1 version -- both are intentional design choices by Lippert.
Higher torque output than the 18:1 motor. Better suited to heavier slide-out rooms and demanding actuator runs.
Runs directly off the RV house battery system. No inverter or converter modification needed.
Designed specifically for Lippert 2x2 and 2.5x2.5 Through-Frame Venture Actuator assemblies.
Matches OEM mounting and wiring configuration. No fabrication or bracket modification required.
Lippert offers two motor ratios for the Through-Frame Venture Actuator series. Choosing the wrong ratio means the replacement will not perform as intended, and in some cases the slide-out controller logic may not operate correctly.
Before ordering, check the label on your existing motor or the slide-out actuator assembly documentation to confirm which ratio your system uses. Installing a 28:1 motor in an 18:1 application (or vice versa) will result in incorrect slide travel timing.
This motor fits Lippert Electric Through-Frame Venture Actuator systems using 2x2 or 2.5x2.5 actuator tube dimensions. The 28:1 ratio must match the ratio stamped on your original motor. Manufacturer reference number: 8532-08J. Lippert part number: 136373.
The actuator tube dimensions (2x2 or 2.5x2.5 inches) refer to the cross-section of the outer drive tube that passes through the frame. These dimensions are typically stamped or labeled on the actuator housing. Both sizes use the same motor mount interface in this series, making part 136373 compatible with both.
Installing a motor with the wrong gear ratio will cause the slide-out to travel at incorrect speed. In worst-case scenarios this can trip the controller's overload protection or cause the room to stop short of full travel. Always match the ratio on the replacement to the ratio on the original motor.
