When your FR34 Class C slide-out stops extending or retracting smoothly, the motor is often the culprit. The Lippert 118816 Venture motor is the correct OEM-spec 28:1 replacement for Electric Single Rail Above Floor slide-out systems, including FR34 Class C Dual applications. Bolt-on fit means no fabrication, no adapter plates, and no guesswork -- just restored slide-out function.
The Lippert Venture motor family is the factory drive unit behind millions of Electric Single Rail (ESR) slide-out systems installed in Forest River, Coachmen, and other popular RV brands. Part number 118816 specifically targets the FR34 Class C Dual configuration, which uses an above-floor rail orientation requiring the 28:1 gear ratio to match the torque and speed profile of the original drive assembly.
Selecting the wrong motor ratio -- even from the same Venture family -- will cause the slide to move at the wrong speed, overload the controller, or fail to fully extend and retract. The 28:1 ratio in this unit is critical. Always verify your existing motor's ratio tag or the label on your slide-out control module before ordering.
Matched to the torque and speed requirements of FR34 above-floor single rail slide rooms. Not interchangeable with 40:1 or 72:1 variants.
Built for Electric Single Rail systems where the slide room mechanism rides on a rail mounted above the RV floor -- common in Class C coaches.
Lippert factory part number 118816. Mounts to the existing bracket and gear interface without modification or adapter hardware.
Specified for FR34 Class C Dual slide-out configurations. Verify your coach floor plan and slide system type before ordering.
Lippert Venture motors are available in multiple gear ratios -- typically 28:1, 40:1, and 72:1 -- each tuned to a different slide room size, weight class, and rail configuration. The 28:1 ratio delivers higher rotational speed with moderate torque, suited for lighter above-floor single rail rooms. Installing a mismatched ratio can damage the slide controller, strip drive gears, or cause incomplete travel. Confirm your ratio before replacing.
The Lippert Electric Single Rail slide-out system uses a motor-driven rack-and-pinion or acme screw mechanism mounted on a single horizontal rail beneath or beside the slide room. The Venture motor bolts directly to the drive unit and receives 12V DC power from the coach's slide-out controller. This design is common in Class C motorhomes and smaller Class A coaches produced from the mid-2000s onward.
