Lippert Components 28:1 Gear Ratio FR34 Class C Dual Fitment
Lippert 118816 -- Venture 28:1 Slide-Out Motor for Above Floor Single Rail Systems

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.

Direct Replacement Motor for Lippert Above Floor Slide-Out Systems

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.

28:1 Gear Ratio

Matched to the torque and speed requirements of FR34 above-floor single rail slide rooms. Not interchangeable with 40:1 or 72:1 variants.

Above Floor Single Rail Design

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.

OEM Replacement Fit

Lippert factory part number 118816. Mounts to the existing bracket and gear interface without modification or adapter hardware.

Class C Dual Application

Specified for FR34 Class C Dual slide-out configurations. Verify your coach floor plan and slide system type before ordering.

Why the Gear Ratio Matters

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.

Electric Single Rail (ESR) System Overview

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.

Verify Fitment Before Installing

Lippert produces many Venture motor variants for different slide systems. Confirm the following before installing this motor:

  • Your slide is an Electric Single Rail Above Floor type (not a rack-and-pinion under-floor or HappiJac system)
  • Your existing motor or system label confirms a 28:1 gear ratio requirement
  • Your coach matches the FR34 Class C Dual application
  • The motor mounting bolt pattern and output shaft interface match your existing drive assembly

Maintenance Tips for Long Motor Life

  • Lubricate the slide rail and gear mechanism at least once per season with a lithium or dry PTFE lubricant -- a dry motor fights excess friction and wears faster
  • Keep the slide seals clean to reduce drag and lower the load on the motor
  • After installation, cycle the slide fully in and out 2-3 times to seat the motor under load and confirm smooth, complete travel
  • Inspect the wiring harness connector at the motor for corrosion annually -- a high-resistance connection causes the motor to run hot and shortens its service life

Important Information

  • This motor is application-specific. The 28:1 ratio is required for FR34 Class C Dual above-floor single rail configurations -- do not substitute a different ratio motor, even from the same Venture family.
  • Always disconnect coach 12V power (or pull the slide-out fuse/breaker) before removing or installing the motor to prevent accidental slide movement during service.
  • This is a replacement motor assembly only. The slide rail, rack, controller, and wiring are not included.
  • If your slide-out controller has stored a fault code, clear and retest after motor replacement -- a failed motor can leave fault flags that prevent normal operation even after the motor is replaced.
  • If the slide room is stuck in or out, do not repeatedly cycle the motor in an attempt to force movement -- diagnose binding, obstruction, or rail damage before applying further motor load.
