LippertPart No. 197840XT Slide SystemLippert 197840 XT Rear Slide Track Assembly

Keep your slide room moving smoothly with this OEM-grade rear track assembly engineered specifically for Lippert XT slide-out systems. When the rear track wears, bends, or breaks, the entire slide room can bind, rack, or refuse to extend and retract correctly. This direct replacement restores proper alignment and smooth travel so your slide operates the way it was designed to.

Direct OEM Replacement for Lippert XT Slide-Out Systems

Lippert is the largest manufacturer of RV slide-out systems in North America, and the XT system is one of their most widely deployed designs. The rear track is a critical structural and mechanical component -- it guides the slide room as it extends and retracts, and it bears a significant portion of the room's weight and lateral load. A damaged or worn rear track causes uneven movement, weather seal problems, and can eventually damage the slide room frame itself.

Part number 197840 is the rear track assembly designed to match the original Lippert factory specification for XT-series slide rooms. Using the correct OEM part number ensures proper fit without modification to the slide room frame or drive mechanism.

OEM Part Number Match

Part 197840 is a Lippert factory-spec component, ensuring correct fitment to XT slide systems without modification or shimming.

Rear Track Function

The rear track guides and supports the slide room at the back of the opening, keeping the room level and aligned during extension and retraction.

XT System Compatibility

Designed specifically for Lippert XT slide-out systems -- one of the most common slide platforms in fifth wheels and travel trailers built from the mid-2000s onward.

Structural Replacement

Replaces a worn, bent, or broken rear track to restore smooth, rattle-free slide room operation and proper weather seal contact.

Is This the Right Part for Your Slide?

The Lippert XT slide system is a rack-and-pinion style slide common in many Forest River, Coachmen, Keystone, and other brand trailers and fifth wheels. The XT designation refers to a specific generation of Lippert's slide drive mechanism. Before ordering, confirm:

  • Your slide system is identified as a Lippert XT on the drive assembly label or your coach's parts list.
  • You need the rear track (not the front track or side rails).
  • Your coach's build records or the existing track show part number 197840 or reference this assembly.
Tip: The track label or a Lippert service diagram for your coach's build date and floor plan is the most reliable way to confirm this is the correct track before installation. Your RV's VIN can be used to pull Lippert's component records.

Installation Overview

Replacing a rear slide track is a moderate-difficulty repair typically performed with basic hand tools. The slide room will need to be fully retracted or supported during replacement. Key steps generally include:

  • Retracting the slide room fully and disconnecting power to the slide motor.
  • Removing the old rear track hardware and detaching any retaining brackets.
  • Installing the new 197840 track assembly and torquing fasteners to Lippert specification.
  • Cycling the slide room slowly and checking for smooth, even travel before returning to service.
Heads Up: Slide-out track replacement should be performed with the coach on level ground and the slide room properly supported. Incorrect installation can cause racking, seal damage, or drive motor failure. If you are not familiar with Lippert slide systems, professional service is recommended.

Common Symptoms of a Worn or Failed Rear Track

  • Slide room moves unevenly or one corner lags behind the other during extension or retraction.
  • Unusual grinding, popping, or squealing from the rear of the slide opening.
  • Slide room does not fully seat against the coach body, causing a gap in the weather seal.
  • Visible bending, cracking, or wear on the existing rear track rail.
  • Increased amp draw or motor stalling on retraction.
Maintenance Note: After installing the new track, lubricate all sliding contact surfaces with a dry PTFE or sillithium slide-out lubricant. Avoid petroleum-based greases that attract dirt and accelerate wear on track surfaces.

  • This is the rear track assembly only. Front tracks, side rails, and drive components are sold separately.
