Get your slide-out moving smoothly again without replacing the entire mechanism. The Lippert 366120 supplies the hardware needed to restore one side of an electric in-wall slide-out system -- the rollers, shoes, fasteners, and foam pads that take the most wear over time. If your slide is binding, dragging, or making noise on one side, this kit gives you the parts to fix it right.
Lippert's in-wall slide-out systems use an inverted rack-and-pinion design where the rack mounts above the slide room on the interior wall. Over miles of road travel and repeated extension cycles, the rollers, shoes, and mounting hardware wear down -- causing the slide to bind, ride unevenly, or develop play on one side. The 366120 repair kit is purpose-built to address exactly that.
This kit covers one side of the slide mechanism. For a full two-side restoration, two kits are required. Note that the racks themselves are sold separately -- this kit supplies the supporting hardware components only.
Replacement rollers with integrated bearings maintain smooth, low-friction slide travel and resist the side loads common to in-wall rack systems.
Wear shoes cushion and guide the slide room along the track, reducing metal-on-metal contact and preventing premature rack wear.
All required fasteners are included so you are not making a separate hardware run mid-repair.
Foam pads are part of the kit, providing the vibration dampening and sealing interface that keeps the slide room tight and rattle-free.
The inverted rack design is specific to Lippert's in-wall (also called through-wall) electric slide-out systems, which route the rack mechanism inside the wall structure rather than beneath the floor. This system is common on many mid-size and large travel trailers and fifth wheels from the early 2000s onward. If you are unsure whether your slide uses this mechanism, check the Lippert tag on the slide motor or measure the rack -- in-wall systems route the rack horizontally inside the upper portion of the slide opening.
The 366120 kit contains:
The kit does not include the inverted racks themselves. If your racks are damaged or stripped, they must be ordered separately by measuring rack pitch and length. Contact Lippert or cross-reference your coach's slide-out label for the correct rack part number.
This is a DIY-accessible repair for owners comfortable working with their slide-out mechanism. General steps include extending the slide to access the rack area, removing the old rollers, shoes, and worn foam pads, and installing the new components with the provided screws. Lippert's service documentation for in-wall slide-out systems (available through Lippert's owner portal) covers torque specs and alignment procedures. Proper alignment after reassembly is important -- a misaligned roller can accelerate rack wear.
