Restore smooth, reliable slide-out operation with the Lippert 379060 Standard Bearing Block Repair Kit. Designed specifically for RV in-wall slide-out systems, this kit includes the top and bottom bearing blocks needed to repair one side of a worn or damaged slide. A direct-fit solution cross-referenced by Jayco, Keystone, and Winnebago, so you can get your slide working again without guessing on compatibility.
Bearing blocks are the wear components in Lippert in-wall slide-out systems that guide and support the slide room as it extends and retracts. Over time, constant cycling causes these blocks to wear, crack, or deform -- resulting in uneven slide movement, binding, grinding noise, or a room that no longer seals flush against the sidewall. Replacing the bearing blocks is typically a fraction of the cost and effort of replacing an entire slide mechanism.
The 379060 kit is the factory-specified repair solution for this system and is cross-listed under multiple OEM part numbers, making it a reliable choice for owners of Jayco, Keystone, and Winnebago coaches built with Lippert in-wall slide systems.
Kit contains both the upper and lower bearing blocks required to fully rebuild one side of the slide-out channel.
Listed under Jayco 0282096, Keystone 497493, and Winnebago 18492301702 for confirmed fitment on factory-installed systems.
Engineered for Lippert in-wall slide-out architecture -- not interchangeable with under-bed or cable-driven systems.
New bearing blocks re-establish correct slide alignment, reducing bind, noise, and seal wear caused by degraded original blocks.
Lippert's in-wall slide-out system routes the slide room along a set of tracks mounted within the RV's sidewall structure. Bearing blocks ride along these tracks and carry the lateral and vertical load of the room as it moves. Unlike rack-and-pinion or hydraulic systems, in-wall systems rely heavily on the integrity of these blocks to maintain alignment. When blocks fail, the slide can rack (twist), drag, or develop a gap at the seal -- all signs that a bearing block replacement is overdue.
This kit is factory-verified for use on coaches from the following manufacturers where a Lippert in-wall slide system was installed:
If your slide was manufactured by Lippert (LCI) and uses an in-wall configuration, verify the original bearing block style (standard vs. heavy-duty) before ordering. The 379060 is the standard-series block.
Bearing block replacement on an in-wall slide typically requires extending the slide fully to access the track assembly from inside the coach, removing any trim or fascia covering the slide mechanism, and unbolting the worn blocks from the track. Lippert publishes service instructions for this system family through their dealer portal. Key tips for a successful repair:
