Keep your RV slide-out rolling smoothly with this genuine Lippert replacement rear roller shaft. Designed specifically for electric 2.5 x 2.5 through-frame slide-out systems, this cold-rolled steel shaft is a direct OEM-spec replacement that restores proper roller function without the guesswork of universal substitutes.
The Lippert 105892 rear roller shaft is a maintenance and repair part for owners of RVs equipped with Lippert electric through-frame slide-out mechanisms. Through-frame slide-outs route the slide room through the main structural frame rails of the coach, and the rear roller shaft is a critical component that supports and guides the slide room as it extends and retracts.
When a roller shaft becomes bent, corroded, or worn, the slide room may bind, travel unevenly, or make grinding noise during operation. Replacing the shaft with an OEM-spec part is the correct fix -- not adjusting the motor or controller. This shaft ships at 2 lbs, making it straightforward to handle and install without specialized lifting equipment.
Formed from cold-rolled steel for consistent dimensional accuracy and resistance to bending under the lateral loads a slide room generates during travel and use.
Matches Lippert factory specifications for 2.5 x 2.5 through-frame electric slide-out systems, eliminating the need for modification or shimming.
Listed under Lippert manufacturer reference LSS0019B and Keystone RV part number 221383, making identification straightforward for Keystone coach owners.
At 2.5 inches in length, this shaft is dimensioned to drop into the OEM mounting position without trimming or adaptation.
In a through-frame slide-out system, the slide room sits on a set of rollers that ride along the frame rails. The rear roller shaft is the axle pin on which the rear support roller pivots. If this shaft shears, corrodes, or wears out of round, the roller can seize or fall out of alignment, causing the slide to rack or drag. Replacing just the shaft -- rather than the entire roller assembly -- is typically the most cost-effective repair when the roller itself is still serviceable.
This shaft is designed for electric 2.5 x 2.5 through-frame slide-out systems manufactured by Lippert Components. The "2.5 x 2.5" designation refers to the through-frame rail profile used in the slide mechanism. Verify your system type by checking the label on your slide-out motor housing or the Lippert tag affixed to the slide mechanism inside the bay.
Replacing the rear roller shaft typically requires retracting the slide room fully, supporting the slide room from below to relieve load on the roller, removing the old shaft, and pressing or sliding the new shaft into position through the roller bore. Retaining clips or fasteners from the original installation are often reusable if undamaged. Inspect the roller itself for flat spots or cracking while the shaft is out.
