Keep your in-wall slide-out moving smoothly with a direct-fit replacement roller. The Lippert 244838 is the OEM-specified J-33 roller assembly used in Forest River in-wall slide-out systems -- designed to restore proper travel, reduce binding, and protect the slide room floor and seals from the wear that a damaged or missing roller causes.
In-wall slide-out systems rely on a series of precisely sized rollers to guide the slide room in and out without dragging or binding. When a roller cracks, flattens, or goes missing entirely, the slide room can scrub against the floor track, damaging the room bottom, the slide seal, and the drive mechanism. Replacing the roller promptly is one of the lowest-cost ways to prevent a much more expensive repair.
The 244838 is identified by Forest River as part number J-33, making it a drop-in replacement that requires no modification to the mounting plate location or track geometry. The compact mounting plate bolts directly to the existing hole pattern in the slide frame, and the 1-inch OD roller seats into the track just like the factory original.
Cross-referenced as Forest River part J-33 for confirmed fitment in compatible in-wall slide systems without adaptation.
1" outer diameter, 0.33" inner diameter roller sized to the standard in-wall track profile for smooth, rattle-free travel.
Integrated 1-3/4" x 4" x 1.55" mounting plate -- roller and plate ship as one assembled unit, ready to bolt in.
Backed by a limited 1-year manufacturer warranty from Lippert, one of the largest OEM slide-out system suppliers in the RV industry.
In-wall (also called "in-floor" in some configurations) slide-out systems use a horizontal rack-and-pinion or cable-driven mechanism concealed within the RV wall structure. Rollers mounted at key points along the slide frame carry the weight of the room and guide it along the track as the motor extends or retracts the slide. Unlike room-bottom rollers that simply prevent floor scuffing, structural guide rollers like the J-33 directly affect alignment and load distribution during travel.
A worn or missing roller puts uneven stress on the drive motor, the rack gear, and the room seals -- symptoms include slow retraction, grinding noise during slide operation, or a slide room that does not sit flush when fully retracted. Replacing the roller restores the designed load path and typically resolves those symptoms immediately.
Replacing a slide-out roller is generally a straightforward job for an RV owner comfortable with basic hand tools, but safe practice requires fully retracting the slide room and disconnecting slide power before starting work.
