Keep your RV slide-out running true with this OEM-replacement adjustable plate designed for Lippert LCI head assemblies. Compatible with both 2 x 2 and 2.5 x 2.5 electric and hydraulic through-frame slide-out systems, this plate restores proper slide travel and alignment when the original has worn, cracked, or been damaged during operation.
The adjustable plate is a critical component in the Lippert LCI through-frame slide-out system. It mounts to the head assembly and provides the adjustable interface that keeps the slide room synchronized and properly aligned as it travels in and out. Over time, these plates can develop wear or damage from the repetitive loading and side forces inherent in slide-out operation.
This Lippert part (manufacturer PN 104851, vendor PN 71-5524) is a direct OEM replacement. It is also cross-referenced as Keystone RV part number 145728, making it a confirmed service part for Keystone-built coaches equipped with LCI through-frame slide systems.
Direct replacement for Lippert LCI head assemblies -- no modification required for correct-application systems.
Fits both 2 x 2 and 2.5 x 2.5 through-frame slide-out configurations, electric or hydraulic.
Listed as Keystone RV PN 145728 -- a confirmed service replacement for Keystone coaches with LCI slide systems.
Approximately 2 lbs., making installation manageable for a single technician working under the coach.
Lippert LCI through-frame slide-out systems use a rack-and-pinion or hydraulic mechanism that runs through the frame rail of the RV. The head assembly is the mechanical interface at each end of the slide tube -- it guides the slide room, transfers drive force, and allows for adjustment to level and align the room. The adjustable plate is part of this head assembly and enables the lateral and vertical fine-tuning that keeps slide seals tight and room edges flush with the coach body.
Replacing the adjustable plate generally involves retracting the slide room fully, accessing the head assembly at the affected end of the slide tube, removing fasteners securing the worn plate, and installing the replacement. After installation, slide alignment and adjustment should be verified and corrected as needed per Lippert LCI service procedures.
