Genuine LG AHC73575003 Dishwasher Rail Assembly — the track system that guides your dishwasher's racks smoothly during wash cycles. Over time, rails can wear, warp, or accumulate debris, causing racks to stick or derail. This OEM replacement restores proper alignment and gliding action, ensuring reliable performance and protecting your dishes from damage during operation. Direct fit for compatible LG dishwasher models. Installation typically requires removing the lower rack and securing the assembly with existing fasteners.
