A:Answer Hello Kitty. The Stacking Kit for Most 27" LG Washers and Dryers - Chrome, Model # KSTK1 is compatible with both the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Smart Wi-Fi Enabled Front Load Washer, Model # WM3700HWA and the LG Super Capacity (7.0 cu.ft.) Electric Dryer, Model # DLE1310W. The dryer was compatible with the 27" LG Laundry Stacking Kit, Model # WSTK1 which was replaced by the KSTK1. The only difference is the color. The WSTK1 was white and the KSTK1 is Chrome. We don't offer the stacking kit in different colors anymore. It is only offered in chrome...^IFV
