We ordered this kit, as it was shown as a replacement for the side mounted supports that contain the rollers for the upper rack. Got the kit an panicked at first as it was nothing like what was on our rack, but then slowly examined the new parts, watched the installation video that uses a KitchenAid rack, and figured out it would work. Toughest part was figuring out how to remove the old wheel supports/height adjuster, but once that cam off, the rest was pretty easy. Plus, the kit has sturdier metal brackets rather than plastic ones, so it seems it'll last. Very happy with the results. Shipping was very quick, with the parts arriving in 2 days using standard shipping. Excellent experience!
