If your Whirlpool, Maytag, Amana, or Kenmore-brand top load washing machine is shaking violently and nothing else will fix it, our shim kit is engineered to help solve this problem. Our shims are constructed of high-quality, water-resistant 316 stainless steel. They are designed to tightly fit over the gearcase and splines, while accounting for the variable wear patterns experienced by your unique gearcase and tub situation. The kit comes with 3 rings of identical height and width and internal diameter. However, each ring has a different wall thickness to account for potential variances in your tub's wear pattern.
