Parts arrived on time, quality and finish was fine, installation as easy as any top seal. The problem is that the claimed 2 inch travel was just over 2 1/2 inches. Put me higher in front than I wanted. To be fair I installed the 2 1/2" (given to me) which they increased by 3" first. Finished 1 3/4 inches which gave me only about 2 inches of the slight front bottom slope I was looking for. All were different brands. Manufacturers seem to lack precision.
