Perfect for 1954 Hudson Hornet. Installed without any changes. As I have other work and the car is not running I will update the information when I drive it. Suppose Revain lets you update the rating. I can say these shocks seem to be of a much higher quality compared to the Monroe shocks he replaced. Why? 1) Unlike the Monroe, they have an all-steel stem protector to protect against damage to the stem and subsequent internal seals. 2) They included 2 nuts for each attachment point, which prevented a nut from unexpectedly loosening on each attachment point Monroes came with. Also, I used the KYB app to check the compressed and expanded lengths, as well as the apps listed and cross referenced to other shock numbers. Definitely a very good app. The only downside is that the instructions are an odd collection of photos and not written words.
