Not sure of the rating. They changed depending on installed equipment. BUT, I can tell you NOT to buy them from Eaton Detroit Spring. Their "claim to fame" self proclaimed I'm sure... is that they use factory blueprints to twist their wire. After a few conversations with their sale rep, I ordered a set for my bird. When they arrived, they were one inch shorter than the original springs. I contacted the sales rep and his statement was that they use a heavier wire than stock so the spring is shorter. Long story short, sort of, I installed those springs and the car sat over 4 inches TALLER than original ride height. I have the manuals. His stance now is to wait until we drive the car to get a feel for the "actual ride height"... I pulled those springs into the pockets with the spring compressor. If they're not seated, they never will be...
