I have use Monroe Magnums on every truck and Jeep I've owned for the last 30 years. The Rancho 9000's are a great shock but I could never get more than a few years out of them. Anything you buy in a standard gas shock will ride stiff on the highway if you hope to get any off road performance. Good luck with your purchase.
