Kf04050bf I wanna say? It's on their website if you search it under the 2008-2010 Ford F-250/350 trucks, It is smaller height wise but does not compress like the oem ones do. The only gripe I have is they are smaller and the slotted hole is bigger on the chassis than the mount so when it's installed initially it will slide around, once torqued down though they don't move. I couldn't replace my 3rd from the rear on both sides so I left them installed, I greased the cab mounts cab and reinstalled them with antisieze on the bolts so they won't be a bitch to remove when I need to again. Hope this answers your questions, I did one side at a time and torqued it then moved to the other, the truck was on the ground the entire time. I used a 3 ton floor jack and a 4x4 that was 4 ft long to raise the cab close to the mount I was replacing. With the exception of the front two nuts that decided to spin everything was easy. Don't use an impact like everyone suggests.
