Something to think about. If you upgrade your tie rod ends and not your steering rack you could pass on damage from the ends to the rack.
I believe this is why Rhino owners are busting racks, the tie rods are designed to fail before the rack.
We just starting carrying a HD rack for the Rhino and the manufacturer uses heim joints for tie rod ends. They stated the heim joints are designed to fail before the rack just like the stock stuff but of course the whole system is heavier duty.
