C27501-UG Upgraded Oilite bushing to replace . This is only for mid-generation 200-400 models and all 3000-4000 series. Look at the photo of the correct cross member steering support that this busing goes in. We ALWAYS replace this with a new shaft. Otherwise, new shaft and gear will wear fast, and steering performance will also suffer.
 
We highly recommend that when doing any steering shaft/gear work, replacement, or upgrade, you use our "Steering Shaft Install/Refresh kit." it can be seen HERE
 
A nice upgrade is our "STEERING SHAFT" Poor Mans Power Steering for under the steering wheel. The kit can be seen HERE
