This solid shaft is designed to completely replace your viscous coupler. If your V.C. is in need of replacement, it is a good time to upgrade to a drive shaft decoupler and this V.C. eliminator shaft. The installation of these two parts will give you the flexibility of 2WD highway performance and "on-the-fly" 4WD engagement. Ultra heavy-duty construction and bullet proof design will deliver a lifetime of performance for even the most hardcore off-roading.
This part can ONLY be used in conjunction with the drive shaft decoupler.
