After lifting your Jeep YJ a CV (Double Cardan) drive shaft is a good choice to eliminate vibration issues and provide the longest lasting drive shaft
Includes Brute Force Red seals
Includes better quality CV joints
Shaft strength is twice as strong as the factory equipped drive shaft
Grease fittings are out of the way of the transmission oil pan meaning you get grease to the joints that need it and not all over the bottom of your Jeep
