After lifting your Jeep JK Wrangler 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.
