Rough Country 5090.1A Jeep Front CV Drive Shaft 18-21 Wrangler JL Dana 30

Collapsed Measurment: 36 3/8 inches Extended Measurment: 39 1/2 inches Eliminates facotry driveshaft damage at full droop Works on Dana 30 axles ONLY 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 botom of your Jeep. An aftermarket driveshaft is HIGHLY RECOMMENDED for installation of any Jeep JL lift kit 3.5” or taller. The factory driveshaft will become damaged if the suspension reaches full droop or flex. ONLY fits Dana 30 front axle models. Recommended on models with 3.5in or more of lift.
