DRIVESHAFT FRONT CV, RUGGED RIDGE, JEEP WRANGLER (JK) 07-10 2-DOOR OR 4-DOOR New original equipment JK Wranglers use drive shafts that have Rzeppa CV joints similar to most front wheel drive cars. These CV joints are fine for normal car applications but when you lift your Jeep or put on larger tires and drive your Jeep off road, these joints are not up to the task! Rugged Ridge has developed a solution for this problem with doubleûcardan joint drive shafts for the JK Wrangler. These double U-joints provide better strength and operating angle and reduce vibration on lifted Jeeps. Each drive shaft has increased tube thickness and standard slip yokes for long life and easy of installation. All are a direct bolt on attaching to the stock axles and transfer case without any modifications. All U-joints are Spicer Brand.
