We knew we were going to lose some rear driveshaft length and were going to need to modify both driveshafts with the swap, but we were really surprised when we compared the before and after measurements. According to our notes, we lost 5 1/8 inches of rear ’shaft length and gained the same amount in the front. This could be a deal-killer for some people, as our final length of 20 1/4 inches doesn’t leave a whole lot of length for a taller Jeep. We called the experts at JE Reel with our measurements, and they recommended going with new ’shafts, as well as converting the rear to a CV joint at the transfer case. The company’s high-quality driveshafts arrived a couple days later, were exactly as ordered, and bolted right in. Though not really needed now, the CV will be important if and when we decide to lift the Jeep higher than its current 2 1/2 inches.
