I bought a kit for my '97 TJ Custom Rubicon Conversion and installed it or at least tried to install it at Jeeperformance. One of the axles bent at the attachment point of the gimbal; something the store has never seen before. I returned them and bought Revolution Chrome Mo Trucks; They come with a ten year guarantee and there have been no installation issues. The mechanic working on the modifications to my Jeep wondered if those were real Yukon axles or a fake. I hope I just got a defective set.
