Heavy-duty driveshafts from J.E. Reel Driveline Specialists are installed at the front and rear of the Liberty. The Nth Degree/AEV long arms are also in view. All J Products replaced the factory NP231 with a Rubicon NVG241OR 4:1 transfer case. This offers John lower gearing options to compensate for the larger-than-stock tires. The transfer case is protected by a custom flat belly skid plate.
