The NP231 Extreme Short Shaft Kit is what short-wheelbase Wrangler owners have been dreaming about for decades. Not only does the Extreme Short Shaft Kit improve on strength, but it also increases driveshaft length by up to 7 inches over a stock application.
This kit is also more than 3 inches shorter than a standard Slip Yoke Eliminator Kit and 1.5 inches shorter than an Atlas II. Speedometer readings are transferred through a tone ring and electronic sensor. Details:
