The TeraFlex TJ: NP231 Extreme Short Shaft Kit is what short-wheelbase TJ Wrangler/Unlimited 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 Inch over a stock application.

This kit is also more than 3 Inch shorter than a standard Slip Yoke Eliminator Kit and 1.5 Inch shorter than an ATLAS II.

Speedometer readings are transferred through a tone ring and electronic sensor.
