The Rugged Ridge Mega Short slip yoke eliminator (SYE) kit for NP231 transfer cases replaces the slip yoke with a fixed-yoke CV-style assembly for extra-tall suspension lifts. This robust kit is described as the strongest available option for NP231 conversions and requires a CV-equipped driveshaft for installation. The speed sensor is sold separately.
