Jeep Wrangler Slip Yoke Eliminator Kit - Rugged Ridge - NP231 - `88-`06

Jeep Wrangler Slip Yoke Eliminator Kit - Rugged Ridge - NP231 - 88-06. This heavy-duty kit converts your NP231 transfer case from a slip yoke to a fixed yoke for dependable performance on and off the trail.

Designed for Wranglers that work hard, this SYE shortens the output shaft by approximately 5 inches to allow a longer rear driveshaft and helps improve driveline geometry after suspension changes. The fixed-yoke setup increases durability versus worn factory slip designs and supports smoother power delivery in rugged conditions. Rugged Ridge steel construction and a limited 5-year warranty offer confidence for daily driving and weekend wheeling.
