Designed for 1997 and newer Jeep YJ, TJ, and XJ models, this all-inclusive kit prevents vibration and rear output shaft failure, making it essential for lifted Jeeps with larger tires. Installation requires Rough Country’s extended travel driveshaft and is backed by a limited lifetime warranty, ensuring your rig stays trail-ready and reliable. ## Description Jeep model NP231 transfer cases have one glaring weak point. They use a slip yoke on the rear output shaft of the transfer case instead of having a fixed yoke and a drive shaft with slip splines. This design works fine on the street but once you have lifted your Jeep and installed bigger tires on it, the stress on the slip yoke or rear output shaft is often too much. This Heavy Duty Slip Yoke eliminator kit includes everything to modify your transfer case, this kit does require our extended travel drive shaft, which helps to prevent driveline vibration and the rear ouput shaft from breaking.This kit converts transfer case from slip yoke to a fixed yoke for improved off-road durability and performance. Fitment Notes: For use with NP231 model transfer cases ONLY. Does NOT work with factory driveshafts. An Aftermarket CV driveshaft is required for use. Designed with the most current design shaft found in the New Process Gear NP231. This current design shaft was introduced in 1997. Jeep vehicles using the early NP231 can still use our kit, providing that the needle bearings are removed from the stock drive sprockets. ## Features - Wrangler/Cherokee NP231 Transfer Cases have One Glaring Weak Point. | Slip Yoke on the Rear Output Shaft. - Converts Transfer Case from Slip Yoke to a Fixed Yoke | Improved Off-Road Durability and Performance. - Designed for NP231 Transfer Case on the YJ, TJ, and XJ. after 1996. | Earlier models must remove the Needle Bearings from the stock drive sprockets. - Provides everything to modify your transfer case | Requires RC Extended Travel Drive Shaft | Prevents Driveline Vibration / Rear Output Shaft from Breaking. - Backed by Rough Country's Limited Lifetime Replacement Warranty. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B084ZYHPPR | | Best Sellers Rank | #111,840 in Automotive ( See Top 100 in Automotive ) #30 in Automotive Replacement Transfer Case Components | | Brand | Rough Country | | Construction | Drilling Required: No | | Customer Reviews | 4.6 4.6 out of 5 stars (194) | | Date First Available | April 3, 2020 | | Exterior | Machined | | Item Weight | 15 pounds | | Item model number | 50-7907 | | Manufacturer | Rough Country | | Manufacturer Part Number | 50-7907 | | Model | Rough Country NP231 Slip Yoke Eliminator Kit for 87-06 Jeep Wrangler TJ/YJ | 84-01 Cherokee XJ - 50-7907 | | Position | Driveline, Rear | | Product Dimensions | 17 x 7.75 x 5 inches | | Special Features | Works with NP231 Transfer Cases ONLY. | ## Images ![Rough Country NP231 Slip Yoke Eliminator Kit for 87-06 Jeep TJ/YJ/XJ - 50-7907 - Image 1](https://m.media-amazon.com/images/I/71HdGt1SOQL.jpg) ## Questions & Answers **Q: Can you recommend a driveshaft ?** A: Depending on your configuration, RC likely has the driveshaft you need as well! **Q: Do i need a new drivshaft?** A: Yes, you would need a new CV Driveshaft. **Q: Does it come with the speed gear ?
