Designed specifically for 1987-2006 Jeep Wrangler TJ/YJ and 1984-2001 Cherokee XJ models, this kit requires no drilling and includes all parts needed for installation alongside Rough Country’s extended travel driveshaft. It prevents driveline vibration and rear output shaft breakage, backed by a limited lifetime warranty. ## 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 output shaft from breaking. ## 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 | #33,591 in Automotive ( See Top 100 in Automotive ) #8 in Car Transfer Case Components | | Brand | Rough Country | | Construction | Drilling Required: No | | Customer Reviews | 4.7 4.7 out of 5 stars (185) | | Date First Available | 3 April 2020 | | Exterior | Machined | | Item Weight | 6.8 Kilograms | | 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 | 43.18 x 19.69 x 12.7 cm; 6.8 kg | | 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 ?
