Designed to enhance off-road durability and performance, this kit prevents driveline vibration and rear output shaft breakage, especially when running lifted suspensions and larger tires. It includes all necessary components for installation and requires Rough Country’s extended travel drive shaft. Backed by a 1-year warranty, it’s a must-have upgrade for serious Jeep enthusiasts. ## 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. Review: Wow perfecto πŸ‘ŒπŸ» de lujo ! Se ve de excelente calidad. Review: The kit was well put together and every part fit as expected. It seems to be a quality kit and the fit and finish is nice. I had no problem installing the kit, the only down side is when it comes to the shifting fork. Depending on the year for you jeep, you will have to cut the longer portion of the shift fork rod so that the case will fit back onto the transfer case. The included instructions did not mention this fact, but if you look on Rough Country's website, it is detailed out. Once cut the case sealed back up and has been functioning fine. Do yourself a favor, and order a rebuild kit while you're in there. It is ease to do and since all the parts are indoor face, rebuild it. ## 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 1 Year Warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B084ZYHPPR | | Best Sellers Rank | 586,435 in Automotive ( See Top 100 in Automotive ) 4,474 in Car Drive & Transmission | | Brand | Rough Country | | Customer Reviews | 4.7 4.7 out of 5 stars (180) | | Date First Available | 3 April 2020 | | Exterior | Machined | | Item Weight | 6.8 kg | | 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 ![NP231 Slip Yoke Eliminator Kit for 87-06 Jeep Wrangler TJ/YJ | 84-01 Cherokee 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 ?

Saved me lots of time and money on shipping a new driveshaft. Result: Removed 90% of driveline vibrations from the car. βœ… The 10% are because its a jeep. No vibes, no drives. ## Frequently Bought Together - Rough Country NP231 Slip Yoke Eliminator Kit for 87-06 Jeep TJ/YJ/XJ - 50-7907 - Rough Country Rear CV Drive Shaft for 1997-2006 Jeep Wrangler TJ | 4-6" - 5075.1 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/238937890-np231-slip-yoke-eliminator-kit-for-87-06-jeep-wrangler](https://www.desertcart.hr/products/238937890-np231-slip-yoke-eliminator-kit-for-87-06-jeep-wrangler) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
