Advance Adapters NP231 Slip Yoke Eliminator Kits

This results in a better driveshaft angle, eliminated driveline vibrations, and a transfer case that's ideal for trail use.

Rugged Ridge Transfer Case Mega Slip Yoke Eliminator Kits
These Rugged Ridge transfer case Mega slip yoke eliminator kits are designed to be used in the same lift applications as the other standard SYE kits. The main advantage to these kits is that they allow for a much longer driveshaft to be used--an additional 3 in. This reduces driveshaft angle, improves bearing and U-joint life, and reduces driveline vibrations. They also have a shorter and stronger main shaft design with improved oiling. They will not work with cable-driven speedometers and are not for use on Rubicon models.

Advance Adapters Shifter Cables
Advance Adapters shifter cables are heavy-duty, robust cable systems designed to replace problematic factory linkages in 4x4 vehicles, especially lifted Jeeps.

They convert mechanical linkages to a cable system, improving durability and shifting smoothness, and are available in universal or vehicle-specific kits for various applications, including those with twin-stick shifters for independent front/rear control.

Jeep Transfer Cases: How to Rebuild
Learn the step-by-step procedures for tearing down, rebuilding, and improving the most popular Jeep transfer cases by using this comprehensive manual, "Jeep Transfer Cases: How to Rebuild," written with the do-it-yourselfer in mind. The transfer case is arguably the heart of any Jeep. It's the key component that splits power to the front and rear axles and ultimately provides the traction that has allowed Jeep to maintain its legendary off-road status for nearly 80 years. Jeep used several different transfer cases in its various vehicle models, many of which have an excellent reputation and remain sought after today. But even the best mechanical components can wear over time and need periodic service to ensure decades of reliable service. While transfer cases may seem complicated on the surface, they can be successfully rebuilt by a competent weekend mechanic with surprisingly few specialized tools. "Jeep Transfer Cases: How to Rebuild" covers rebuilding the most popular and widely used transfer cases found in dozens of Jeep models for decades, including the Dana 18, Dana 20, Dana 300, and the NP231. The entire rebuild process is shown from beginning to end while providing valuable pointers, complete specifications, and a list of the specialized tools that are required. Also included are tips for upgrading these cases for better strength and off-road performance, including deeper low-range gearsets, slip-yoke eliminator (SYE) kits, and much more. Author Trenton McGee has written hundreds of technical articles on virtually every component on 4x4 vehicles for off-road magazines. McGee takes a layman's approach to tackling complex tasks while avoiding complex technical jargon. This book will help you better understand your transfer case and determine if rebuilding your transfer case is for you or your local 4x4 repair shop
