Advance Adapters NP231 Slip Yoke Eliminator Kits
The Jeep NP231 is one of the most popular transfer cases, but it creates an extremely short rear driveshaft. These fixed yoke kits from Advance Adapters add 3 to 4 in. to the rear driveline length on a YJ, and up to 6 in. on a TJ. This results in a better driveshaft angle, eliminated driveline vibrations, and a transfer case that's ideal for trail use.

Advance Adapters NP231 Standalone Transfer Case Shifter Brackets
Retro-fitting a transmission or adding a body lift can cause misalignment of your shifter. Advance Adapters NP231 standalone transfer case shifter brackets resolve this issue, and when used with the factory Jeep skid plate, there is no welding or cutting as with other aftermarket kits. Advanced Adapters brackets eliminate the body type mount found in the Jeep TJ. Designed smarter than the factory shifter, they get a precise fit and smoother shifts.

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.

Rugged Ridge Transfer Case Slip Yoke Eliminator Kits
These transfer case slip yoke eliminator kits from Rugged Ridge are a must if you have installed a 2 in. or taller suspension in your 1987-2006 Jeep Wrangler.

These slip yoke eliminator kits eliminate the need to drop the transfer case in order to avoid the drivetrain vibrations caused by taller suspension lifts. The components in these kits include a reinforced aluminum housing and improved oiling channels, making them the most complete and strongest kits available for your Jeep.

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 provide crisp, reliable engagement for transfer cases (like NP231, NP241, or Atlas) by eliminating binding, hard shifts, and slipping—often with a more direct, cable-actuated feel for better off-road control. 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. The shifter cables are an essential upgrade for serious off-roaders to ensure reliable transfer case operation when factory setups fail under stress.
