Rough Trail SYE Kit & Driveshaft Package


For over 45 years, Crown Automotive has been providing the Jeep® industry with outstanding quality replacement parts. That same quality and experience can now be found in our new heavy-duty Slip Yoke Eliminator Kit [sye]. Fits only a 231 Transfer Case.

An Sye Kit is a very Important Upgrade after you have installed a lift kit on some models of Jeeps like YJ's, XJ's, TJ's and ZJ's. The Sye Kit helps to reduce the angles that were created after a lift was installed by shortening the rear part of the transfer case 3" and allowing for better angle.
This kit includes everything to modify your transfer case. This kit does require an extended travel driveshaft, which helps to prevent driveline vibration and the rear ouput shaft from breaking.
