A slip yoke eliminator kit shortens your transfer case, which then necessitates a longer driveshaft. A longer driveshaft means you'll have a flatter drivetrain angle, reducing vibrations and wear on drivetrain parts if your Jeep has an agressive lift installed.
Nonetheless, how do you install a slip yoke eliminator YJ?
However that may be, how do I know if I have a slip yoke eliminator? Yours is a fixed yoke and shorter so theres your SYE aka slip yoke eliminator. The CV style drive shaft you can tell it is one by how it has the to joints right at the fixed yoke on the t-case and it also has that slip joint (where the blue is).
That being so, do I need a Sye with a 3 inch lift?
Registered. SYE is needed for any lift over 2.5" and even that will most likely require a MML. Mine is 3" with a MML and I had to drop my TC about a 1/4" to relieve driveline vibes.
How does slip yoke work?
Slip Yoke and Slip Yoke Eliminator Within many Jeeps, the slip yoke describes an internal splined shaft that's connected to the driveshaft itself using a universal joint. The slip yoke is present to transfer power from your Jeep's transfer case to the driveshaft, sliding in and out of the transfer case.

Phasing is the process of aligning the universal joint yokes on both ends of the drive shaft (or double u-joint)in a parallel fashion. If the joints are not properly phased, they will operate at varying speeds throughout each revolution which can cause second-order vibrations.
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.
