Either or. The transfer case drop is considered a temporary solution. It stresses motor and transmission mounts. By lifting, you change the driveline angle. To correct the driveline angle, some people change the driveline angle with the transfer case drop.

SYE and driveshaft is the correct way, but more expensive. They'll run you $450 plus labor, but it's something you can do yourself. Transfer case drop is around $40.

For the SYE, you first need to buy one. Every driveshaft has a "slip" so it can change lengths. On the stock driveline, it's in the yoke on the transfer case. This is bad because it can slip out and it's weaker.

With the SYE, you have a fixed yoke, and the slip is in the middle of the driveshaft. Like your front shaft. This is much stronger, and the angles are better.

You first have to install the SYE in the transfer case. Then you have to adjust the axle (I'm cutting the spring perches and welding on new ones but most people just put in wedge shims) to point DIRECTLY at the output shaft of the transfer case.

Once you have everything lined up, you take the measurement for the length of the driveshaft, and order a custom driveshaft. I'm going with Adam's Driveshaft, and already have an Advanced Adapters SYE in the garage.

I would recommend the SYE and CV driveshaft. A transfer case drop is not always effective and that would be a total of 5in of suspension lift
