I'm going to stray from the pack here. I personally think you're pouring money down the drain investing in an SYE if you do not need it. If you have no vibes and the slip yoke isn't hanging out when you articulate the rear, what's the point? When you go higher then get your accurate measurements for the length of driveshaft you need so that you will have a shaft that is custom for that lift. If you have money to burn spend it on something else like rails or recovery equipment or something else. Or paypal it to me. :laugh3:
