My problem is this. I have a 1992 F 350 4X2 supercab with an aftermarket suspension lift kit. I bought the truck this way, and Have recently replaced the driveshaft center support. However, because of the lift, the OEM replacement is already wearing out due to the angle of the driveshaft. Does anyone know if there is anyplace that makes a support designed for this type of application or some other solution?
You can get a CV added after the carrier bearing..then adjust the pinion to point to it -2*. But have you tried spacing the carrier bearing down?

I haven't tried to space it down yet. Position seems good,,,,,but the angle is off. Then again, if the angle were good, it probably would need to be dropped more, and it isn't something that can be bent to fit. I will probably just have to break down ant take it to a shop that specializes in lifting trucks, and see what they can do.
Excuse my ignorance but does it already have U joints in front and behind the support?

Yes. Front and rear U-Joints,,,,but because of the length of the truck, the driveshaft is split in the middle, and supported by a bracket with a bearing that sits inside a rubber bushing. Trans mount is new, and the U-Joints are in good shape.
Ok, I looked under my FX4 today and noticed that there is a U joint at the end of the rear drive shaft just behind the center support as well as at the differential. The drive shaft in front of the center support only has one u joint and it is at the rear of the tranny.
Perhaps you need to remove the front shaft and have a second U joint installed on it just in front of the center support.

You should not be wearing out your carrier bearing with a lift. The two u-joints on the rear of the drive line should be getting most of the angle. How much of a lift is it?
You could tip your pumpkin upwards and or drop the carrier bearing with spacers. An inch should be more than enough.

Just my $.02 but also make sure that all the u-joints are in good shape, lubed, and freely rotating. I had the u-joint at the carrier bearing rust up in one direction and wore out the bearing quick! Make sure they're the u-joints with the grease fitting so you can keep em lubed.
