I wanted to get some feedback on my plan, I want to get a 1" uniball and to install it in my upper djm arms i want to drill and then ream out the current balljoint cup so i can drop in the uniball cup then i will tig weld it on the top and bottom edge to tie it to the existing cup and i will also do some 1/2" rosette welds front and back.

Does this sound like a good idea? Does anyone have any experience with these and can you recomend any hardware or installation tips, what ever.

I'm not quite folowing what you are asking, but if you want to replace the upper ball joint with a uni-ball, go ahead. A 1" uniball is absolutey overkill! TrophyTrucks do 160+ mph across the desert with 1" upper uni-balls, you can easily use a 3/4" or 7/8" uniball and get away with it. The 3/4" uniball will offer the most angle (32 deg) with a 1/2" bolt.

If you can, post some pics of what it is you are trying to accomplish.

this is what my current djm upper arm looks like. The reason im gonna drill out the balljoint cup is to keep everything concentric with out using a jig to locate everything. My buddy said he was rocking the 1" uniball with the belltech spindles but i suppose i could go 3/4 and then if the hole in the spindle is already too big because of the taper i can alwayys ream it and press in a bushing of some sort to bring it back to the dimension i need. Can ya picture what im saying? I just want it beefy enough to handle the stresses of the rams upper balljoint angle as well as not bind up on me. Plus its cheaper then a damn balljoint for a ram.

Yeah, that makes sence. There is no reason that it wouldn't work.

"if the hole in the spindle is already too big because of the taper i can alwayys ream it and press in a bushing of some sort to bring it back to the dimension i need"

Exactly...

Hey Max if im reaming the spindle for a bushing do you think i should do a slight interference fit and then heat the spindle and press the bushing in or will that cause too much stress once it cools?
