Can anyone tell me what I've got here. My pop said he bought these as
'99 - 06 Belltech -2 spindles... but unless they're super old, they are not. not sure what they are.
What I am sure of is that both ball joints must be flipped, and as such there is barely 1/4" of threads engaged on the lower ball joint.

Stock on left, drop on right


These are the only markings on the spindles



on my '00, if I just flip the lower bolt in ball joint and put it back in the same place, I get 3" drop. If I use a spacer and bolt the ball joint to the bottom of the LCA, I get 2" drop

 

Looks like you have another set of factory spindles

 

no, they are clearly designed for a drop. the bores for the ball joints are tapered such that they have to be flipped.










I found out that these are discontinued belltechs. I haven't found out why they changed the design though.

 

Belltech spindles typically have their logo and/or part number stamped on it. But yes it does sound like the 2505 spindle. The balljoints can only be purchased from rareparts.com

 

What's the deal with the ball joints? do they have a longer shank on them, or are they offset?
When I put the new ball joint in the stock location, it appeared to have about a 3" drop, but if I used a spacer and mounted it to the bottom of the LCA, it was closer to 2"

 

Here are the install instructions

I just acquired a set of these if anyone wants them.

 

i'm pretty sure I gave mine away.

i checked on alternate lower balljoints & they didn't have any longer shank than the one I had.

with the stock & later model drop spindles, the ball joint is above the spindle, so the spindle bears on the balljoint, pressing it into the taper.

With this flipped setup, all of the weight is trying to pull the joint out of the taper & the only thing holding it in is that castle nut with insufficient threads.
i couldn't bring myself to drive it around like that, so I just bought the later model belltechs.
