spindle help

i have belltech 3 inch drop spindles for the 1.25 rotors or at least i hope i do i bought them used (never installed). They say 9903 on them but i cant find that as a belltch part number. I went to install new wheel bearings and the inner bearing doesnt fit the spindle part is thinner than my stock ones. Im gonna call belltech tomorrow but can anyone pass some info my way? im nervous i bought knock off garbage.

Re: spindle help

Belltech will be either #3100 for the Hd 1-1/4" rotors or #3200 for the light duty rotors.
I think someone got you.

That's different.
You may have the correct part.

If the upper balljoint fits,... it's a 73-87 spindle.
Belltech has a 3120 which is a 71-72 spindle.

You're going to have to check the upper ball joint or outer tie rod to know for sure,...

Re: spindle help

HD spindles use the A5 inner bearing.
Light duty spindles use the A6 inner bearing.

Both use the A3 outer bearing.

Re: spindle help

Either way it sounds like you have a different spindle than what is on your truck.

Re: spindle help

Its on the truck all the balljoints are in. I was told it there were for 1.25 rotors which is what i have maybe the problem is they are for the smaller rotors. It doesnt help that i have a terrible italian temper either haha.

Re: spindle help

If they fit the balljoints,... they are 73-87.
If they don't fit the 1.25" rotors,... they are the light duty 1" version.
You can just change the rotor,... but that will also require a caliper change.
