Spindle/Rotor issue
 

Hello everyone. New poster here. Been searching on here for a while now.

But i have a few questions. My mom bought a 1983 C10 a few months ago. And she gave up on working on it. I have taken over the project recently. I started to take rebuild the complete suspension.

Lowering the truck with a 2 1/2 front and 4 rear. She bought the drop kit from LMC. Not a big fan of lmc but not to bad for smaller things.

My issue is the new spindles came in with only a 4 inch axle shaft. The old spindles have a casting of K10. Makes me thing the truck might be a K10. The specs on the old Spindles are 41/2 inch axle shaft. 1 3/8 inch inner bearing size. Those are my 2 issues. The new spindles are 4 inch axle shaft, and only 1 1/4 inch inner bearing size. Rotors are 1 1/4 wide rotors and 11 3/4 inch length rotors. Outer bearing fits on both just fine tho.

What makes a C10 and a K10?
Changing rotors solve the problem? To a 1 1/4 inch inner bearing size? And a smaller rotor to fit the 4inch axle shaft? If thats the fix? What rotor is the one to use? Part # or link appreciated.

Thank You for ur help. Will keep in touch with the progress.

You have HD rotors and LD spindles if I'm reading your info correctly.

Thanks for the fast reply.

Even looking at local parts stores. Specs online. I dont see a rotor to fit a 4 inch spindle shaft. Stock rotors measure 4 1/2 deep. Theres a different year/model that will work with these drop spindles?

What brand spindle did they send you?

You must have ordered drop spindles for 1in rotors. You need drop spindles for 1 1/4in rotors or convert to 1in rotors, inner bearing, and calipers.
