Question

Does anyone know or can tell me where, besides the dealer. Where I can find the part number for a GMSPO 5.13 R&P ? Like to compare pricing from GMSPO to the aftermarket. Seeing pricing all over the board.

So far so good on my 14 bolt 5 on 5.5 conversion.

Milling the bosses off the hub backside this week. Then, using a high nickel rod. Will fill the current 8 lug bolt pattern. Face the inside and outside of the flange. Then redrill to the 5 lug pattern. The hub OD needs to turned done a touch also. Thinking about 4.1875 for the 4.250 wheels.

Might water jet a 1/4-3/8 thick ring and super glue :laughing: it to the inside flange face for a little more support. Have to check rotor thickness first.

A lot of machine work but I think it`ll work out pretty well.

I just looked at GM Parts Direct for a 10.5 ring gear, all it showed was a 4.56. They had 5.13 listed but it was for a Dana 70, both prices were outrageous!:eek:

Thanks, that is where I first looked also. And yeah BIG $$$ even at the so called discount :laughing:

Hate to call the dealer but I`ll give them a try. Shits and giggles at least.

I think the 5.13 has long been discontinued. good luck!

Suspect you are correct. Dealer could not find it.

Gotta wonder about a Motive gear set for 200 bucks vs. the others at 350.

Both seem to be of 8620 steel. Why the big price difference ??
