Dually

[BULIT]

Question about spindles , will truck dually rotors fit on a 72 3/4 ton suburban spindle and are the calipers/brakes the same for both vehicles as near as i can tell the seals and inner bearings appear to be the same on both but the outer bearings seem to be different not sure about spindle length , so basically what to i need to run dually rotors on a suburban


Thanks

It'll be a bolt on and go since your 'Burb is already set up for disc brakes. The outer bearings are recessed into the hub, that's about the only difference.

I can`t find part numbers for the dually rotors we tried raybestos , bendix , wagner and chevy, but chevy gave a part number 338301 but said it was discontinued none of the above vendors could cross it SO where can i get these rotors or part numbers and manufacturers


Thanks

Anyone know if dually front rotors from a 73 up chevy or maybe from a dodge or ford with 6.5 bolt circle 9/16 studs fit on a 72 3/4 ton suburban spindle or what possible spindles/swap would i need to swap out to make it dually in front apparently 72 dually rotors are no longer available

Thanks for any help on this

Don't know if you got an answer to this but when I swapped mine over to 1 ton I used the following.
Use your stock a-arms from the 3/4 ton. The bottom ball joint is the same for 3/4 ton and 1 ton 65-87. Change the upper to the 73 and up ball joint and 73-87 1 ton spindles will bolt up. Use 73-87 3/4 ton inner and outer tie rods and sleeves with the stock 72 3/4 ton center link and idler/pitman arms and you should be in business. If ya already got it done this is redundant! Hope this helps.

I would aslo recommend what Crew said because down the road the 73-up parts will be easier to find and cheaper
