Convert 6 lug to 8 lug? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is this possible? I am running an 14B FF 8 lug rear already but still have the stock front axle. Trying to find out what would be the cheapest route, converting hubs if possible or finding a 3/4 ton axle.

if you got the correct gears,i have heard that you can get a doner 10 bolt and use the 8 lug rotors and backing plate,on your axle. don`t hold me to that,i personaly haven`t done it.
but if you need gears too,then id just swap out the whole axle..
good luck jamie

I think there is an article about this over on http://www.coloradok5.com It should be in the Tech pages.

Depends on the year of the front axle you have. Most of the time what is required is the hub/rotor assy and the backing plates--you can use the same calipers. The later model 8 lug hubs use the internal locking hubs and the large inner wheel bearing [104949] which requires the later model spindle.
