Well Hey! (how we say G'Day here ...
) Damo and welcome to the 'Bolt. Truck looks like a keeper fer sure.
The experts will chime in on your exact situation with that disc upgrade, but generally when you see performance stuff like that online and in the catalogs, it's for the half tons not the bigger trucks.
I've been assembling parts to do a disc brake upgrade to a ton and a half truck that Grigg and I are building, and we've had to completely switch out axles. I've gotten a Dana 80 rear axle, and the hubs/calibers and rotors for the fronts, but am still searching for the right axle for the front. We know we are going to have to narrow an axle but the trick is matching the diameter of the king pin holes. If you want disc brakes on that big Bolt, you are going to have to follow the same approach most likely. Grigg will be a good coach for that.
Again, welcome!
John
