brake/spindle question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

im getting ready to order suspension parts and i got a question. right now on my truck i got 1" rotors and im wanting to got to 1 1/4" inch rotors so what is involved with doing this just get spindles that are for 1 1/4" rotors. and i shouldn't have to change the ball joints or anything.

i'm almost positive that the only difference is the size/length of the shaft on the spindle. for the bigger rotors the shaft is 4 1/2"-4 3/8" and the smaller rotors are 4"-4 1/4".

someone correct me if im wrong. everything else including ball joints is the same.

you'll need larger wheel bearings, calipers, and different brake hose

You will need everything that is mounted to the spindle, including bearings, rotor, and caliper.

Are the spindles, bearings and calipers the same on the 3/4 ton (knowing the rotors are different due to the 8 bolts)? Isn't the difference in the control arm side of the ball joint? A lot more scrapped 3/4's around here.
