NBS brake swap on 2WD GMT400 almost complete

[Chris Rogers]

14-16 may be aluminum, the 07-13 is cast iron, I'll run some numbers tomorrow and look at some trucks on the lot to double check.

if you can please. I have the numbers for the later ones based on a 2015 Z71. want to confirm.

The 22760658 and 59 are cast iron, the 22842314 and 15 are aluminum. I'm glad I posted this info before I got through, I believe i'm gonna try these aluminum ones to see how they fit compared to the ones im using.

 

[Chris Rogers]

Thank you sir. I will see which ones surface. ( I'm in oz truck is in Texarkana.)

There was mention of someone on this forum using the aluminun ones but they couldn't get a part number.
For me it's about weight distribution. Remove a bit off the front and move it elsewhere..

I'm going to order these aluminum knuckles and see how they compare, looking in the catalog, all the bracketry and components are different, so I may need to revise some of my part numbers before I post them for everyone else.

 

[Chris Rogers]

Noted. I am interested in seeing what's different. I have a 16" rotor and 6 pot willwoods in mind for mine. I'm told that these fit 99-15 trucks with no mention of the aluminum knuckle.

Once I have these aluminum ones in hand I will measure them to see if there is any tolerances that would make a difference as far as brake selection.

My research on this shows that there is a Dodge 1500 front bearing that bolts into these spindles if you want to keep the 5-bolt pattern. Its a 5X5.5 but a lot easier to re-drill for 5X5 than the 6-bolt bearing. The spacing and everything is identical, so rotor spacing wont be a problem.

Because of the slight difference in spindle height, I am going to ream the bottom B/J hole and put the ball joint in from the bottom-this will automatically give me 2-3" of drop.

sort of like this;
