Well, with an iron 5.7L and a Kenne Bell 2.6L on top of it (that's the thinking thus far), I want to stop as easily as I go. That means Brembo or Wilwood I believe.

I thought 10.5" means FF while 9.5" means SF...do I understand this correctly?

 

i havent tried thsi yet but im thinking the brackets off a TBSS 14bolt will line up with the silverado 14bolt. i havent tried it but im thinking this will work. also some 3/4 ton trucks have the SF 14bolt

 

That is correct to the best of my knowledge. The 2500 and 1500HD have the 9.5" 14 bolt semi floating rear and the 2500HD and 3500 have the 10.5" 14 bolt full floating rear. The problem is all of these axles are 8 lug applications. My '03 has discs on the rear. I am not sure what the newer ones have or when they added discs to the rear.

 

the break down goes like this for 8 lug applications

all have 14 bolt rear covers

the 9.5" had is SF found in 1500HD/2500 with 6L/4L80E
the 10.5" is FF, found on 2500HD's with the 6L/4L80E
the 11.5" is FF, found in 2500HD's/3500 with 8.1L/Duramax/Allison

the older and newer 6 lug applications complicate the mix a little bit

 

Which one is this? It's in an 05 6L 4l80E 2500HD.

 

14bolt FF 10.5", which has the most aftermarket support as its been around a long time

 

Cool! Someone told me a while back that it was a semi-floater, but I thought the flanges on the hubs let the axles slide out

 

You dont trust Baer to slow you down?

 

A 10.5" 14-bolt can be converted to non-floating with custom ends and custom shafts. I originally had mine built for 5-lug wheels, more recently I changed all 4 corners to 6-lug. Discs are available for the conversion - they are the same ones that fit 12-bolt rears that originally had JB6 11" drums. I went with drums.

 

Should I? I've heard horror stories of Baer systems squealing, which would drive me crazy after dropping that much coin.
