Alrighty...im going to give my review of each to help people make a desicion on which to go with.
I have had the cognito braces on both of my duramax's so far and have zero complaints. Last one was lifted on 35's so the all season brace was not an option. Cognito stuff worked fine.
My current duramax got the cognito stuff the day i bought the truck and have had it on for 2 years. No problems and no complaints. Been to the drag strip countless times and they have worked nice. Well i decided i wanted to try an all season brace and i just so happen to get a hold of a brand new one for a great price. It showed up today and also got it installed. Install is pretty easy on both cognito and all season...All season being easier.
just went out for a drive with the all season brace and also have zero complaints.
I heard some people say that the nylon part sits a hair off the diff. Mine is in constant contact with it unless the wheel is turned. You can see the shavings here...This is from a 10 mile drive. It physically pushed my diff back about 3mm when i tightened the bolts for the brace. Guess once it wears in it will be perfect.
Here you can see the angle it's already worn into the nylon and how it's touching the diff. I even ground the edge of the diff nice and smooth. I'm going to hold onto my congito stuff for a bit just incase.
So I guess I can sum this up by saying flip a coin and go with whatever one you want. Both seem the exact same to me while 4wd launching.
