Its not the locked diffs!
Its not the engine!
its the dogbones!
I ran a Collari 32,Force 32 STS 30...those engines are very torquey.
I have had locked diffs for a long time front ,and rears on both savages.

I have not burned up a drive cup since I changed to those,and I have only broken 2 axle cvds in about 16 gallons of fuel.
You WILL notice a difference in your ride after you put those on.
BTW the 2 that did break the seller replaced no questions asked.
