Well my skyjacker lift made my suspension real stiff , but it doesnt make it really any stronger. Its been said before but the TTB is exactly a beefy axle. It will do for a wheeler that isnt extreme on it. But if you run larger tires , expect to replace ball joints and bearings often. Unless you dont care about it getting a little sloppy. I know theres some stronger ball joints from MOOG I think. That are alot stronger supposedly.
