I have a 2004 2500 Silverado 4x4 6.0 I like the caltracs and the Smith racecraft assassin bars. I know this will sound petty, but I'm afraid of installing these because of the noise. If they rattle, it'll drive me nuts. Is there any options out there for traction bars that work but don't make noise? I'm putting heavy tie rods and Pittman arm brace in it so if I race it I can do 4x4 launches. I'm just thinking more of when I'm just driving around in 2 wheel drive... It doesn't wheel hop, it just wraps the axle bad. Thanks, Dave.
