I posted this in the 3rd gen too. I am looking for manufactures of ladder bars like the guys use in sled pulling. My truck has a bad problem of pulling when braking but only sometimes also when it does this the steering wheel is cocked to one side when just normally driving. I replaced the pads and rotors up front and rebuilt the calipers. I think the rearend is moving on me. Just not sure so i was going to try the traction bars and go from there. Kevin
