Hellwig "Big Wig" Sway Bars are designed for trucks that haul & tow on a frequent basis. These massive 1 5/16" solid steel sway bars reduce body roll & increase stability by 20% over standard sway bars. They transfer the pressure on the outboard wheels and apply opposite pressure on the inboard wheels. Weight is more evenly distributed to all four wheels helping your vehicle stay more level with the road. Designed to be simple to install with simple hand tools.

Looks nice.
I was hoping to gain better control of my fifth wheel camper with this installed. 2 problems tho. 1st. 5" exhaust won't allow for mounting. 2nd. 2" suspension lift, means brackets and mounts are not long enough. I going to try and make longer mounts. Exhaust I don't want to cut into box of truck. Plus need clearance in box for turning with camper.
