GMC Dually Rear Sway Bar Install

LEAN ON ME:  Adding Hellwig Big Wig rear stabilizer bar improves load control and reduces body lean on heavy-duty pickups

by Bruce W Smith

Heavily loaded pickups and service bodies tend to lean a lot in corners, especially if the load in the bed is a bit top-heavy. Body lean (sway) isn’t a particularly a good thing.

The good news is it’s easy to get under control: add a heavy-duty rear stabilizer bar.

Our 2008 GMC Sierra 3500HD Dually, Big Red, has more than 130,000 miles under its tires. The suspension is stock (sans the 6″ Cognito lift) and it still retains the firm one-ton dually ride.

But we wanted to make sure when 1,800 pounds of service body and equipment are in the bed that our Dually stays stable thorugh corners, dips and over off-camber sections on- and off-road.

So we added both front and  rear Hellwig Big Wig stabilizer bars. The bars are designed specifically for heavy-duty and lifted applications and they are built out of 4140 chromolly steel.

Stabilizer bars are an excellent suspension upgrade for a heavy-duty pickup because performance improves in several ways:

•     Reduces body roll so you benefit from better vehicle control
•     Improves cornering traction for safer driving and cornering capabilities
•     Distributes weight evenly

Installing them is one of the easiest suspension upgrades. The average shop mechanic about 45 minutes to install both front and rear bars. It’s a straight-forward bolt-in upgrade.
