I have a 2013 gmc w/ a 6.2. I put a hellwig rear bar on a few weeks ago. Everything cleared just fine. Resonator didnt have to come out, had room for everything. I love mine, it helped in every aspect as far as handling. All you need is a hellwig 7800 bar and an hour or so of your time

 

Ok i am sold. I am going to make a call into Hellwig and get the proper part number. Thanks fellas

 

Just look on amazon for a Hellwig 7800 rear sway bar. Good deal and got mine a day & half later and was on the truck a little over an hour after the delivery truck dropped it off. Lol

 

Same experience here. I've had mine for a year and a half now and zero issues.

 

I got my 7800 rear bar from a member on here. I paid something like $150 (included shipping) to my door.

I have to say after putting it in and setting it to the stiffest setting, I roll through curves like no tomorrow.

As for wheel hop, this was resolved when I flipped my rear and added just a little negative pinion angle.

 

Mine works well...I'm quite pleased.

 

Old thread I know, but will this work on a regular cab with a 3.5" lift? Or does the lift even affect its operation?

 

Roll the sway bar brackets up so the sway bar is at the same height as the axle tube centerline. Extend the end links so they're as long as possible (and I suggest adding jam nuts).

I'm on my third truck with the same sway bar (99 GMT800 LM7/4L65e, 09 GMT900 with L76/6L80e, 15 GMTK2EG with L86/8L903) with about 250,000 miles combined and everything is still good except the end links.

 

Cool, thank you!

 

im still day dreaming about these bars lol. Can someone just send me one please
