I Would Buy This Again.

Fit great,looks great,feels great. Only problem is the adjusting bolts rusted up right away. They should have used stainless or better plating. I'll be contacting Hellwig with a picture for replacement.

Great Product

Had a Hellwig 7735 on my previous Sierra and worked great so had to purchase the 7886 for my new Sierra with slight lift. These make a noticeable difference in turns. TruckSpring was great to work with.

I Will Buy Here Again

I ordered this sway bar from another vendor and waited a month for them to tell me they would not have it indefinitely. After canceling that order, I ordered from Michigan Truck Spring. It arrived in 2 days. First Class operation!!

Works Well And Looks Easy To Install.

I am old, therefore I had my mechanic install this with no reported problems! The instructions looked like this would be a fairly easy install-upgrade for a do-it-yourselfer, but my Wife insisted I not do it! It works well and looked much better made than the original smaller "...

I Would Highly Recommend This Product

I put a camper on my truck and it had sooo much body roll, or sway that it was undriveable! I installed my hellwig sway bar in under an hour and the truck and camper drives great!

Fit Perfect On My 2014 Silverado 1500

The rear Hellwig sway bar was a perfect fit for my 2014 Silverado 1500 with no cutting or welding. Big change in the way the truck handles, much tighter and hugs the road better.

Good Quality And Clear Instructions

Added to van to improve stability while towing. Some improvement was noticed. Other than driver side link (through frame rail), installation was very easy.

Big Wig Sway Bar

I purchased a taller, heavier truck camper and the sway bar is a tremendous help. It was easy to install and it arrived exactly on time.
