Not really meant to be a full DIY (their instructions are fairly easy to follow) but here are a few photos nonetheless of the Hellwig 7907 (2021 only - later years have the threaded hole already present in your frame - so for ‘22 up there’s no drilling required) kit installed. Took me three hours in all, mostly in trying to fish the metal backing plate through to a 1/2” hole I had to drill in the frame on each side.

Nice to see some instructions that clearly show what to do. I saw old posts where people had to be careful about the use of two different diameter rubber bushings when they press those into the short links provided in the kit. Apparently they’ve revised the bracket and that’s no longer the case - all four of the bushings and their steel sleeves are the same (rather beefy) diameter so just press one into each hole using your bench vise. No sweat.

On the right in view. Our 2021’s have the slotted opening in place ready to accept the backing plate the kit provides, no worries there. The fun begins when trying to fish the frame backing plate through - see opening high left in photo and the excess fish wire I left in place for now after folding it up to avoid rattles. On this, the driver’s side, I learned that YOU HAVE TO NOT ONLY SCREW OUT THE BASH PLATE BOLT AS IN THE INSTRUCTIONS BUT INDEED REMOVE IT AND PARTIALLY UNSCREW SEVERAL OTHERS FAR ENOUGH TO LOWER THE BASH PLATE AND GAS TANK MAYBE AN INCH AT MOST TO GAIN SUFFICIENT ACESS TO THE OPENING WHERE YOU ARE TRYING TO FISH THE BACKING PLATE IN..

The passenger side went quickly - there’s no gas tank or bash plate to interfere with getting the backing plate to align with the hole you drilled in order to mount a small 90-degree flange to the frame that accepts the upper bolt of the short links seen in these photos.

A better view of the sway bar in place. You can clearly see the small 90-degree flange that was bolted into the frame in order to accept the upper end of the sway bar link. On the right in view you can see how far back the gas tank and bash plate project - partially obstructing your access the opening in the frame where you need to insert the backing plate. You have to lower that a bit in order to be able to swivel the wire - welded onto the backing plate by Hellwig - nice touch!

VERDICT - a most worthy upgrade if you feel, as I did, that the Bronco felt squirrelly on public roads. It had excessive body roll when taking any corner or even if merely trying to stay in your lane on a twisty country road. Not sure I’ve eliminated any of the nose dive on braking but, all in all, my short-coupled 2-door Bronco just feels more planted and stable on the short drives around town. Would Definitely Recommend!

I did the same, made a dramatic improvement for daily driving and towing. I still have an OE stabilizer sitting here that I bought thinking I had all the mounts for it. Someone should make me an offer.

I installed the Hellwig on my 23 wrangler diesel and you feel it. Right away. Any sway bar upgrade. It’s one of the best upgrades. Now I’m not sure if the 26 raptors have a beefy version or if I can upgrade it. I would/will.
