Panhard Bar Drop Bracket

Any special projects involving a decent amount of fab work (bumpers, sliders, roof racks, etc)

I don't know of anyone who's axle stayed centered after a suspension lift. Yours is pretty tall. If you're panhard bar isn't level, your axle should be towards your passenger side.

Back to the original subject, can the frame brace not also mount on the lower bolt hole? You're introducing bending into the bracket that doesn't really need to be there.

I'm not sure I'm following you James. This bracket cups the C shape of the original bracket. It uses the original hole and 1 hole to be drilled as support. Then the panhard bar mounts lower.

OK, well since your post followed mine I assumed it was related to the bar rubbing.

Do you have an adjustable bar? There is no way that your still centered if it is still the stock bar.

I needed an adjustable bar to center mine under the truck. Did not need anything else with stock arms, 1/2 inch longer arms, 8.0 or 14 bolt rear end.

I'm pretty sure he has the Massive kit. Not sure if he realizes that makes a difference.

The diagonal bolt-on gusset-bar that runs from the driver side frame should also relocate down to the new panhard location.

Oh! I could loosen up the bolts and see if it will stretch.

Mine was in fact pulling to the passenger side before the adjustable bar. :cheers:


Erik, I thought you had adjustable control arms, guess not? Why skip that?

Why skip that? Didn't you write up that they were difficult to install? Seems like a common issue with them. I asked in the thread after Regulators recent issue if they have many of these on SS trucks. I havnt seen an answer. But also... MarkMC asked me if I wanted to try out this bracket while I was still cutting corners to get it lifted this year.

After all the experiences I have read about w massive installs, I would not buy them. Not seen one install without a need for modification.

I was thinking about this bracket and Regulators issue and had a idea. What if the bracket looked like below. I am no Mech ENG but would this help both issues with the adjustment arm? Not sure about the shear at the bolt in the middle. Yea quick PP drawing. ;)

James is right that the diagonal support should really go down to the new bracket or the drop bracket could be mounted differently. There's a lot of leverage on those things.

Extending the PHR bracket will help get the roll center down, it'll help with the arc the rear axle travels during bump and droop, but it won't do much of anything for centering the axle. It'll change the handling a bit and it might keep the driveshaft a bit happier.

The only way the axle is going to get centered is with the adj PHR, the only benefit I see to adj control arms is kicking the axle back and for fixing the pinion angle after lifting it.

I use an drop bracket for the PHR on the firebird and it uses two bolts in double shear. The drop bracket goes up the side of the stock bracket high enough that a second bolt hole can be used to fasten the drop bracket to the stock bracket. That's probably a slightly better arrangement than one bolt on the outside of the stock bracket to keep it from pivoting.




I'd be ready to beat my head against the wall if I was Matt. lol
He has an Envoy that has small wheel wells, he has to kick his rear axle back to keep from hitting the doors. To kick the axle back far enough that 35s don't hit the doors he has had to move the axle back far enough that a straight PHR won't reach the stock (passenger/frame side) PHR bracket without hitting the center section of the axle. He either has to bend the PHR, or move the PHR bracket on the passenger/frame side back so it'll fit. Something like Robert posted would probably hold up ok. A couple gussets on top and it would probably need moved back a bit further than that. Maybe a brace on the front side to the frame.

I don't see this bracket helping him in any way.

You have custom length control arms. I'm suggesting he needs those. Which is a side topic to the PHB.

As for the bracket, I'd skip it. There are a few alternative suppliers for adjustable panhard bars. Like Jason stated, it's needed to center that axle. It's not super expensive. Far cheaper than the control arms.

Matt has got to be going bonkers.

And Thank you ErikSS for volunteering the testing and progress reporting of the bracket.
The original idea comes from member Lauron.
He sent me a sample several months ago in hopes that his idea could be introduced
into my product lineup without any royalty's due to his contribution.
For this reason i will be selling them pretty much at cost to offroadtb members in his honor
once the testing and final design is complete.

Thanks to all the members here for your support past and future.
Your dedication to the platform is what motivates my continued strive for new and better products at an affordable cost..

I would like longer/adjustable control arms. However I have stuffed these tires into the wheel wells pretty hard without rubbing anywhere.
I like the James suggestion of moving the diagonal down. As soon as I get too it I will post if it reaches.

Thanks to James for pointing out the cross support problem. I had to loosen the other end of the bar. I had to cut a little off the spare tire bracket to lower the bar. Perhaps if I had lowered the bar before installing the bracket I might not have had to cut.
