Differential girdle install clearance issues with panhard bar.

[Rocket Man]

I thought I'd start a thread discussing the problem I faced when I wanted to install a girdle in order to provide strength to my differential for high horsepower applications or for those who just want to install an aftermarket diff cover with drain/fill plugs but are having difficulty due to how close the stock or even aftermarket panhard bars are to the differential. QA1 makes a panhard that fits the bill perfectly; it is bent outward to provide clearance for this. I previously had the Spohn adjustable panhard bar but it also didn't provide clearance since it ran in a straight line. After installing the QA1 I had no difficulties although my DJM swaybar did interfere at one corner when the suspension was hanging so I had to clear a small corner of the TA Performance girdle. Otherwise I had about 3/8" clearance all the way across. QA1's website doesn't state anything about their panhard being shaped like this in order to help with clearance issues but if you've ever tried to install a girdle on one of our rigs you know what I ran into. Here's the solution I found; thought I'd share. The RTV will be trimmed once my shoulders heal from the MC accident I was just in so yes it looks ragged right now.

Do you happen to still have the pet number or link to this product on their website? I’m trying to do a b and m diff cover on my 07 and I need at least 5/8 inch more clearance

I don’t see the product listed anymore, maybe it’s not available. I did a search and found that Spohn Performance makes one though. funny thing is, I can only find it on Jegs and not Spohn’s website. It’s part number GMSUV-107R and should provide the clearance you need. Here’s a link.
Edit: bonus is it’s also adjustable so you can also center the rear end left-to-right at your ride height. As you probably know, one issue when lowering these is that the factory panhard bar will make the wheels go off-center to the body as it’s raised or lowered from the stock height. This will allow you to correct that.
