Spohn arms suck.

[KidWgn]

I really thought that I was just having bad luck with mine. They're noisy, clunk a lot, and the rear end has never felt "tight". After finding a group of folks discussing them (on facebook), I ordered some APOC Industries arms (Link here). I've only put around 100 miles on them, but WOW what a night and day difference. The rear end finally feels planted, and all the clunking is gone.

They even include a sheet with measurements for the upper and lower arms, depending on your ride height!

Anyway, all this to say: Spohn's "Del-Sphere" arms suck. Avoid.

Yea I agree that’s why I got their basic arms but I’ve definitely been eyeballing the apoc arms for when I rebuild the Tahoe
Post some pics please!!!

I’m very curious if that curved track bar will clear a bigger aftermarket differential cover I’d love to put a mag hytec on my rig but that’s the main reason I never did

Yessir! I did the track bar, too.

I'll snap some pics tomorrow in the sunlight. Any particular place you want a measurement from?

Mainly the center of the differential cover I reckon? I believe @Doubeleive is the one on here with a mag hytec
I appreciate you getting pics and better yet measurements for us man that’s awesome

I had good luck with the spohn rear arms that were just poly bushings; But they don't offer upper control arms with just poly bushings or anything that has provisions for the rear auto ride. So I was only running the Spohn lower boxed arms and adjustable panhard.

APOC's arms look very nice and everything poly, which IMO is probably better suited for daily driver duty. I've had a conversation with them on their rear upper arms and adding provisions to accommodate the attachment of the rear auto ride sensor links which they can do.

Does your '12 LTZ have the rear auto ride?
Did you get the rear APOC arms with the added rear auto ride sensor link provisions?
If so would like pics of how they accommodate the rear auto ride sensor attachment on their upper arms.

I have the TA performance girdle on mine which is not a big as a mag hytec even with the qa1 bar which has more curve to it than it looks like the apoc has I don't think a mag will fit.
not sure how much clearance it needs

 

[KidWgn]

Pictures as promised. This is with the axle resting at ride height.

Here’s the clearance to the diff cover. View looking up, top of picture is forward. Its between .200 and .250" clearance

@KidWgn I haven't heard about this, what is the problem with the del sphere joints? I've had their panhard bar with those joints on for a few years and I have no complaints. But I remember that if you don't tighten the joints enough they will give you a bad time.

Like I said in the first post: They're noise as hell, clunk a lot, and the rear end has never felt "tight". The trailing arms seemed to be far more of an issue than the track bar. I tightened mine down as tight as I could physically get them, with a 36" ratcheting breaker bar.

The issue I think lies in the Delrin itself. Delrin is stiffer than woodpecker lips, and doesn't lend itself well to a vibration and impact absorbing material. It's a phenomenal heat insulator though!

I had no idea TAP made a cover that fit our trucks! Do you run their original, or low-profile?

as far as I know they only make one for the 8.5" , requires a curved panhard bar the qa1 works but they don't make them anymore also had to hit ace hardware and get different bolts the thread on the ones that are supplied with it are not the same thread.

ya it is the low profile then because that's the only thing you can fit on these.

Interesting. They're friends of my dad's; I'll see if I can get them to send me one so we can see if it works with this bar. Not sure why the hell we'd need a girdle, but it can't hurt lol.

I've been reading up on the 9.5 Esky rear swap, and now I want one.

I put it on there because I have broken probably 5 g80's, put a eaton tru trac in it a couple months ago as well

How in the hell are you breaking them?

And are those 9.5" G80's or the 10 bolt?

I think the 9.5's are AXN instead of G80
