I will definitely follow this! I've been wanting to swap my keys for arms for a while now.

What do you think about my 2" shock extenders? Shuold I just get rid of them? I want to level the front out (if possible), but ride quality is really the most important thing.

What would you do if you were me?.....................and thanks again!

What's your full suspension setup (components, modifications)? I see a lot of rake in your sig pic.

well to get the 3" drop from the arms, my keys are almost completely decranked..I wish I would have just gone with spindles and keys to get me at a 3"...there is like a 3-4" gap from the arms to bumpstops..and there is no "pad" on the arms for the bumpstop to rest on

Something doesnt sound right man. I just installed DJM 3" arms and the ride is just as good as stock. Just looked at my bumpstops which are stock and they are sitting about 1" from hitting the arm. Who installed your drop arms? Almost sounds like the torsion bar isnt indexed with the arm correctly or maybe not indexed to the keys correctly?

The poly daystars are pretty cheap, I'm gonna try to use those first. Might be easier to weld the cups for the pro comp airbumps though. I'm not a very good welder so my homie is gonna help with the hard stuff. Just takes time, budgets suck.

I installed them..maybe i am only about an inch or so from bumpstops, but im still completely decranked..maybe i did set them up wrong? did i put the key on one part turn too much or something? everything went together nicely..one thing is im still on the djm shocks that came with the arms, and tony said he doesnt use those anymore..i really dont want to change shocks AGAIN though lol

Good thread Alex and fellas! Yeah Nick... I am the same way you are in the front. I just cut my whole bumpstop and pad out because they were'nt even closr to touching when under load(bout 3/4 of inch away). And we put torsion back in the same way they came out( we put soapstone marks inseveral spots) Now I'm not all the way de-cranked cause the torsion bar jumped so much. I turned them two full turns up and no more torsion bar bounce over bumps.
I've been a minitrucker all my life so I guess the uncomfortable-ness is something I am used to....Front end could be better I guess.....

I'd double check the distance between bumpstop and the arm. If it really is more than 1-1.5" and you're completely decranked on the keys, I'd start looking to see if the torsion bars are not indexed correctly. Can you describe the ride you're getting now? Is it just stiff, too loose or??? Might just be the shocks. I'd ya ask for fender heights, but with 24's I'm not sure how tall you should be with the arms and completely decranked. I'd be willing to bet that your ride would improve with the keys cranked up a bit though. I'm just trying to help ya figure out why yours seems to ride so bad while everyone else who has the DJM arms says they ride great??? Having such a great looking ride is a shame to not want to drive it because it rides horrible.

So front bumpstops have to be touching front control arm?
I have bumpstops but the slim bumptops like the ones I have in the rear of truck and their no where close to touching should their be bigger bumpstops up front??

I gues I'm screwed because I cut the front stop and bracket clean off! Rides good,but now reading this worries me if it could be better,but I also have the same gap that Nick is talking about.......

When Nick switched to the arms he felt the same as you: http://www.tahoeyukonforum.com/forum/showpost.php?p=337184&postcount=66

A year later some ride quality issues have been exposed.

---

I suspect that what has been said many times before is the truth. These trucks need a bumpstop for the torsion bar to work properly. If you drive the truck for an extended period of time without any bumpstops, the bars lose their spring rate, begin to sag and are unable to control the weight of the truck, giving poor ride quality characteristics.

Interesting theory. I guess that is why sometimes over wavy pavement the Tahoe feels like a boat in the water with the rocking back and forth from side to side. Didn't ever notice that before lowering it with the DJM arms. I attributed that boat-like feeling to not having the rear hardware kit. But then I've only been lowered for a couple weeks now.

I guess I'll need the longer Z71 bumpstops or some lowering keys (or both) to get the bumpstops sitting on the arms again,,,, hmmm.

Energy suspension makes a ton of different sized bump stops ranging from 1" to like 5" tall. I'm sure they'll have one that would work for ya.

They don't have to be Z71 stops but I prefer them. You can get them from the dealership.

I think you might be able to drill a hole in the frame where the mount was, thread a bolt through the top, then thread the bumpstop onto that.

I am curious to see how those arms will work with drop keys. I haven't seen anyone try that. I suspect that would "uncoil" the torsion bar to almost nothing.
