Djm lower. Arm question

[Num12005]

I just lowered my 05 Tahoe with Djm 3" lower control arms.Question is ,what jounce stops can I use?Any help would be great,I've searched but can't find my answer.

Ask Tony @NORCAL SS since he sells those arms. He will know. If I remember they don't use jounce stops.

I asked him and he said don't run them.I thought these truck were designed to be ran with the jounce stoppers??After the install it drives weird,road walks..

I remember thinking the same thing, that it wouldn't ride right without jounce stops because from everything that I know, they're an important part of the front suspension. I would contact DJM and talk to them. Maybe there's a way to retrofit jounce stops or they might have an explanation as to how the arms work without them. The answer of " just leave them out" wouldn't work for me. I'm interested to see what the resolution is; keep us posted.

I sure will.I am the same way,but he seems to know his stuff.I'm gonna call djm and ill post what they say.

I called djm and talked to "mike",dude isnt the best tech ive ever talked too,lol.He says oh yea it needs to have the jounce stops.Then i asked him why and he had no good answer at all.I told him how it was driving and he says,"let some air out of the tires",lmao..So I looked at yhe a arms a little closer and the factory (one that I had) doesnt touch the control arm at all..Guess I'm just gonna run it without?!

 

[Rocket Man]

So he said it needs jounce stops but there's no place for them?

No,he said do not use them.But I was asking if the design and how they use the jounce stops as an essential part is necessary with the djm lowers

Do these arms require special alignment settings? It seems to me they'd alter the suspension geometries enough to do so. Maybe more positive caster?

@blurred is having alignment issues with his as we speak. http://www.tahoeyukonforum.com/threads/djm-lca-uca-alignment-issues.96507/#post-1152828

Sounds like spindles and coilovers would be a better way to go. Glad to see this...doesn't make sense for the djm arms to work without the jounce stops..will spindles clear 24s lol..

I'm running 26's with 2" drop spindles and it rides and drives excellent. When I replaced my wasted jounce stops it rode even better than before. From my experience I believe they are important and I don't understand how DJM just says to throw them out but offer no explanation as to what is replacing their function.

There was a recent post of somebody grinding them to touch even more. Smart.... Do it.

Djm has a stop on the lower arm for them.

 

[Num12005]

My djm lowers do not have a spot for the jounce stops to hit.There is a piece of strap that is for bracing but that's it .I called Tony again with these questions and he says factory upper control arms are ok to use,but man just by looking ,the balljoint angle is BAD.My truck drives like shit after the 3" lowers..Pulls both ways and wonders pretty bad.Alignment guy said it aligned no problem.I can't find ANYWHERE that talks about running the jounce stops with these lca's..Feels like something is loose in the front end ,I think its a combo of uca angles and no jounce stops.I sure wish I'd have done spindles!!

 

[Num12005]

I have a better term to explain my issues,bumpsteer..Bumpsteer is horrible with these djm lowers have gave me a whole set driveability issues.Sure wish I knew a fix for the bumpsteer and raodwalking..Sad to say,I'm thinking about taking it ALL off..

I will have the DJM upper control arms for sale once my new uppers come in. They would have worked out well for me if I didn't go lower than the 3" that it gives.

Also, that "bracing" you mention (I call it the strike plate)... Is that on the front mounting point for the LCA? If not, then why would they brace just the rear?

I have the djm lowers and run jounce stop there part of the suspension. The stop should attach on the truck side and control arm has a plate to make contact. You can run whatever stop you want depends how you want the ride.....the arms are design not to change the geometry I believe

I've looked at DJM's website and there is no pad on the lower arms for the jounce stops to hit in the pictures. I've also heard that DJM says to not use jounce stops because they're not needed. Maybe you both can enlighten us by showing pictures of this area. Maybe they have 2 different versions?
