Radius arm question
Not sure where to post this.......
As some of you know from my build thread, I have radius arms and coilovers on my Blazer. Radius arms will bind in an articulating situation. Since I have these arms built, can I just "cut in" a small shock on the upper arm like my paint pic below? The shock could act like a sway control to some extent. Any thoughts? |

Re: Radius arm question
I would scrap the upper arm, move the top mount and |\/| to the diff/axel truss if you are trying to articulate... Is this a daily or ?

Re: Radius arm question
I don't think you would want a shock in there with coils.

Re: Radius arm question
No you can't do that. You need to have more solid control of the rotation of the differential. I have to agree with Eturnit3, if you want more flex you'll have to go with either a 3 or 4 link. You did some nice fab work there....

Re: Radius arm question
I dont want or have the room for a 3/4 link in the front. I only want the shock on one arm, the other would stay as a radius arm. Looking at lots of rigs on Pirate4x4, they have a radius arm on one side and a single tube on the other. They call it a "Wristed Arm".My thoughts are the same idea, just with a shock to slow the "flex" some. The one radius arm would control the rotation of the diff.

Re: Radius arm question
It appears that your current arms are essentially "ladder bars". The two rear mounting points are "fixed" and even tied together vertically. Why would you even think that you could introduce the possibility of movement in the length of the upper link? This would put all of the force at one tiny point. (Arrow)
This is why the monster trucks have such long arms, and mount them so low. Ladder bars (radius arms) don't deal well with longer suspension travel....especially in the front. You will have quite a bit of caster change through-out the travel. A four-link will give you the travel w/o binding. What are you using to keep the axle centered?

Re: Radius arm question
Good point, did not even think about that!! I feel dumb now
 That tube would have to come out in order for the arms to be separate.I have a track bar for the centering. |
