Reinforced trailing arms Options

[echocanyons]

What is the purpose of doing this? I have seen it on a couple of 6's but the only thing I can think of that it does is restricts lateral movement.

If this is a uselful suspension upgrade is it basically fab your own or is somebody producing these?

Thanks Phil for backing me up.

Worthless.

Here is how I look at it:

If I hit a curb and the arm is boxed... guess where all the load goes ?? The inside ear (that is weak anyway). I can replace bent control arms for about 50$ a side. I cant replace/fix that ear for anything under 800$.

So.. I will try and bend control arms all day before I EVER install the control arm stiff kit. All it does is ad weight to a unsprung item.

I wish my friend who did the structural analysis on a 914 control arm had time for this BBS. He is engineer in Texas (Al Swanson for those of you who know him) He spent a lot of "real" engineering time on the 914 control arm to discover the same thing I had been saying for 15 years (they are plenty strong and the box kit does nothing for how they are actually weak).
