I was under my Dister last week and seen that the diagonal link is bending in the middle I do drive it on the street as well as race it several times a year, any suggestions on how to fix it? Or what to do different on the rear suspension to fix it? I fianally got around to taking a picture of the bent diagonal link, it is bent up in the middle and to the right side of the car. The picture amy not show that but that is what it looks lie to me I couldn't find this post so I started another one Please look at this picture and tell me what you think is going on I di add some more information to the other psot on how I adjsuted the diagonal link the last time I put it in, I had to replace it when the ladder bar mounts broke off of the 8 3/4 because of one of the hiem joints in the original link was frozen up and broke off when I treid to adjust it putting it back in the car I had a truck Dana 60 cut down locally and there is around a 1/2 inch toe in on the new set up I'm taking the rear end out now and taking it to Dutchmen in Portland to have that corrected, I'll check the link for straighteness and call 1/4 Max(all thier parts) and ask them the way they want the link installed and adjusted and how to set the ladder bars up in the car as far as straightness

Make one out of chrome moly Cab, that will cure it. poppaj

what size i it? that is probably one of the reasons they tell you not to run one on a street car.

I run one on my street car and never had that problem. Are the joints on the diag free without any binds ? Are the joints on the bars worn ?

...NO more 'doughnuts' in the intersections with the ricers...

if the diagonal is bending, do the brackets on the rear or the front crossmember show any signs of stress ?

I run 1 1/8 CM and put a gusset on the rear ladder
bar bracket(its too far out in space for any side loading)

I made mine from 1" DOM - 1/4" thick wall because I heard of this happening.

steet cars need panhard bars.....if you make the daigonal link better then the ladder bar bracket is next, then the gusset, then........ I have built X braces for street cars.

can you post a pic?

Either its super weak or something is binding

You might try adding on to your diagonal and make it an"X".

Here is a picture of the bent diagonal link, see my first post on top of this post for information update or the other new post I started earlier today on this problem 2nd attempt to attach picture

no pic.

3rd attempt to attach that picture

Could you have hit a pot hole or do you need some curb scrapers cab?

Post hijack alert!!! Cab, What micron screen is in your pre-pump filter? Also, how much higher is your fuel pump than the sump? I'm just seening some potential fuel delivery issues and trying to be constructive, not pointing out any flaws.

Cab...thats an iddy biddy diagonal you have there..

I know there isnt suppose to be that much side load unless you are taking corners pretty hard or something smacked it hard from above like bottoming out a suspension and having the driveshaft hit it..

I would install a beefier one like suggested....

http://en.wikipedia.org/wiki/Buckling

Read up on compressive buckling and slenderness ratio (length to diameter). Think of a pushrod, they fail in the same manner. Go to a bigger diameter (increases the area moment of inertia, I). Changing to 4130 from mild steel won't help since the modulus of elasticity is about the same.
