Broken weld on spring perch??? - 07/29/14 05:55 AM
If the weld broke on the right side spring perch broke, would it cause the car to go right at the hit of the throttle??

Depends on where it broke and which side of the car
but if the right side is moving forward then it will
turn right

When that gets repaired,will also reweld the other perch and do the axel tubes and front shock mount tabs.
How do you guys brace the tubes to the perch??

As stated, the perches should have gussets to the middle or tops of the tubes.

Buy some perches from Calvert racing, super beefy and lots of wrap around tube.

2 Per side, 1 front and 1 back of each side of the tube per side.
Someone will have some pics.

For now I would reweld the perches you have and add some gusset plates on the ends similar to the pics of the calvert perches.

I had a buddy draw me up and laser cut a set of these, 360* of weld around the tube.

I just did Dizusters Dana tonight. Added gussets on the ends of the standard Mororso perches that look exactly like the Calvert style. Had The Miller 250 turned way up, welded a inch or so at a time and let it cool between.

you don't need all that, this is the way i do it. just go to home depot and get a piece of flat stock and form it around the tube as it is welded.

All I did was add the flat stock on the ends similar to whats added on the Calvert style and welded it on.

I used to have those same perch'es on my small block charger and they ended up looking like a half moons after about 1000miles LOL. Ended up making some perch'es very similar to the Calvert's

A few years ago I put Caltracs on my car. The first few launches with those crushed the axle tubes and broke the spring perches. After I replaced the rear end housing I used Calverts spring perches. They are very nice...no problems ever since. Here is a pick of my new perches with the old crushed axle tubes that were getting thrown out.

If I was to place a bet, I would agree, however we by the pic have no way to know whether the perch was prepared in the weld area with a 45 degree chamfer, not likely, but possible, and there is no visible chamfer seen in the un welded ends. The weld looks like it was maybe done in place, ie overhead stick, requiring more welding skills and probably apprehension about overheating and warping the housing?
And since the highest stressed area of this area is the weld ends, likely at one end it has the least penetration at weld start up, I unusually turn the corner and go inside the perch at the ends with the weld a bit.
No one has mentioned any warpage issues and rewelding the housing ends, after this now being the second weld up?

Thank you all for the pictures and advise 
Brought the car over to my friends shop.He crawled under the car on my flatbed to see what he needed to do. He showed me how the other perch was twisted. Thankfully I had a set in stock and he picked up some 1/2 inch u-bolts to upgrade the smaller ones I had. I'll bring the car back in the morning.Should take a few hours to box the replacement perches and weld them in properly with some PENETRATION!!

I would have welded the extra straps on at the ends
then up to the tubes.. it has a better leverage
against bending... but at least they look burnt in

Went to the flat part of the perch with the gusset,figured it be stronger than the edge
