This is what a fully boosted launch can do with my setup.......

I guess the next investment will be tie rod sleeves...

You have all of this and it still broke?

Fabtech 8"
Rancho RSX 9000 Pro w external Res
Bleitskreig Tie Rods
Cognito Idler and Pitman Arm Braces

I run 8" Fabtech and their tie rods, Cognito braces waiting in the garage for the next available weekend and you still had all that movement in your front end? SD centerlink maybe my next purchase. I plan on racing my truck when I get the trans done, and don't want that to happen, and you were in the sand and not on pavement. I wonder if lowering the torsion bars to make the CV angles and tie rods sit level is the answer.

Thats exactly what's installed currently. Look at the toe in......amazing What Im trying to figure out is what exactly is flexing to get that much toe. I think if i can fix that I wont have such a problem with the CV's. I am suspecting the center link currently.

I have seen another buddy of mine also break his CVs with a little more ride height than mine so the height is a factor. His actually broke before the tie rods, which I broke first a few months ago. Unfortunately my 37"s already rub pretty bad as it is so I don't really want to lower the front end at all......

Can someone with a SD center link chime in and speak to their strength, streetability etc?

I pulled out and disconnected the inner cv shaft from the diff and drove it home (5 hours). My tie rods are fine (look at the pic of them in my garage), but there may be something else i blasted in there....i just need to take a better look around. I am also fairly sure that i twisted the centerlink.

I'm no expert but from the pics in your garage it looks like the tie rod will be terrible for tow in. Too much leverage to lift up and rotate the centerlink. I would think your problem lies there. But like I said, I am not an expert by any means.

You have a good point.....not to mention that they are a PITA to align. IT sucks that i have a good $550 in that set. Maybe I will call the bleitskreig guy and see if he can make some straight ones...or I could go with the Cognito ones.

6 megs and only 14 seconds? I thought I was going to have to make popcorn. You know that ford guy is telling stories. Good luck on the rematch.

the CV's broke BECAUSE the centerlink twisted and caused the massive tow in, which caused extreme CV angles. Its not a CV strength problem. If you did not get that massive toe in and centerlink buckling/twisting, the CV's wouldnt have broken. I agree with Tony. Those tie rod sleeves look like they would crank up hard on the centerlink during a launch, thats not what you want! :eek: How many turns are on the torsion bars? Did your lift kit come with aftermarket pitman/idler arm supports?

Hopefully you'll get back up on the road soon...that video was scary! I bet the Ford guy had the last laugh :(

LOL. Actually he's a good freind of mine and he jumps that truck and has broken pretty much every part of it so he understands. He describes his truck as "Big, Old and Cheap!" so basically he recognizes why the dirtymaxes are so great....except for the steering. ;)

dude i think i saw you on I-5 on friday night southbound with a dirtbike in the back of that thing?

nice truck i almost got it a wreck (albeit a slow speed wreck) trying to check out your setup

:ro)

Not sure how many turns are on the bars. It sits pretty much level with the rear so it's not cranked up all the way.

Regarding, I called the Bleitskreig guy who made those rods and he has a straight one that he can hook me up with for a good price, but he made a valid point that regardless of what shape the rod's are the force is applied in a straight line.

That is true, but the bend is giving it more leverage.

That is true, but the bend is giving it more leverage.

Doesn't matter what the bend is, force is applied point to point in a straight line in this scenario. You could use a horse shoe and it would still be applied in a straight line.

Centerlink rotation is definetly causing your problems. fix for that is supposed to be cognito braces.

If you are going to run with the front lifted, you might want to consider a flip over kit to put the tie rod higher at the wheel. This would reduce the angle, and rolling pressure, on the link. The shape of the tie rod has no impact on the loads on the center link. Even straight on, the link bows forward. The SD link helps there by being straight.

And yea, the center link is rolling.

Fingers-It does have the tie rod on top rather than the bottom like non liftred trucks would...

I just threw in a A1 Cardone remanufactured cv and I found some other problems. First off it appears that the crossover contacted the frame rail somewhat hard on both sides. Pretty easy to see the frame rail coating on the red powdercoat. :) That being said I lifted each side individually and found about 2 inches of play in the steering on either side. A closer look reveals slop in everything...the balljoints, the idler arm and the pitman arm. The amazing part is that the truck has 12000 miles roughly on the odometer and that is 95% street miles. Granted, I take the truck out.....and......well things happen in the sand.

So the question is how much slop is acceptable. I am fairly sure that the fabtech balljoints are gonners as they have about 3-4mm of play. The Idler and Pitman on the other hand...well...I can literally watch the crossover ends move down 1/2" or more by pushing the outside front of the wheel in.

Speaking of the Super Diesel Center link...will that work ok on the street? Anyone?

P.S. The location where the video was taken was in Goose Pasture, Florence, Oregon.

I have them installed........and they don't seem to be helping much.

By hand, that is too much roll in the center link.

The ball joint play might be wheel hub bearings instead.

Running very wide tires like I do, I have been beefing mine up my front end to combat some of it's short comings.
