What else can they do other thane keep the front end straight? any performance improvement, if so How?

No performance improvement, except the piece of mind that allows you to launch harder in 4x4, which equates to a faster e.t.

I'd say there is a small gain, watch and listen to the pigeon toed trucks.
The tire squeal has to be robbing some hp/et.
Notice how the jerks and bounces the front end when they are toed in?
This is unloading the front tires too.

I'm with dmax tim on that. I made the test...

Just keeping the front end straight with sleeves AND a strap on the centerlink gained me .15 on the 1/8. I have never been able to go in the 7s with my "loose" front end setup and believe me I tried...

That was with my 265s However, doing the same thing on the 305s with offset mags wasn't enough and I was still launching with alot off toe-in.

did your 60's change and what did your MPH do? Thanks. I figured along the lines of tim but didnt think it would net you that much.....

also did you have your bars all the way down before?

I didn't have any time slips a that event. It was a big rig drag competition and I was doing exhibition runs between programs. I only had the ETs. There was NO glue on the asphalt lauchpad. I assume I could do a little better (another .15) on a cement glued lauchpad.

My best ET in similar conditions was 8.17 sec. and I did around 7.99 sec. a few times that afternoon. I could really "feel" the truck going straith on launches. I used to launch at 10-12 psi without the sleeves but now I do 16-18 psi, I guess that helps alot too.

Before I was battling the steering wheel real bad for the firts 2 seconds of the run. I even have my little launch anecdote... My nitrous is on a hand trigger and I was racing that car that I used to beat but barely. I could feel something was wrong as he was getting in front. I was pressing as hard as I could only to realise that I ripped off the trigger from the wires comming out the dash because of the violence of the launch... I added 2' more to the trigger line "just in case" :grd:

As for the Tbars; I used to run around with them pretty low but this time I went lower than usual, the negative camber was really visible and the front shafts ad a negative angle (going upward to the wheels) when they used to be pretty straith.

Need to go to a real 1/4 dragstrip to see some real improvement... are you listening Mr. duramaxdiesel? :ro)

I didn't realize the sleeves stopped the toe in.

I thought a new SD centerlink was the answer for that.

I think if you bend em at all they dont bend back ussually. I may strap my center link next time for grins though to see what that does. Normally my truck leaves straight unless I break traction

The biggest gain is relized when you try and go home..

By reading my firts post I tald about the combined effect of sleeves AND straping the front end.

I don't think the sleeves stops the toe-in they "may" help a little but mostly they let us launch at higher psi wich in turn lead to better performances wich is the topic of the thread.

SD's centerlink seems to be very effective at stopping the toe-in. I use the poor's man method wich is to strap the senterlink to the crossmember for the time being.
