thanks to everyone who posted, im new to this 4wd launching deal lol, but it def sounds like my issue is cv's, ive got a 2-2.5in torsion key lift...right now the bars sit up at 3/4 crank and that cv angle is pretty steep. im sure the warn out idler and pitman aernt helping me much either lol. and does it matter wether the swaybar is connected or not for launching?? mine is out of my truck lol? and tim z do you think ill have problems with the cognito 1" dom tie rods? my truck has had more than one time where a stock one woudlve snapped...ive given those things hell lol but idk if itll give me a prob 4x4 launching, like i said im new to this deal. and justin i can def see that workin good! thanks again man!!

 

Yeah those cognito tie rods are fine bud, You Really NEED to get rid of the torsion key lift, or dont use 4x4 hard.

Put stock keys back in and you'll be fine.

 

thanks alot for the help too tim, its much appreciated. and now i feel like a total idiot, i gave my old stocker keys to my buddy and idk wether he used them or scrapped them...if i cant get em back should i just decrank these all the way? my guess is itd prob be better than leavin it how it is now. also ive watched cognito's videos, with their leveling kit its the 2in keys and UCA's, it looks like their cv's are on a way better angle than mine. would the uca kit help also?

 

Nope.

 

lol wtf was i thinking...thats not gonna drop the cv angle...i think i need to put on a helmet before i make another post lol

 

Theres no dumb questions brother! Thats why we are here.

 

I use limit straps on the front end. Here is the write up that Chase made. Very helpful

If you have any questions about the straps feel free to PM me.

I have leveling keys in mine and they haven't givin me an issue yet. I did decrank them for other reasons, so I'm about 1" higher than stock right now.

 

^^^ I like Chases's limiting straps because they can be preloaded very easily. That's something I wish i could do with mine...

 

Yea they work great. Here is a before and after vid of my straps
