four link bushings help please

i cant figure out why my four link bushing keep on busting??this is my second set they work fine but when i gas it they blow ???i told kp what hp and torqe i have can this be a reason why (480 hp, 490 torqe at the rear wheels) ???and i havent even hit the juice off the line yet can i just put a hime joint on insted of the bushings?? i seen some on rail it customs web sight that had rubber in them would that solve my problem???please help here are some pics..

would a wishbone help any??

i dont see the metal sleve in the bushing. do you have one? if your not running one that could be part of the problem.

yea i just didnt have it in the pic sorrry

how long do the bushings last? is it instant?

I think something isnt right, you shouldnt be killing those that fast unless your hitting sides or something

they will last a weil untill i gas it i know its confusing as hell

ill measure it again tommorow for the umptenth time but right now ill try anny thing

will it be the rear end is further front on one side and further to the rear on the other side its not im just asking or its differnt left and right like i said its not i just want to know if that would cause it

thanks for your help guys

that looks like its a chevy kp link set up. are you sure you have the bars in the right way? i know on the 88-98 kit the 4 link bars go in one way, because the bar ends at the rear end have a slight kick to the outside of the vehicle. maybe they are in a bind?

all four bars are the same size upper and lower i called kp up and they are trying to figure it out also???

allright guys i whent to a local race shop and they told me to mesure it out buy putting a plumb bob on the rear frame tube where the spare tire used to be and tye a knot and then put the knot on the top of the tube so the string over hanges the bar on the frame towards the back and they said to put one on both sides so you can measure both sides from the rearend to the string ....they said to do it like this because this factory tube is sqaure off of the frame ....the way i measured befor this was from the rear end to the back of the frame and it measured out to be the saim ....well i just mesured it out the way they said to do it and i was out 5/16 to almost 3/8 yea i feel like a moron but i hope this does it the knew bushing will be in wed. so ill post back and let ya know but thanks for all your help
