I have a 2002 Bob pierce chassis and need a few questions answered. Does anyone know the part # for the upper ball joint? Also need to know if the spindles are anything special or just a stock metric and are they reamed for the bigger ball joints?

upper ball joint part # 20032-1 afco
spindles are just metric spindles off of like a 80 monte carlo you dont have to ream the top but you do need to run a 5/8 drill bit through the bottom, do not ream the bottom

What is the bottom ball joint? Is the idler arm the stock metric or? I just bought a 2002 pierce and need to get all the spares in place as my old car was a jet with the big metric stub. I will have to say this is the best car I have ever driven and has ungoddly forward bite and it seems to really work great in the center of the corner.

Lower is a 20038-1 afco and everything else is the stock metric except the tierods there the camaro inners and Nova Lowers.
And yes they are very nice cars. I like them a lot. The tech. help could be a little better, But there isnt many times you need to talk to him with the info he gives you.

The part # for the lower ball joint from moog is K6117, upper is K6136. the tie rod end is 11\16s at the end. takes a special tube that is 5\8s right outer, 11\16s left hand inner. It drops the tie rod down some so it won't hit the frame. TRW # is ES443L.
Guess I spent too much time at Pierce seminars!

The box I have is off a 86 regal so that should be the same but it puts the tie rod in to the cross member. The old pitman arm looks like it has been shortened

Im not sure what you have going there, But I never shortened on up, I know it brings the tie rods close to the frame

I wonder if a frame horn has been relaced and not cut long enough.

If you are using the 605 box the pitman arm should be 6 1/4" center to center, the one that will fit the 605 box is off a 64-66 chevelle with no power steering. On the idler arm its 6 3/8" Hope this helps.

We moved our LR lower bar UP one whole from level or where Bob wants the car initially set-up. It gave it more bite but also made it loose steer a bunch.
We had alot of trouble with the panhard angle that Bod told us to put in the car. It worked great until the track got rough and then it acted like a pogo stick and the car became a handfull.We tried moving the panhard up one whole on the pinion and we would loose side bite. We were going to try a J-bar but ended up selling the car before we got a chance to try it.If the track was smooth the car was a rocket with Bobs initial set-up.

His new panhard bar on the right helped that a lot. We had the same problem last year, Bob told me him self, When the track is rough his cars are like riding a bucking bronco

the brace on the lift bar so the panhard bar will fit through, you have to move it forward a little or it hits the heim

Found the problem the junk yard gave me the wrong box and the pitman arm was an inch longer than the metric.

If the tracks are rough all the time, you can go to a z link on both sides. This can help. I also think a little stiffer rf & rr shock helps. gl ltr

No, what he's wanting to accomplish is keeping the car off the bars and keeping it on a spring so that the rough track is obsorbed better by the springs rather than the suspention making the car really a rough ride.

i have an 05 bp car and it was 4-z on a rough track and it was a real handful..has anyone tried the z-z on a rough track and had good luck with it? does it take away forward bite? i sometimes run a rough really,really dry slick track, and with the bars setup in the dry-slick holes it's a real rocket when its smooth, but what do you think it will do with a z-z set-up on it?? thanx for your help...

I wouldnt run a z link on the left side, I would take bar angle out of the car on the lr, raise panhard bar on pinion, Go up on shock stuff like that.

z-links on both sides give the impression of a leaf spring car. They work great on a really rough track. Don't change anything else but the top bar.

Around here double swing arm / z-link cars are the hot ticket. Several of the top runners are running them set up this way.

One of the biggest advantages is the cars drive striaght and hard up off the corner.

Changed pullbar spring, any suggestions on how to set pinion angle? I run a pullbar and a lift arm, Lift arm has brake chain only. Pinion angle is at 7* with the chain tight, should I leave the chain on and set the pullbar in or should I unhook the chain and set the pinion angle with the pullbar and then hook the chain up?

disconnect the pullbar on the rearend side, leave the chain on and set the pinion angle with the brake bar, do all scaling and set up with the pullbar disconnected from the rearend. After all set-up is done just adjust the pullbar length so that the bolt slides through the rearend braket and the pullbar with out pushing down or lifting up on the car.

last year we always bottom it out too but we ran a lot of bar angle.
this year we dont run a hole lot of angle in the 4-bar our upper link never goes in the top hole. Only the bottom or middle hole.

I know some guys that moved shock mounts so they can get more travel on the rear and they bottom the shock out real bad
but to answer your question last year we did and this year we dont

run 94 series shock. I've learned that if I ease out of the gas instead of abruptly letting out of it, it doesn't bottom out. Th reason I bottom out is because of the bar angle I run, allows it to slam down when I let off the gas.

yes afco bp shocks are good and u can get any valving u want.
our rf maybe bottoms out just once and then u can look at where the dust dirt is and this will tell u where the shock is running most of the time.

right,
Now what do you mean you can get any valving you want.
with the BP shocks he has a slick track set up and a wet track set up.
thats it. They dont even have the valving # on the shock, It just has a BP-1 BP-2 and so on.
when you need a new one or something you call him and ask for a BP-3
a dyno sheet comes with them and tells you the rating of the shock at different velocities.
but it is not like a 94 or 93-5 or something like that!
all I know is they work!!!!
