I know that the longer upper and lower ball joints help roll center, but how do I know if I need them ? I'm building a new car and don't know if I should put them in now or use stock ??

I didnt have to change much and just used a good eye on changing mine...If you car feels as if it is skating put an upper balljoint for an 84 chevy pickup on the right front its inexpensive and easy to do. You may try cutting the center out of an old one and using the outside as a spacer between your bj and a-arm. That makes it keep its strength. Like I say, worked for me may not for you, and its cheap and easy.

I am a rookie at setups. How do you measure roll-center?

powerglide what kind of chassis do you have, and what control arms and spindles are you using. also what kind of mods are needed to use those ball joints.

Thanks alot Josh K.

I run a 1984 Monte Carlo Chassis. Stock spindles and A-arms. In order to use the chevy pickup lowers (that is what the tall afcos are). the lower ball joint hole needs to be reamed out. I have found that the hand tapered reamer that K-D tool makes works great on the lowers @ 2" taper per foot. The KD# is 2044 mechanics reamer. I welded the lowers into the A-arms last season but this year I'm going to try the sleeves AFCO makes.

I've bought those sleeves from a couple of sources ..... never seemed to work out. I think they may be intended as a spacer to aid in better welding, because all the ones I got were a slip fit, not a press fit.

A few years back, I ended up cutting the balljoint area (hole and 1/2" around) off of some 70 1/2ton lowers and welding them into Camaro lowers.

Later.....I machined up some weld in rings (had a shoulder and looked like the internally threaded weld-in rings made for the K727 scroo-in BJ's .... except, was machined to 1.970" I.D.) that worked out great ...... allowing changes at the track with one of those balljoint (c-clamp lookin) tools.

If you really want to try some of those Afco rings .... private message me your address and I will send you a couple (no charge) still in the package.
