Spindle Spacers?

[Marcus SC&C]

TwinTurbo,nice pic and nice adj. upper arms! ;) I used Coleman monoball ball joints on a couple projects before the modular tall stud ball joints were available. They`re really convenient to use but I had 2 issues with them. First their total travel is only 36* or a little more than half that of OE ball joints or the modulat ball joints we use now which are both 65*. That limited the travel on cars with more street oriented spring/shock rates. The only other problem is that while they hold up pretty well in the upper location so long as they`re kept clean and lubed (nice job with the boots BTW) they were getting loose in less than 10K miles when used in the lower location (pounding the races out). I`m fairly certain it`s due to the fact that the uppers recieve almost purely radial loads while the lowers take a great deal of axial load where monoballs have much smaller races than a true ball joint.
GUS68,that mod has been used since the 70s. Problem is it`s not quite as simple as drilling holes. The UCA arm pad of a G body is much smaller than the flange of the truck BJs. I did a set several years ago and had to dgrind both the BJ flange and UCA to physically get it in there and the bolts didn`t have much arm to grab once I was done. I would NEVER run them on the street like that. Also the taper of the truck ball joints is wrong. If you ream the spindles to make them fit properly they fall farther into the hole and are no longer taller than stock. The circle track guys just shove it in there and crank the nut down. They`re going to bend the spindle or the BJ or the UCA (or all 3) withing the next few races anyway so it doesn`t really matter to them if it`s "right" or not. ;) Marcus
