The
Performance Online spindle kit seems like it only includes spindles.
The
Performance Online complete front kit seems to have the same stuff as the CPP and is a bit cheaper. Add $20 if you want 6 lug.
The
CPP kit includes the same components and make a complete package. It's slightly more expensive.
Both kits say they use stock ball joints and tie rods.
It sounds like you just need to decide which vendor offers the package that appeals to you. The spindles are probably identical.
