replacing bushings on aftermarket susp parts?

[chmercer]

i am planning on getting some cusco rear upper arms for my s14 and was wondering about the quality of bushings that come with a product like this? or if the product somehow eliminates the need for bushings completly, i.e a pillow ball? cant really make out from the picture, pretty small but maybe somone can tell?

no need for bushings with those arms. i believe they use pillow ball for the inner part of the arm, and bolt into the outer stock bushings

No bushings. Suspension pieces like those are engineered to reduce the slop inherent with bushings.
