Info is not the same, the difference between the 2, besides the price, is the Rod Ends on the NP17571 has the adjustable rods and NP17570 Rod Ends are fixed pivot points bushings..

NP17571 seem to be the better way to go..

I personally use the SPC..

I have the PRG UCAs and have blown out both the uniballs in less than 3 years - they don't seem to like the salt and cold that much. The powdercoat and heims are superb, though.

I have the SPC. So far they are as quiet and smooth as stock, I liked the ability to adjust both caster and camber without removing the control arm bolts. I also like the sealed ball joint and the bushings.

I don't like the massive boots on the ball joint. I have not had mine in for a professional alignment yet so I can't say if the ball joint boot is an issue, but at the moment I have about 5mm clearance between my ball joint boot and the coil bucket and I ground about 3mm of that off of the coil bucket flange. I think I may have a slight amount of positive camber (tops of wheels too far out), it is about 0.36 degrees more positive than it was before I replaced the factory control arms.

This. Except I replace mine about once a year, both of them. And no salt around here. Right now I have close to two years on them but they needed to be replaced a year ago. I just squirt some oil on them to keep from squeaking. I will never ever buy another set with uniball joints again period!

I've had my PRG for over a year without any rust issues...dealing with Houston humidity. They have been perfect thus far.
