I agree 4doorSS, but only if the ones you start with are nice. Im with BallSS... if you live in the rust belt, chances are good that they are pretty well beat after 20+ years of X-mileage, plus combat with salt, calcium chloride, crater-like potholes, frost heaves, dried-out/worn bushings, and ball joint replacements. My experiences with GM's multi-platform-use stamped A-Arms, (here in New England), is that they are pretty durable, but like anything up here, you're miles ahead to rebuild with as many new parts as possible.
Being that the uppers and lowers are shared amongst many other GM platforms, this is the way many people are dealing with their vehicle's front suspension problems...
I stated the bonuses already with the "CK" Problem Solver version: the CK also includes the Problem Solver A-arm bushings, plus a bunch of other Problem Solver extras,... I'm fairly certain the Problem Solver Bushings are also Poly Bushings based on what Moog's own information states:
"Moog Problem Solver bushings are designed to reduce vibration and absorb noise. Advanced thermoplastic bushings absorb vibration and noise and deliver better handling and longer life, while providing the performance of urethane without the 'squeak' normally associated with it. They are not affected by oils, alkalines, ozone or hydrocarbons; can withstand extreme weather conditions; can carry substantial loads; and will not discolor or crack with age."
Whereas the "RK" version is simply better than OEM-Spec, and lacks the several key improvements/parts that Moog added to their "CK" version.
