hello, I've exhausted my resources searching for stock replacement for my rear springs. I dont know what the stock specs are so I'm having a hard time figuring out what im buying. Just trying to stop the rear from sagging. Is there a big difference between these two shocks??

well I'm no expert, but the first set are moog front springs. listed at 518lb of load weight. The next listing is for moog rear springs. Moog is not performance oriented, like other brands. They deal with factory replacement, not performance upgrades.

the spring rate is 104, I believe the 1st set are rears and the picture just isn't accurate
