Which one is the correct rear shock for a 2-3" rear lift?

OrangeBeast88 said that he used RS999190 but according to the advanced auto website it says that they wont fit and that the upper and lower mounts are different. Their website says that RS999301 fits a 2.5" rear lift on a Colorado.

I don't NEED the extra length of the RS999190 but would rather be a little future proof in case I add a little more lift.

the only difference in the mounts is that the RS999190 probably does not come with the upper bar-pin mount, but you can easily re-use the ones from your stock shocks...

I use these... RS999190 Fit just fine, but I got 4" of rear lift

Came out of the box like this... :shrug:


999301 will work or 999325(I think) for 2" to 3" lift

The 999190 are for Silverado/sierras I think but they fit just fine for 4" or 5" of rear lift

Well, I have 2" shackles and a 1" AAL and plan on replacing that 1" with a 2.5" leaf.

Hmm...

Well, decided to give the 999190's a shot. Probably won't be installing them for a few weeks but I'm excited to try them out.

I just installed these today. They are awesome! They are beefy as hell also. I took a few comparison pictures. I had one of the RS999301's because I had originally ordered them but one of them came with a broken adjustment knob. That was what prompted me re-thinking which shocks to get. I also compared them to the KYB GR2 that suspension maxx sent to me which was for a 2" lift rear.
