I am currently running the Teraflex 2.5" coil lift with shock extensions on Rubi shocks. I also have .75" spacers installed for 3.25" total lift. I am wanting to purchase the Teraflex 9550 shocks now but I am not sure if I should go with the set for the 2.5 lift or the set for the 3-4" lift. I have a chance for a really good deal on a set of 3-4 so I am hoping I get feedback that is the kit I should go with. Lol

 

compressed and extended lengths are what you need to look at. They can be very different for different brands and knowing what you actually need by measuring full stuff and extention length will tell you what you need to know. Basing the length off lifts heights will surely be wrong.
