      Are you sure I'll have to go with Fox Shock's 4" to 6". I just went to the shock's and someone ask if they'll fit Rock krawler 3.5 lift kit and the answer was no, that I'll have to go with the smaller shock's.

      • This kit recommends shocks that closely match an optimal length suggested by Rock Krawler. For a front shock with a 3" bump stop, it is 17" Collapsed to 29" Extended in length, and for a rear shock with a 3" bump stop, it is 17" Collapsed to 27" Extended in length.

      We purchased this kit for our 2017 JKU Chief. We opted to go with the Fox 2.0 Performance front and rear shocks and Rock Krawler front and rear bump stops. Will we need to replace our drive shafts? And if so do you suggest replacing both or just the front?

      • Since you have the 4 door the Rock Krawler 3.5 in. Flex Lift Kit System would not require new driveshafts no.

      Does this lift kit come with shockes

      • No, the Rock Krawler 3.5 in. Flex Lift Kit System will not include shocks. You will need to shocks of your choice with this kit!

      Helpful (0)

      assuming this kit is matched with lets say the Fox 2.0 shocks for a 3" lift would these springs need a bump stop extension or are the factory ones long enough?

      • With the Rock Krawler 3.5 in. Flex Lift Kit System Rock Krawler suggest front shocks that are: 17" Collapsed to 29" Extended and rear shocks that are: 17" Collapsed to 27" Extended. This would be Fox 4-6" rated shocks, not their 3" shocks. It would be suggest to use 3" bumpstops with that shock size as well. Pending on your tire size you may be able to go a little smaller or larger to prevent the tire making contact with the fender.
