  • Rock Krawler 1.5" Spring Budget Build

    When this all started, There was no 1.5" spring available for the our jeeps.

    There is a sweet spot for this level spring for people who are trying to do certain things with their trucks, but are not trying to go nuts with them.

    You can build a very cool jeep without spending a lot of money and in this thread we are going to show you how.

    Here is a picture of Black Betty, who's mods are out of control and beside her is "Lola"



    Lola is a Sport. Her owner has taken the first step by replacing her tires with the stock rubicon tires BFG KM 25575r17.

    So she's starting to look a little meaner, next we are going to put her 1.5'' RK springs in.

      grab the used ones if you think you might want to go bigger down the road. Part of me wishes I had gone bigger. Maybe in the future when the girls are a little taller. Test drove a 2014 JKU with the Mopar stage 3 lift kit and it felt really nice. But I don't think my little girls could get in without me picking them up.

      I'm in the same boat. I have a 6 month old and occasionally my wife drives the jeep. Add in the cost of regearing for 35s and it's just not in the cards right now

      The good thing about the RK kit though is it uses the same control arms up to a 3.5 lift. All you have to do is trade out the springs.

      This was one of the main reason I went with RK.

      I'm thinking of this lift. I currently am running stock Rubicon suspension with MCE flares. I only want 2" of lift. I run an extremely light Jeep with no winch. I want to stay as close to stock geometry as possible and have floated the idea of just an AEV spacer lift. I don't do any rocks. I ran an AEV 2.5" on my last Jeep with same 315 DT's and MCE's. Gap was ok but made the DT's look a little small and the suspension was stiffer than I want. How stiff are these 1.5" coils. I rode in a RK 3.5" that I felt was too stiff.

      In my opinion they are very soft. I am running rancho rs9000xl shocks which are adjustable and allow me to fine tune the ride.

      I just need to decide what version I should go with. I don't want much more than a couple inches. I was also looking at the OME 2" lift since they have different spring rates for coils.

      The RK springs are stiff. They are made to handle the weight of a winch and steel components. So with nothing on them, they will feel stiff.

      That way, if you want a winch in a year, they won't turn to mush under the weight.

      If you want to stay as close to stock as possible, and no wheeling in mind, id say do the spacer and keep all the stock stuff in there. Its a cheap route too, so if you hate it, you spent $300. and you will know. Rather then spending more changing everything, Springs, shocks, and THEN finding out that you hate it.

      Thats the route id suggest.

      I like the compliance of the stock suspension. I had an AEV 2.5" on my last Sport and was impressed with the handling, but some times felt it was way too stiff. I will never run a winch. I just don't do that type of wheeling. The Rubicon is way more than I needed, but its so much better than my Sport was in every way.

      I guess i should qualify my reference that the springs are soft, compared to the lift in my prevuous 3/4 ton truck. I expected the ride to be rougher but really didn't notice the ride being rough. My coworker has a terraflex 1.5 performance lift and waiting for him to get it installed so we can compare the ride.

      I would love to hear feedback on the TF performance kit.

      I went ahead and ordered the TF leveling springs. I was told after I purchased them that my Rubicon with 17/59 combo wouldn't see any lift from it. I should get them installed this week so we will find out how much lift I get.

      Here it sits with the TF Leveling Springs. I'm very happy with how it looks and it drives slightly stiffer than stock, but in a good way.

      Here is another before and after. I really like how level it is and I could actually probably run a small 37" now as well.

      Looks great, which LOD bumper is that? I am trying to figure out what bumper to go with.

      Its the LoD Armor Lite Shorty. The whole thing weighs almost exactly the same as the stock bumper which is what I wanted . I had a PS Brawler Lite on my Sport and I always hated how far it stuck out from the grill. The LoD is so much better and looks awesome IMO.

      Thank you, did you have to relocate the vacuum pump when you installed it?

      We put one of the LOD armor Lites on Jesse's Girl.

      Where is Jesse? He knows weather or not we moved the pump.
