yup... not on my fj.. but on my friends FJ.. me and ivan70 installed this kit on top of TRD bilstein shocks or the 5100... the only thing i don't like about this is the hardware that came with them..
I replaced them with M10 flange head bolts grade 10.9
here they are installed.
this is Dave's FJ.. with Bilstein 5100 set up.. 35" KM2s
here's Daniel's.. Bilstein offroad shocks silver and blue.. 33x12.5 tires
