Never heard mine until riding in back seat. Lifts been on 3? Years. Have to make bushings for rear shock bolts when installed make me think rear shocks.

I sent MusclezMarinara a quick PM asking about if he had any issues while driving with them. In the mean time I will order the KK springs today

Just an update, I got the new 731 springs put on last night and no more noises at all, the KJ springs were making slight contact on the bottom metal, this was the noise I was hearing. I threw in an extra Iso as well to help level it out. Im now 22" on all 4. Rides great.

I was surprised on how different the KJ springs are compared to the KK springs, the KJ where taller and heavier gauge steel, yet the KK springs ended up giving the same lift...

I will be putting the springs I took off up for sale shortly to help recoup a bit.
