Overall the quality of this kit is pretty good. It comes with black coil spring spacers with Teraflex logo in white, 4 aluminum bump stop extenders, and 4 bolts for use with the bumpstop extenders. The idea of the extenders is to remove your OEM bumpstop cups and place the aluminum extenders in between them and the frame mounts using the provided longer bolts. The bolt length is the same for both front and rear however the bolts needed for the rear have to be longer as the ones provided will only barely thread. This is not necessarily a serious issue but it is however a detractor to the value of the kit in my opinion. I have usually been very pleased with Teraflex products, this time I am a bit disapointed so Im rating this kit average as I have used coil spacer kits from other companies which came with everything needed and it all fit correctly for the same price if not less.
