I installed the CPP sway bar kit earlier this week. Makes a big difference.
I encountered a few issues with the kit.
Two of the supplied bolts were supposed to be 1 3/4" long grade 5. The kit came with 2 3/4" long grade 8 bolts. (1" too long) No big deal - I happened to have some spare bolts of the correct length on hand.
The instructions do not mention the shock mounts. The shock mounts attach to the same axle U bolts that the plates for the new bar's links attach to. You have to remove the shock mounts and sandwich the plates between the axle and the shock mounts.
The holes in the plates that attach to the U bolts were poorly drilled. Simply re-drilling them on the drill press did not help as the spacing between them was out by at least 1/8". I had to elongate one hole with a file to correct the spacing. I used the shock mount as a template to mark where the hole should be.
No insurmountable issues, really.
