I like coming home to presents like this! No, I haven't put them on yet as I still have a final left to complete in my technology education class, but they will go on this weekend. First impressions . . . these springs are bad ass full military wrap up front, and extra protective leaf out back and no wussy spring clamps like the J.C. Whitney springs. I ordered the 3 inch ones, but they sent me the four inch springs, no biggie I guess. These things use 18mm bolts which is freaking huge!!! I can' t wait to put these on! I will have a write up this weekend.
