i bought these spacer from calmini about 2 years ago.... i also bought some rancho shocks from 4wheel parts. i installed them and the 2.5" lift looked good. 4-6 months later my shocks blew..... i got them replaced for free under the warranty. i put the spacers back on and another 4-6 months they blew again. got a another set replaced again. this time i didnt put the spacers on.... i dont if the spacers were the reason for my shocks blowing??? is it the shocks that dont support the spacers????
