i honestly don't know how it works.

 

i would definately take the time to try and find a DID chain. ive heard lots of bad thinks about RK chains. i would also consider not going the 520 route and just sticking with a stock 525. you dont save enough weight to notice an improvement on the street and the 525 will last a bit longer, right tahoe? you can also consider re-gearing if you want some acceleration increase...
