I've been reading of some people experiencing some vibrations with a 2" rear shackle drop. I was considering this, but if there is a vibration I am a little hesitant. If there is a significant vibration, is there any way to correct it?

Pinion angle shims will correct it...the vibration comes from the pinion angle being changed from the drop. It's kind of hit or miss whether you'll get the vibration or not...I had a vibration prior to lowering my truck, and a leaking front diff pinion seal. After the drop, both seem to have been cured...go figure.

get a 2* shim from any suspension shop (off road or street) and it will correct the problem. make sure you install it the right way too, if you put it in backwards it'll just make it worse.

I think only ECSB trucks have the vibration problem after a 2" shackle install. Although shims would be a good idea for all trucks, it is not necessary on RCSB and RCLB trucks. My truck does not have a vibration problem.
