I have a 2011 Silverado 1500 with a rcx lift in it. I also have a Maggie supercharger on it. The rear end seems to move quite a bit and with 7" blocks in the back I figured it probably would. Anyways I was planning on doing the rcx traction bars that bolt to the frame and mount to the axle but then I came across the cal tract bar and assassin bars and thought they might work better but I haven't seen anyone run them with a lifted truck. Is there any pluses or minuses of them? Thanks

 

Damn that's a big block, look into a shackle flip to eliminate some of that block.
I run 50" cognito traction bars and they helped alot.
