We've installed a gaggle of the Currie anti-rocks, but none of the GenRights.
According to GR's site - they mention its 30% stiffer than an anti-rock and to use 1 swaybar instead of 2.
Are you running a front swaybar/anti-rock bar already, or planning on one?
The general purpose of running the F&R anti-rocks are to help balance the suspension so it cycles equally or near to equal as possible.
Dialing them in is key to have them work the best.
