They work fine on the street, just chirp a little around corners.. and wear out your tires a little..
I hate Lock-rites.. noisy, and unpredictable on the street.. yukko..

ARB is the best answer though
and you are driving me crazy calling it "Rear lockers"  one Locker per Axle... lol... I am easily annoyed.. HAHA.. ignore me...
Lock rites are NOT limited slip. A limited slip works on a clutch principle.. it's NOT a locker. It does just what it's name says it does... allows LIMITED slip in the differential.
Do you understand how an "open Differential" works? and why they are needed? If not, you should do some research, so you will better understand how this is all related.
Dangerous on wet or ice or snow, because BOTH rear wheels will turn on ice, and will put you into a spin more easily, especially around a corner, as one wheel HAS to slip or slide. If you don't understand the "why" here.. You should look up "differential" on the internet and get a basic understanding of the system. If you do this, you will understand how each different kind of traction aid works, it's drawbacks and strengths.
