Lock right can't make my up?

Right as the subject says I can't make my mind up wether to get a lock right or not? My jimny is close to the way I want it to be! Except a rear diff lock, I have done a lot of research and reading on here about them and how others get on with them. My problem is my jimny has to be used as a second car of sorts and will have to do about 40 miles of road driving a week! I would really like to hear people's opinion's and experience of them on the road! And before anyone says I simply can't afford a selectable diff lock until next year!
Thanks Andy

Simple. Just do it! I'd happily do 200 miles a day with a lockright. And I do average that a day, just not in the jimny.
Its the best mod possible.

iv beed pondering the same i know its worth it off road but

1, on road how does it handle, like a car with LSD rear? if so thats fine.

2, is there any increased tyer were from road use with a lock right?

Just do it stop f#@king dithering lol

Iv got a lock right and I think it's a awesome piece of kit. You get some strange noises from them at times but that's normal. I did a 8 hour round trip on the road to go laning with the north east boys and it was totally fine with the job. Just buy one its only £200 and its money well spent. Hope this helps with your decision.
