Was going down this path late last year, but with fitting the price was stupid {front}.
The concept of just pressing a button really appeals to me, as for locking they all lock
its the way they lock thats different. One air locker I had was slow to unlock, I take it these are similar
with just a slight back off required to unlock on the go..
Having twin lockers in last 4x4 {spoilt} driving became boring or much slower, there fore
started looking for more technical stuff to drive on.
