Offroad Trailblazers and Envoys

Lunchbox Locker in the rear

Dumping ground for offroad Trailblazer or Envoy general discussion.

Who has a lunchbox locker in the rear axle of their jeep? I have heard mixed feelings of it in the back, with noise, behavior, and lifespan being the big topics.

It will be in a Ford 8.8, so the strength of axle will not be a consideration. The appeal of the lunchbox style locker https://10carbest.com/lunchbox-lockers is the price. For a little over $200 for an Aussie, it doesn't seem too much different than a Detroit Soft Locker, which is like $600 for my application. I know the design differences between the two, but I'm not sure it is worth the double in price. DANG, an Ected selectable is cheaper than a Detroit! What gives?

I've got one in my TrailJeepBlazer.
It's not an ideal product, but there is more good than bad. I would much prefer a selectable locker over lunchbox, but lunchbox over open diff.
In soft sand/mud, sometimes unlocked will be easier to keep the vehicle moving. Parking lots and slow speed turn i hear the inside tire chirping, but it's not too bad. I drive rather conservatively, so mine has lasted 4+ years and 4 cross country trips and hundreds of miles of trails.

I've also got a lunchbox. I like it, but my TrailJeepBlazer also isn't my DD.

What selectable is cheaper?
