That is an extreme condition. Not being familiar with Syncros, what does the "locker" do? Lock the VC? The 4x4 drive truck I had years ago with locking front hubs, locking rear diff, and a "hard" coupling between front and rear had the wheels turning and churning equally, each getting 1/4 of the full power, but this is only useable at low speed in extreme conditions. Would the locker mated with a Peloquin limited slip diff equal this on a Syncro?

Inquiring minds want to know.

Got stuck on the flat in similar snow. Very hard crust and about a foot or more of soft loose cold snow below. Locker and mod aggressive vc didn’t get me further forward. Got backed out finally.

Maybe chains on the front would have helped but the crust acted like chocks.
