Long Distance with Interlock On?

Your diffs will overheat very quickly. They aren't "four wheel drive" they are for reestablishing grip once you lose it in the snow or mud. I've been told, most differentials have safety locks that prevent them from being used in high range (this includes the power divider).

And if you aren't driving in a straight line, you will shred your tires.

 

I have never encountered a speed/gear restriction on a power divider. Diff locks, yes, but they're a different animal.

 

My 2001 Sterling had full lockers, and they'd plumbed the override to kill both the diff and power divider locks. Didn't take long to rectify that problem!

 

I've spaced mine off and left it on for 500 miles. I've run purposely for 500 miles many times in bad weather with it engaged. I've never disengaged / engaged it unless I was sitting at a complete stop.

I has a Pete mixer that would automatically disengage it at 50MPH while moving. Even throw the switch on the dash back over.

And yes it makes it suck more fuel.

 

I always go 80 mph downhill in snow, disengage interaxle, hit jake on 3rd stage, at the bottom of hill I awlays turn hard left. If still sliding, I apply 90 psi at least on brake pedal. Take it from someone that's been there

 

Let me guess... this is in the Pacific NW, and you're from the Carolinas?

 

lmao!!

 

The Jake brake has NOTHING to do with the interlock that is on the engine.

 

dude this statement has my mind twisted. Can you explain to me what you are talking about? I'm not being a wise ###. being serious. Jake brake has everything to do with what axles are locked in

 

I always thought that the inter-axle lock was between the two drive axles.....never knew it was on the engine.
Go down a good grade on slick roads with the Jake on full, and let me know what it does.
