What a professional! No errrs n' aaarrrrs, no derailings, just perfect execution of message. Subscribed!

By far this is the most comprehensive yet simple explanation of different differentials. Thank you, Ben.

I've come back to this video multiple times over a couple years. Amazing video.

Who needs years of TAFE and schooling when you have guys like this presenting in a way that is super easy to follow and actually retaining the information being shared in such an impactful way, being visual? Thank you for this share!

[jeffreydunn]

THE best off road differential description ever. This presentation doesn't go overboard with sponsor support. 100% mechanics, installation, application and engineering. AWESOME video. Thank you!

[Faolan]

No "ums/errs", just well spoken information. Excellent presentation, excellent descriptions!

[mikehartmann]

Still relevant and full of good info 6 years later. Thanks!

I've been offroading for over 30 years, I have never seen a better explanation of different style traction devices!

Had a Detroit style locker before in a light vehicle. Annoying to drive both on road and off road.
On road it was the worst if not being driven correctly.
It would lock in a tight turn if letting off a little on the gas or started to engine brake.
Needed to keep a certain amount of power or freewheel else it would lock up shaking and unsettling the car with screaming tires.

Off road one felt there was lot of play in the system when in rock or uneven terrain. Very jerky because the wheel has to turn a little before power would be transmitted in the opposite direction.
Every time the car would get over to the other side of a stone it would move an extra foot rolling before engine braking worked because of the huge slack in the system.

It worked best when driven "hard" because then it would always behave like a spool.

Probably the most rational and clearest definition and explanation of how these things work. I'm not a mechanic but I now I understand

Thank you Ben! I was sold on an Eaton e locker but after watching this video I am seriously considering an ox Locker now.

This is a really incredible video. One of the best I have seen on YouTube for any subject. I just want to add that we have front/rear ARB lockers with 110K miles on them, and zero issues except for a melted plastic air line that was replaced with a stainless steel line. No leaks, no icing, etc. We can air up our 2 gallon ViAir tank (110PSI) and the ARB compressor won't trip (90PSI) for ~6 days. With front and rear locker *engaged*, and the Jeep parked, the compressor won't trip until ~3 days. Without the ViAir tank (we have a shut-off valve on the supply hose), the ARB's tiny manifold/tank will hold pressure for over a day before the compressor trips, and about 12 hours with the lockers engaged while parked. Note that we don't typically leave the tank aired up due to condensation and such.

Anyway, thanks again for the awesome video.

Finally understood how TOR SEN diffs work. Thank you.

[DiHandley]

At last, someone who knows what they’re talking about and presents it in a way that’s easy to understand. Brilliant!

[anthonyforgey]

This has got to be the most thorough explanation of difflocking options. Really helpful

I wish all YouTube videos were this good. Heck, I wish any YouTube videos were this good. Thanks, Ben.

If anybody is wondering why there aren't many vids on this subject, it is because of this video! ....very informative and very professionally done. Nothing beats a well presented, well constructed vid when broaching this sometimes confusing subject. Well done and many thanks.
