More Harm Than Good? Toyota Diff Drop Truth vs Myth

Every video you make is gold.

As a layman with an interest in engineering, thank you for being an engineer willing to communicate with us laymen. Specifically, I appreciate your willingness to address common misconceptions in a way that is undeniable when the complete set of variables are observed, not just individual parts being talked about as if they exist in a vacuum. Your clear and concise explanations allow you to touch on things that other experts might understand but not be able to articulate to others who are learning. On top of all this you have superb video quality and a likeable personality. Excellent work, my friend.

This man has the most logical and well thought out insights of when it comes to using your vehicle.

Get this man a tv show. Most informative off-road content on YouTube

Just found your channel yesterday as I was looking for information while working on my FJs suspension (replacing factory components with new OEM stuff for now). I love how detailed your videos are and how they are backed up with the math and physics to prove it! I've learned a lot as to what each component does and what to look for as I do my maintenance! Keep up the great work!

As an Off Road instructor that just watched 4 of your videos , I love all of this ! I will definitely tell students about your channel ! Keep up the great work !

Love your videos! Last year I bought a 13' 4Runner Trail w/ KDSS I am slowly building into a capable overlander for 4x4 camping and technical off-road trails. As someone who has yet to throw thousands of dollars at a lift I am so grateful to have found your channel to clear up myths and internet rumors about 4Runner/Toyota lifts. I would have HATED to be $3,000-$5,000 into a build only to find i over spent on something that made me lose articulation and off-road performance. You have used science and thoroughly explained points to help people build the most efficient and cost effective off-road machines. I'm always excited to see new videos get released by you. Thank so much from Sacramento, CA!

Straight to the point. No long introduction or annoying music. Very informative. Subscribed.

I knew it!!! In one of the 4Runner forums on some thread I read a couple years ago, a guy had some issues with his steering, went to a toyota dealer and took one of their top technicians for a ride in his 4runner, they talked about his issue and got on the topic of the diff drop, the tech explained at great length why the diff drop can actually cause a series of issues all related to each other, going back to the diff drop. I have been looking for that thread for a long time now but still can't find it. But since reading it, I made up my mind not to get a diff drop. This video confirms my decision. Fantastic video as always man!

Your channel is so amazing 🤩 thanks for sharing such an in-depth analysis on this topic. I learn something every time! For my FJ I haven’t ever installed a diff drop and never wanted to due to the complications it would have with my front skid plates. But your explanation makes a lot of sense, and now I have zero reason to install one! Thanks!

Your videos are the best source for Toyota 4x4 technical info on the internet by far. I'd love to see a video analyzing the sliding sway bar disconnects for non KDSS 120s. They seem like an interesting compromising for keeping a sway bar.

Great video! We also tell customers a diff drop is not needed. 1" more travel beyond an extended travel shock will run into other issues in addition to CV angles. Ball joint or uniball on UCA will usually be maxed out.

Your videos answered all my questions I’ve asked myself and others in the past 12 years.🤔 (Purchased ‘08 FJ in ‘11) 👍🏼

I could watch you, and AMD at The Car Care Nut all day. Very thorough!!

I've been on the fence for months about getting a diff drop and finally found your video! Now im not ordering a diff drop and going to mesure my front suspension angles haha. Thank you so much for being so in depth and informative! You sir have gained a follower and respect!

Man, some really in depth and well presented info. So much effort into demonstrating the concepts. Well done.

Amazing content! Finally someone sharing good info about lifts and susp/steering/driveline geometry 👍🏼

Another excellent discussion. Glad you addressed the "real" diff drop, i.e., Phatt (and similar) from Australia. I came to a similar conclusion as you did that the 1" spacers really don't accomplish much.

Thanks for putting the message out! I been singled out in the past as the crazy dude yelling at the clouds but you’re putting out the evidence, ground clearance is everything when riding on IFS. Thanks for the videos dude, hopefully business takes off so I can become a patreon and buy some of those sweet knobs. Again, thank you Kai!

Man, you have some great videos and explain things to us normal folk very well and easy to understand. Thank you for your time and effort making these videos!
