I really like how you view all details and double and triple check everything. Despite the work and challenges involved you make buying a NOT triple locked LC look like not a bad idea as long as you don't mind installing the air lockers. I have heard the ARB air lockers are really great units and basically almost never fail unless installed incorrectly. Many say they are better than the E-lockers that usually come stock. Happy to finally catch up on the LC videos.

[@D3fender110]

Great videos man. Enjoying the details and help for others ✌🏼

[@ИльяПискунов-г2г]

As always, very educational, thanks

[@familyvid1]

A 4-inch slab serves as the basis for comparison in this chart. With a 50 percent increase in thickness to 6 inches, the slab's bending strength is more than doubled Doubling the thickness gives four times as much bending strength. double the strength for 1200 difference. Great investment.

[@NKPGarage]

Nice work! The build is looking great!

[@RM_Garage]

Thanks!

[@s13koop77]

About to tackle this exact upgrade next. Great vid man 🤙🏼 How about air system/plumbing next? ARB? Viair?

[@RM_Garage]

Thanks! I was thinking the ARB twin unit so I could air up my tires too.

[@s13koop77]

@ good call. Probably make for a simpler install too. 🤙🏼

[@ИльяПискунов-г2г]

​@@RM_Garage Using arb twin for 8 years. Great for 37" tires, you,re right

The beast ❤❤

Poor little spider, as an Australian i disapprove of the dispatching lol

Shim-ception 😮

[@klaus110894]

Awesome 🎉 what's the link for the nitro 4.88?

[@RM_Garage]

Check the description of the video! Edit: wait…thought I had a link in there. Google “nitro 4.88 gears Toyota Land Cruiser”, I think customoffsets has the kits. Revolution is good too and yotamasters has them.

No Super!?!??! Greetings from SF

[@rjmacay]

nice

[@brantschenkrealtor]

Give it’s a paint looking wrap

[@RM_Garage]

Maybe in the future. Mechanical stuff more important to me for the time being. Definitely would like it to look good too!

[@brantschenkrealtor]

@ totally agree!

[@speargearreviews.7809]

Shouldn’t you freeze the bearing to put it on? Heat expands metal?

[@RM_Garage]

If the bearing is to slip over a shaft, heating the bearing expands it to help fit it over a shaft. Freezing a race can help.

[@Emayarceeo]

Greetings from Aus! How much mpg/Lper100 are you getting with the rebuild brother?

[@RM_Garage]

Before the gear upgrade, around 8.5mpg or 29.4 liters per 100km. After the gears, not sure. Haven't tried yet!

[@erichvonarnim8732]

Did Nitro give you a reason for the different bearing they gave you?

[@RM_Garage]

Nope. Nitro is impossible to contact to be honest I didn’t even try. It took them about a month to even ship these gears and it was a difficult experience trying to contact them. Eventually they showed up and the quality is good….id say the bearing is probably fine and that many would use it with no issue. Just didn’t sit right with me.

[@erichvonarnim8732]

@ I would feel the same about using that bearing. Great video, I am collecting parts to do the same install.
