OEM 4.30 Limited Slip Diff 41110-60A61 (2 Viewers)

[Cruiser Weight]

This is a long shot.

Has anyone used this differential for a pre-2016 Cruiser geared toward faster off-road travel (i.e. Baja and fire roads)?

I can guess, but I'm curious about how the truck actually rotates with this setup with the center diff locked and unlocked.

@bjowett mentioned this part number, and I believe he mentioned the clutch packs could be tuned.

What did @cruiseroutfit use on the Canguro truck? A spool, or...?

Thanks!

We use an ARB rear locker. The full-time 4WD and center diff would work splendidly with a LSD rear imo.

The preload spring for the clutch packs can be shimmed or replaced, which will provide more pressure on the clutches. Additionally, the housing can be machined deeper to accept more clutch plates. The issue is that we have not done any testing to see how much more bite the diff will supply.

A Torsen is probably a better bet.

I installed this Torsen in the rear of my 2021 LC200, about 8k miles ago. So far I like it. Turning all the stability controls off makes for good drifting on sand, but there was a moment last trip to Carrizo where I got sideways at speed with all the nannies turned on which made me curious whether the LSD action exacerbated the situation.

Interesting...

@gluaisrothai, why did you chose the Torsen over an OEM choice?

I ask these questions because I've read about potential issues with both the ARBs and Harrops - tools I might need 0.5 percent of the time off road.

A limited slip would function 100 percent of the time (potentially with Toyota's OEM reliability) and perhaps make the truck more fun to drive. The only time I've cursed over not having a locker was holding up a group at the Tip Over Challenge on Hell's Revenge. Frankly, I may have been able to figure it out had I understood crawl control - I hate electronic aids, but I can force myself to learn.

The truck is heavy and powerful, so I think small tweaks in the diffs carry a lot of weight transfer and effects. I'm thinking about a limited slip rear diff with a front locker to maximize my benefit for my time/labor/cost and to minimize my time working (and re-working) problems that don't need solving.

This truck was supposed to be a comfy tow rig for my autocross car. Oops.

Thanks for your thoughts!

Yeah no worries. I suppose it was mostly just an individual preference. Technically the higher bias ratio of a Torsen seems to make sense for the application where you might find one wheel with little to no grip- that’s where a conventional LSD doesn’t play well without preload. Excess preload can create challenges as well, like when both rear wheels are on an icy surface.

The Torsen is a lower maintenance item with no clutch plates to wear out. The Speedmaster is also sold under the Nitro brand and seems to have a good reputation.

Someone also pointed out that the Matt’s Offroad recovery team generally use Torsen LSDs on their builds vs lockers. Not sure if that’s a good data point but it’s a data point

The more and more I think about it, the better the limited slip option sounds...

Were there any hiccups having the Speedmaster installed into your diff?
