You can do that with a Lefty, just order it with twin sticks. You'll have one stick for high range - low range, and another for 2WD - 4WD, thus enabling 2-low. I have twin sticks on my FJ40, and have yet to use the 2-low option though - the only reason I did it on that truck was to get better mechanical lever advantage on that particular (Orion) transfer case. My Lefty is a single stick and I have never missed it there either. YMMV.Are you aware of any TC setups incorporate something similar to a 2lo?
Thanks FJNewb! Bring on the Tech. I can't remember the last time I was even in the general discussion Forum. We need more of this type of discussion.If nothing else at least it’s a nice departure from the, will this 16” wheel fit the FJ? Will this tire rub the body mount? What is that clunk I feel when stopping at a stop light? What to spend $xxxx.xx amount of money on (even though there is a thread which tells you exactly what to spend the first $2000.00 on)? FJ vs. Jeep (and why of course the FJ is always 300 times better)?, Will you keep your FJ forever?, How’d your FJ get its name?, 3” vs. 6” lift?, what did you do to your FJ today?, etc. If you haven’t caught my drift by now the majority of the threads on this forum are chit chat type stuff, redundant, or simply add little value in any way (except as another thread to appear in the search function and keep advertising revenue rolling in for the forum owners). It is depressing when this forums is advertised as the LARGEST FJ CRUISER FORUM and compare the lack of technical discussion on this forum to other offroad forums (Mud, Pirate, RST, GL4x4, MC, and many others) and significantly less than other automotive forums (hoda-tech, rennlist, 6speedonline, etc). There are maybe a few handful of threads posted in here yearly that I would consider “valuable resources” for FJ owners. The majority of those were started by people who rarely post here anymore (bellydoc, sbechtold, Sean K., MTBcoach, NCFJ, etc.) and others who still contribute some worthwhile discussion points (1911, Wikid, Layonn, Jeshua, FJinCO, MIGZ, etc.). Basically this is my last effort at trying to stimulate some new discussion on this forum.
I think that this important to note. If I didn't get such a good deal on my lefty (free) I would have added a crawlbox to my stock case. Mainly for having a middle gear ratio. Often the 4.7 is too low and the 1:1 is to high. Having that 2.56 option would be great.Marlin and Inchworm also offer crawlboxes (dual cases) for the FJ or a case which will mount to the OEM FJ transfer case. Your gas tank would need to be modified to get the Marlin & Inchworm products to fit.
I did the calc based on 5.29 gears. I still have not narrowed down exactly what axle/gear/locker combo I will end up with. It will most likely be larger than 4.88Wouldn't your final ratio be 218:1? (4.88 Axles * 2.28 crawlbox * 4.7 lefty * 4.17 Tranny = 218).
In Colorado we have plenty of rocks, dual cases with this combo are pretty common. My initial goal is to be able to have the ability to swap between 2.28 and 4.7 for most stuff. 10:1 once in awhile on big obstacles.I like the spread of 1:1, 2.x:1, and 4.7:1 (~10:1). Although I don't know how useful combination the 2.x:1 & 4.7:1 ratio is. That large of a crawl ratio will surely reduce shock loading of your axles and drivetrain (which seems to be the root cause of most breakage I've seen). However, it will put out more torque than your brakes can stop. I know Nick used his 10:1 ratio on part of the rock garden at Jamboree, but I guess that was the first time he got some use out of it. For the uber technical trails there might be value, but for the majority the 4.7 ratio seemed solid for the techinical stuff.
Yep, that's the main reason for that order. I could probably find a junkyard case for fairly cheap and either upgrade the gears or leave it stock and see how it goes.Good choice on putting the crawlbox in front of the Lefty. That way the Lefty case is only seeing half the torque load on the input shaft, compared to if you had them reversed...less chance of overstressing and breaking crap.
shhh.... It is in the plans (was going to wait a few more years, but those RST guys are starting to get to me). Most mods are on hold until I can get the money together to get it done.Ah, ditching the IFS I see?
Not out of the question, but leaving the cargo area alone is preferredSimple. Get this and do a 4 link rear...no issues with the gastank then.
Honestly, a triple case is not for me, but It would be cool to see it done, but not for me. I have been around a few mini trucks with triples. Very cool stuff. But yes, a better fit for a 22re than a 1GRFE.It'd honestly be easier to fit a Stak + crawlbox resulting in 6 speeds than triple cases (7 speeds). You could even keep the gas tank and I'm sure one less ratio isn't going to be a deal breaker. Most competition vehicles don't normally have more than 4 ratios. Only vehicles that I'm familar with that sometimes have more are the mini trucks, but more so due of the lack HP & torque they put out compared to modern vehicles.
Sorry, I just saw this.The whole point of posting this was so other (new forum members and simply those that are gear heads) could learn and have a discussion, not neccessarily for only those who are looking to buy a case.
So lets get some new discussion going in this thread....kick it off Ryan.
