33's
« on: January 29, 2007, 05:06:32 PM »
I got an amazing deal on some 33in boggers that i plan on runnning on my suzuki..however it is compleletly stock drivetrain/engine wise besides a new catback exhuast...Now i definitly want to put in a spool to lock up the rear but what i dont know wether i should replace the ring&pinion gears first to 4.57s or some new T-case gears instead

As far as ive researched it seems as though replacing ring&pinions will do the most to take the stress over the drivetrain when running such large tires but im going to lose some major speed and possibly all of 5th gear...but theyre a tad cheaper...while on the otherhand T-case gears will most compenstate for the tire size allowing me to keep fifth gear however the stock ring&pinions will be left under a great amount of stress...

So should I go ring&pinions first?
or T-case gears first?

I may add that its going to be my daily driver...but it only has to transport my around town never reaching speeds more than 45...maybe 50, but doubtfully

You will probably want to do something about the birfields on the front axle. 33's are a lot of stress for that stock drivetrain. If you aren't wheelin' hard you should be able to get away with birfield rings.

I myself would probably plan on doing both R&P and T-case gearing for 33's. You could probably do the T-case gears and get away with it.

Remember that with those larger tires you will have alot more rolling mass so mileage and power are going to suffer.

its not going to be wheeled hard for some time...im just trying to get the project off to an ok start.  The most wheeling its going to see for the time being is just going to easy to medium. no rockcrawling in my area

I would go straight to a 6.5:1 or 8:1 transfer case kit.  My cousin put the 8:1 on his Samurai on 33's and has been nothing but happy with it.  I can go a bit slower with my 6.5 into the 5.12 on my SJ-410, but he can actually drive down the highway with his Samurai.  I guess those big block 1.3L engines really make a difference.  ;D

With light trail use he has not had any problems.  Most people like taking some of the load off the ring and pinion by dropping the diff gears at the same time, but my thought is if your going to break your birfs and twist axels first, then you shouldn't have to worry about the differentials until those parts are bullet proof.  :)

My boss has a sammi with 6.5:1 T-case gears and hes running a 33, stock axles and birfs...with lockers front a rear.  Nothing has broken yet on it.  The 6.5:1 work really good with 33's.  5th gear is usable and everything and its got some nice low gearing.  Cant even stall it out with the breaks in 4 low, 1st gear.

If you were to just do R&P you would be able to do it but it might be a little bit harder off road, sammi gears are pretty low but there not that low might bogg out real easy driving up things.


What i was going to do was put in the 5.14:1 gears in, drop some 32's on it, then when i get a yota front end.  Ill put that under the sammi change out the R&P (toyotas are cheaper) and run a 35 hopfully.  If i did the calculations right it should work out good, Im pretty sure that the 5:14 T case gears will be low enough for me.

The 6.5:1 and the 8:1 both have the same high gear reduction.  I think the 5.8 has the same high range as well, but I'm not sure.  So the only difference is how slow you go in low range.  :)

It sounds like you plan on building up your ride, just want to be able to run your 33" boggers while you do it. I say go for the TC gears.

I put 4.16 Rocklobster TC gears in ten years ago and just last year put 5.12's R&P gears in. It is nice to have a useable low range. It has had 32" swampers on it the whole time.  The R&P swap (other than relieving stress) makes it more driveable on the street with the larger tires.

Hey Drone637, I have a 3 cyl. swift/geo engine that would pep up that 410 of yours. Just think a big block SJ. ;D  And I live in the PNW. ;)

I have looked at swapping in a 3 cyl a few times, but the 970cc 4cyl. just wont die.  Plus, I get to brag about having a side draft carb that doesn't stall out when climbing hills.  It just wouldn't be the same if I had fuel injection.  ;D

I'll probably put the 1.6 from my Tracker in it some day, right after I get bored and put a V6 in the Tracker.   :P

Hey Phloop (or anyone),

I already have the 4.16 TCs, w/ 32"s on my Isuzu Diesel sami. The high gear is still too high to use 5th much.  ::)

I think I'll get the 4.57 R&P gears on rocky-road (unless I find a better deal), I was wondering what you thought about the "Master Overhaul Installation kits" they offer for $100 per axle...good idea? or can I save $200 and maybe afford a locker, along with the springs I'm getting (as my stocks just bent....diesel=heavy block)

Thanks..
Ciao,
Stephen
