Howdy. Has any body has done a 5.1 ring and pinion (from a Vitara/Escudo front diff) into the front and rear SJ413? Iv done a bit of research on the Internet and either it’s a straight swap or you gota use a “Retainer Sleeve Kit”. Also there was something on 2 and 4 spider and they were swapping the center as well ???
It’s a club truck with standard running gear.
Oh and are the SJ413 front axle bearings and steering seals over the counter at my local bearing shop or do I have to know a guy who knows a guy. Ha Ha.
Cheers MIKE

I never got a straight answer on the internet either . You have a few options .
Firstly the vitara carriers are 2 spider . Apparently in the vitara the ring gear sits a little further over , not sure if this is due to the thickness of the ring gear or not but some recommend a spacer , others say it can be taken up in the carrier bearings . Also the 413 ring gear retains the pinion shafts that hold the spider gears , due to the shape of the vitara ring gear they are not retained anymore , so a retainer of some sort is needed .
As I could not get a retainer ( that day ) I ended up using an arb locker carrier , solved the problem .

If you want to run just the 2 spider carrier of the vitara in the 413 diff you would not need the retainer . Not sure on the strength of the 2 spider carrier but could well hold up . test it for us

If you bring in some retainers let me know I could be keen for a coulpe .

Yeah, was looking at bring in a lower gear set for the Escudo transfer but money woes and the exchange rate make a 600 dollar purchase over $1000. Inc post.
But these Retainers we are talking about are only $35US. Spose I need 2 of them, to do each end of the SJ413. That’s $150 inc post. Still … couldn’t have the parts made for that price.
My mate has a coil sprung samurai. Is he in for the same drama, as he has 5.1 diffs ready as well?

Ill need to think up some sort of supper bull shit to spin the wife to double up the order.

Cheers again MIKE.

I've looked into this myself.. Heres a good write up & detailed install.

That’s a better write up than this one. Thanks. http://bbs.zuwharrie.com/content/topic,3975.0.html

He will not be able to do it as the coily samurais have a different
diff design.

Well then he’s not going to be very pleased.

Now looking for a rear dif center for a SJ413 or just the side gears.
Gona put the 2 pin Vitara centers straight in as is. See how far that will get me.

What size tyres are you guys looking at running?

5.1's set the gearing about right for a 33" tire with stock transfer in a 413.
But does nothing to resolve the crap stock low range ratio.
Add reduction gearing and your ratios go way out and you need to run bigger tires to correct it.
Any thing over 32 is a good recipe for snap ,crack, bang with stock diffs, axles etc.

4.6 ratio vit R&P would be a better option IMO , allowing for 4.16 transfer gears and would put the ratios right for about a 32" tyre.
4.6's are pretty rare here in nz though.

the word on outers / auzookers is that a vit front 3rd member is a bolt in swap in the front (ie 21 spline) . no real strength issues with the 2 pinion , but the alloy housings are prone to cracking.
Ideal would be the rare steel 3rd members for a straight bolt on swap. rear would need the side gears swap to 26 spline.

my 2c

Also GV and X90 3rds will apparently bolt straight in as well

Yes. Got a steel 3rd in the front of my Escudo. Only got 30-inch tiers on the SJ413. Looking for a cheep fix to do better at club champs. Are only aloud 31inch tiers for nationals if I ever get there. If I break stuff then will need to go back to the 4-spider center.

cheapest fix would be a 410 transfer case . corrects the gearing for a 30" tyre and gives you a little reduction in low range.

Rocklobster (4.16) tansfer is the best fix for a 31" tyre.

IMHO 5.1's and a 30" tyre is going to be a crap combination.

Y?

Completely over-geared. no control with gearing while going down hills , will make transfer gearing worse .Should spin the wheels nice but no slow technical ability. power producing band of engine will be right in between gears . etc etc.

Every driven a truck geared for 35's with 31's on it? they are a dog to drive.

my 2c. was always taught to gear a diff to suit the size of Tyre you are planing on running.

I nearly understand. It’s like following a silage chopper with a 400-hp truck at 5km/hr. Or trundling around a hay paddock in a truck picking up hay bails with the elevator bolted to the side and 3 people on the back way up high trying to stack.
A low gear surges too much either to fast or to slow. And when the paddock has a hill in it the tiers are more likely to spin up. Very hard to match the speed you need.
If a higher gear is selected, throttle control is easier and torque is transmitted more accurately.

Thanks UBZ your opinion is well received and to my A list.
