suzuki lj 50 diff swap

[ALS4B]

I am thinking of swaping my suzuki diff setup to bizzard diffs and coils all round would my 3k and 5speed have enough grunt to drive it no rego

Would the 3k drive them , sure , the axles will make the lj a bit heavier but its the size of the tyres you bolt on the outside that could slow it down some what .
Also what year diffs are you looking at ? The factory coiled diffs or diffs from a rugger/blizard ? The factory coiled out of a prado are ok as they have a standard diff head in them ( but not the diffs you are talking about I suspect ) . The blizard axles are a different story . They have a really crap ratio of 3.3:1 , I think an lj would be around 4.1:1 . Also there are bugger all aftermarket parts for them , ie no ratio changes etc and I believe lockers are hard , if not impossible , to get .

I assume you have considered the hassles with the lj (if factory ) outputs being in the centre and the blizard are off set .

If you only plan on running a 3k then maybe the blizard diffs are a bit over the top , maybe a set of 413 or samurai diffs would be a suitable upgrade , a bit lighter , can get different ratios and lockers etc .

If you are after some width and a bit of strength and need centre diffs try this , run a vitara rear diff ( wider that a toyota , stronger than an lj and set up for coils ) . Get two 413 front diffs and run two long sides , ie cut off one short side housing and weld on the other long side housing . I think this would come out very close to the width of the vitara housing .

Have fun

i have the diffs out of the bizzard here, the only thing i thought that they would be stronger and had the 5 stud pattern on that bolts up to the lj pattern checked the ratio last night it seems to be about 4.1 i think with a lsd in it . the lj 50 is only used as a mud pugger ,trailer every where

I was going to fit a set to my diesel powered samurai as it needed gearing up , don't hear that too often eh . But never got around to it and sold it . It was fast of the line , beaten many an fxgt but it tapped out at about 120kph , just ran out of revs .

The killer is the 3.3:1 ratio . From 4.1 to 3.3 is like 25% gearing change . like going from a 30 inch tyre to a 37 inch tyre , would expect that would be too much for a 3k .

Guess thats why they are so cheap .

oh yeah rip the body off put in a motor with a bit more grunt make a bit of a body to sit in will be a mean machine
thats if the chassis isn't cracked

That all depends on your budget and what you want to do .
Stay with the 3k .
- how many axles have you broken ? Is it worth swapping ? Then look at a set of 413/samurai axles , wider stronger and only the offset to sort out .

Going bigger motor ? Do you have the blizard diffs ? - scrub that , just read you have . Then I would look around for a low ratio 413 transfer case , called a rock hopper or 4.16 etc . Put this in as it will sort out the offset and the extra reduction in the t/case will be offset by the higher diffs in the blizard axles . ~$500 if you get a second hand one .

Width and strength , go the vitara rear and fab up a wide 413 front . Bit of work but really wide on a lj , measure first . Not sure on cost of vitara rears , can pick them up from pick a part cheap enough then need two 413 fronts , can keep the short side cvs as spares .

Next I would say a new engine and gearbox combo , pretty much anything will give you the offset for toyota axles , strong and lockers etc .


My pick , the vitara / 413 axle combo but thats just because I like doing something different . Best practily since you have the axles , get a 413 low ratio t/case and install the lot .

Must put your gearing right out of whack. Resulting in a weaker driveline.

I have a mate on the look out for LJ50 Diffs to re-gear his 410 for 31" tires

[ALS4B]
