Hey everyone, new to the zook world coming from hilux's and finally have found myself in a tiny terror, I've just picked up an 81 cab chassis lwb narrow track lj40, I have a few things I'm a little confused about, my rego papers model states it as a sj4081a and just after Abit more info on the model as I see people refer to there's as a sj410 and wondering where mine falls? Also it's a soft top and curious if that's a custom thing of factory? And I'm about to order the efs 2" kit and plan to take a spring out, will 31x10.5x15's scrub out on articulation and turning as it still has the NT diffs, hanks heaps!

Nice car, looks very neat.
that looks like a Sj51T with a custom rag roof and flares.

I could be wrong, whats your plate say in the engine bay?
Yes you will scrub, massage the guards with a hammer, your outriggers will need to be cut down too.

If it's a 1.0 litre, its an SJ40, so that's accurate. Yours won't be anything special, it's just had some work done to it.

It's had a 1.3 litre front clip fitted at some point.
Yes, the soft top roof is custom/owner installed. Interestingly, the SJ40's were prone to cracking their roof at the edge of the body lines pressed into them for stiffness. I've seen several with cracks. This might have been the trigger for the owner to make it into a "soft top"

Yes, 31's will scrub because suspension lift doesn't have anything to do with fitting bigger tyres. - it just changes the rest point of the suspension, not the extents, so in use the axle will move into the same spot it could without the lift.

31's are difficult with a narrow track car because they will tend to scrub on the shock mounts, chassis and inner guards. if you fit heavily offset rims to prevent this they will contact the firewall heavily (along with the headlight bucket area) because of the exaggerated scrub radius. a body lift will help but it's still tight (And doesn't fix the the tyres hitting the shock mount)

SJ40 and SJ410 mean the same thing, confusingly there's 2 different model code systems used by suzuki.

The first is generational and more specific.
SJ30=Sierra with LJ50 engine, JDM only.
SJ40=Sierra with F10a engine.
SJ50=Seirra with G13a engine, almost all narrow track diffs.
SJ70=Sierra with G13BA engine, wide track diffs.
SJ80=Sierra coily.

Dunno what the plan for the SJ60 was but it didn't seem to happen!

These model codes are suffixed with a letter to signify the body style.

SJ40= soft top with soft door
SJ40q= soft top with metal doors
SJ40v= hard top (V for van)
SJ40T= trayback which is what yours is

The other model code system is more broad. Lets break down SJ410.
SJ=sierra
4=4cyl
10=1.0l displacement.

So an SJ50, SJ70 and SJ80 are all also SJ413s because they all have 4 cylinder 1.3l engines.

This applies to other models that aren't sierras.
Eg
SE=1st gen vitara
SQ=jellybean shape Grand Vitara
SN=Jimny 3rd gen.
so SE416, SQ625, SN413 ect. These cars also all have their own much more specific generational model codes.

So yours is an SJ40 or more specifically, an SJ40T but it is also an SJ410. Still I'd be careful when ordering parts, yours is very modified.

SV is the "wide track" first gen Vitara
SQ is the jellybean shape Grand Vitara

Thanks heaps for the insight guys really appreciate it, maybe I'll stick with 30's for tires, and yeah the front end must be different tooas I bought a bonnet latch that didn't seem to line up also
