I would guess R160 suretrac. It's the only one with the step on the side there.

just to add for posterity's sake, the differential is also axle specific, eg, if swapping make sure both cars used the same halfshaft splines. although i suppose you might be able to interchange the side gears in an open diff.

Please note the 4 spider gears.
As corrected on the same thread on Nasioc, the double stub axles (asymmetrical) were used in all Ver1-4 era cars REGARDLESS of the type of LSD used. Over that time the majority were the early type VLSD as you show above, but also included a factory clutch MLSD (Ver1/2 STI-RA) and Suretrac MLSD (Ver3/4 STI). And again...ALL of those required the funky double splined axle.

Suretrac. Curious if you have the symmetric or asymmetric axles?

How much is it worth? It's for sale at a local JDM importer

Is it different than the VLSDs that came in the 00-01 RS?

WAY different than the RS VLSDs, and way better in any situation.

The RS LSD is the weakest option of all the possible LSD's. If you read the OP you'd know why. SureTrac is the very good, and very expensive option. The only better option (IMO) would be older clutch-type, but they're rare because they were an option (not standard equipment)

Hmm. They are asking around $300. I'm reading on other threads that they require special axles as well as the USDM RS axels won't won't? Any truth to this?

Ask yourself this: How much is an LSD worth to you?

To me, personally, I wouldn't spend that money. Simply because my (rs style) VLSD works okay for what I use it for (hooning in the snow). If I was an avid autocrosser or road racer looking for that additional edge, or if I just liked having rare parts, it would certainly be worth that much. It's very rare, very good, and therefore very expensive.

But I'm a cheapskate, and my VLSD cost $75 from a junkyard.

So really, it's up to you. Is it worth $300? Absolutely, to the right buyer.


P.S., it's got axles in it in the picture, so talk to the seller about getting them with it as a package deal.

Someone should re-host the FSM on SureTrac diffs!
