For sale:

OS Giken Super Lock Limited Slip Differential for NA/NB miata. Perfect working condition. Basically brand new with less than 1500 miles since installed.
Comes assembled in a 1.8 differential housing with a 4.1 final drive. Probably the best LSD available for Miata.
It's a clutch type LSD and can be adjusted to be a 1 or 1.5 or 2 way LSD.
The differential is still on the car right now, so feel free to come and check it out.
Housing, final drive, labor to assemble and the diff itself easily adds up to around $2000.

yum

 

I neeeeeeeddddd this. Why not 3.63s?

 

or coveted 3.33333333

 

Price reduced

 

If this was a 3.63 it would be a done deal.

 

@miataman04, you can always run this final drive on the new KMiata BMW transmission solution. Skip the 6 speed altogether and have a super cushy third gear.

 

Who was it assembled by?

Might help with the sale.

 

It was assembled by a local race prep shop in Los Angeles. Can provide proof for buyer.

Still available. Just want this gone!!

 

Price is negotiable, someone take it!!

 

Alright guys, someone take this already. It's a $1600 diff with marginal miles, and if the lash was set up correctly, you just saved yourself a trip to the drive train shop saving you a couple hundred more. This is a pretty good an uncommon deal.

 

Was this purchased through FM? Do you know how it was set-up or "tuned" and how that might compare to the "Supermiata" tuned OSG?

Also, shipping quote to 28173?

 

The big question is, was it set up for road racing or for autocross. This would make a big difference to a buyer. but this is a very good price for a good part.

 

It was set up for road race, and ordered directly from OS Giken through a local distributor. Sales pending locally. Thanks guys!

 

Do you still have this?

 

OP has the sellers phone number if you want to text them!

 

PM sent. Looking at my options throwing a 3.63 in this makes some sense.
