Is VLSD in Sport Package really useful ?

felix0121

I read an article saying that VLSD has low effect among all LSDs, and is usually used for low-HPs.

I don't know exactly what range of Horse Powers the author meant by 'low-HPs', but I just got curious about my VLSD.

So does the VLSD included in Sport Package really help for better driving, or it is actually not so useful that I cannot expect too much from using it..??

Which is a fact ??

Well, considering your vlsd will just be an open diff after about 60,000 miles or less they arent far off lol

Do you mean that VLSD will be not working after driving 60,000 miles around ??

As the internal fluid breaks down, the limited slip effect becomes less and less. At roughly 60k miles (lots of variables, but that seems to be a good rule-of-thumb figure), you don't have much LS left.

Thanks for the explanation.

Until now I've done my best for all maintenances, and now hitting around 130K miles, I believe I must have gotten the VLSD fluid changed whenever needed.

Then if the fluids were changed properly, is it pretty useful for street driving? (I don't go to a track, and mostly I drive very mildly)

the fluid for the actual LSD itself is separate from the differential fluid that you drain from the differential. basically once the fluids in the LSD break down you have to get the LSD rebuilt

Then now my VLSD is useless even though I've followed everything on the Nissan maintenance guide ??

If yes, then it does frustrate me .. OTL

Time to upgrade to Cusco LSD.

So you're sayin my VLSD @ 80,000 miles and 10 track days is prolly not LSD-ing anymore?

Think of it as a wear item like your clutch.

There's some great upgrade options out there =)

Love my OS Giken! The aftermarket stuff requires a little more maintenance.

If what the others are saying is correct, then your LSD is about done.
Vote Cusco!

Mine has been done for a while, you can feel the on/off feeling of the vlsd when going through high g force turns

I'm just gonna replace mine unless I go ahead and buy the Nismo? I'm 15,000 miles from that point.

I thought its oil was wear item, so I followed the maintenance guide to get it changed whenever needed.

But I didn't expect the VLSD itself could be a wear one.
