Interesting, never come across this before...it's listed on their website. Is anyone running this?

GReddy precision cast aluminum Differential Covers prolong the life of your limited-slip differential, by increasing oil capacity and cooling. Internal baffles control oil slosh, while an integrated 3/8PT port can be used for external cooler for extreme usage.

Application:

S14 / S15 Model with R200 Differential

Skyline GTR R32 / R33 / R34 with R200 Differential

Nice find

looks like what BMW ( or was it Alpina and aftermarket places ) used to do with their rear diffs and sometimes oil pans. The fins in the aluminum help in cooling.

Air cooled VW's run cooling fins, but there would be about three times as many. Also did they say how much it costs? It might be nice to have. Plus it looks good.

It's 33,075 yen which is roughly $274.82 at the current yen rate of 120/$

I could get these shipped to you guys for $320

I don't see why it would matter much - the other half of the housing holds all the bearings and take all the loads.

It pretty much just holds a bit more fluid for better cooling and lubrication, it won't make you diff any stronger.

Personally I'd slap a thermal sticker to me diff first and see how hot it gets. The stock diff is heavy enough to begin with. No point making it heavier and adding oil if you don't need it.

I like the ports for a cooler. I dont know if anyone would every need it, but it sure has a gee wizz appeal to it.

A lot of skylines run these with an external cooler because of there 4 wheel drive and active traction control

How could you run an external cooler without pressure from a pump?

rx7what

iTrader: (6)

they run a inline pump out the bottom hole into a cooler and then back in the top hole. I have even seen them have electric fans on the cooler. It looks pretty bad *** on the R34 gtr nissmo Zspec. Ill see if I can find a pic.

Here you go. You can see the coolers under the rear bumper.


If you want to see mor epics of this car go here.

i think those are the fill and drain holes, not ports for an external cooler.


if they're for external coolers, where are the fill and drain holes? maybe i'm missing something

Aware of the Greddy cover for a while now. Rich, I believe RHDJapan.com sells these.

+1. I've run my car up on the lift in July after some long drives but never noticed the diff cover more than just warm. A decent synthetic probably helps too. Of course it could be a different store for a tracked car.

At any rate, they've been listing them elsewhere lately too.

Those diff covers aren't too hard to find in the US. If nothing else, it's something else you can polish up on the car .

I know Nissan guys frequently run diff coolers, both Skyline and S-chassis cars. Small electric pump to cycle the gear oil through the cooler. I want to say some Nissan car came with a diff cooler stock as well.

This is one of those parts that's neat, but I'd have to know that I needed it before I'd spend the money. If you could find out that the gear oil in the diff is getting too hot, sure. I think you could really only get it that hot from serious track use or drifting. REALLY not needed on the street.

Jim, you find all kinds of odd ball stuff. Next time I need a part, I'm coming to you!




Also, if you follow the link to the japanese website above, you can clearly see the two cooling line bungs and the drain plug for those doubting they were built to run with a cooler.

Good find Rich, anybody actually use this yet? And what, if any are the benefits? I can't see our diff getting that hot.
