GT Motorsports: GTM Rear Differential Cooler Kit
 

We would like to introduce our new differential oil cooler kit for all the hardcore enthusiasts out there. Heat is the main factor contributing to oil breakdown, and can lead to premature failure of your limited slip differential under extreme conditions. Traditionally a finned differential cover would be used but they usually only provide marginal improvements in cooling.

For the serious enthusiasts we have designed and developed a heavy duty differential oil cooler kit that will meet and go beyond your expectations. We know this modification isn't for everyone, but for the people that do need (serious road racing/drag/drift) we have it for you! This will also help extend the service life of your gear oil since it won't be getting as hot under extreme conditions.

We will have the basic cooler available as a standalone, with our aluminum shroud as an option. This shroud will help force air directly at the cooler, significantly increasing its performance, it also acts as a mounting bracket.

Another option will be a programmable temperature activated control unit which will control the pump to only come on once the desired temperature as been reached. This will increase pump life and avoid having the pump on when not needed.

This is nice. Is it up for sale on the gtm site?

How you doing George.......Thats really an impressive setup....

I'm doing well Mike, Thanks for asking - you know we can get one off these on your car with a little custom fab :)

George, pm me price and install. Thanks.

wow that is one great looking kit!!

How does the kit install to the diff? Does it use the drain and fill holes or do you have to tap it?

Judging pics, I am guessing they used some -8 fittings and put them into the drain and fill and then routed it to the pump/cooler.

Sorry, I was at work and the pics were blocked. Never mind.

Looking for this whole setup for an 05 G35 coupe. Will you guys be able to fab up a shroud for the G? PM me with info. Thanks:biggthumpup:

thats a sweet setup, i guess some shield of the exhaust wouldnt hurt either

George / Sam, does this kit use -6 or -8 hose?

Does anyone know the fitting sizes by chance? I am thinking the diff fittings are 10mm x 1.25 to -6an then run a reducer -6 to -8 to the pre-pump filter and then to pump, then the same back to the diff. Thanks for any input.
