View Full Version : UPDATED: Alloy Center Diffs

...After GPM went in the super-chunky direction with their version...


...and ATOMIC took the smooth techno feel...


...the 3RACING version is looking REALLY skinny...I wonder about the inherent possible flex of a low-profile unit like this one...


...In fact looking at the 3RACING version i wonder if you can even still use the gear cover? and isnt it missing a couple of points to secure it? I noticed the ATOMIC unit DOESNT have the lower attachement for the front torque arm...(I run mine up top anyway :)) but the 3RACING unit is missing all sorts of bits isnt it? PLUS it would help if they photographed it properly...DUH!!

Looks like 3 Racing took too much off. The Atomik one looks like it's adjustable!

...graphic mate i think you are right...Good work picking up on that...I didnt get it at all...wow that might be quite interesting...Pain in the bum having ANOTHER adjustment though..lol..

........I noticed the ATOMIC unit DOESNT have the lower attachement for the front torque arm...

ATM released a SSG plate set that includes the longer torque arm for mounting on top, I think that's why the unit has no place for the arm.

..thats exactly right TinTin ;) And their center diff is a litle tight on the slipper which would explain why they ALSO released what looks like an adjustable cenetr gear box...tricky fellows these ATOMICites...

Perhaps Atomic is thinking of offering different size slipper gears so we can easily play with the gearing? I'm liking that idea. :)

...well here it is kids...the 3RACING center gearbox in all its low-profile beauty...


...it fits great and actaully makes my stock center diff run better...I have ATOMIC diffs in the front and rear...This unit underwent the bleach treatment and hasnt been polished yet which is why it loooks yuk..It was originally blue...

...I have more pics but they are stuck in my phone for the moment...

...the diff is quite open, even when covered with the cover so that is a slight worry...but there is no flex...kinda weird because there are NO screws holding the two side walls together...it bolts to the floor with four screws in the bottom and one lower attachment for a pillow ball on the floor...The post off to the right fits nicely under the top plate...I dont use the stock top plate which is why it looks that open...

...Works great though...More info as i thrash it a bit...I will take it to Mt. Fuji next weekend and see what happens...

...Just in case you are wondering i prefer this unit to the ATOMIC unit...i still need to do a review of the ATOMIC one but basically it was a headache for me...The 3RACING was SO easy and simple and straightforward and the results were INSTANT!!! I am sorry i ever doubted this unit...I love it now :cool:

Nice....I like it. I wish they would make a new slipper....

Hi Bit,

Atomic just released 2 sets of slipper gears for you to try with the adjustable Atomic center unit :) http://www.stellamodels.net/catalog/images/AK53.jpg

They also realeased som other bits&pieces which are not blue, since they are made of titanium.... :p

I like that center bulk hub :)
Can you still use the gear cover with it?!

09-22-2005, 02:07 AM
Too cool. Those atomik gears are going make the Half 8 a much more versitile machine.

09-22-2005, 02:35 AM
...interesting indeed...I started a new thread about the benefits (or not) of the different gearing ATOMIC has introduced...

09-22-2005, 02:36 AM
...basically...but it is more open on the INSIDE side of the diff...a little bit of a worry...but the unit itself is feathery-light;...its just weird...you have to fit it to believve it...

09-22-2005, 08:01 PM
mmmmm... might give it a try then Bit

09-22-2005, 11:55 PM
...i checked...a stock cover WILL cover the unit nicely but it can only be secured at two spots and with the little curved flap in the spot...I had to take into account that mine has been cut and reshaped to allow for differnt little 'experiments' ;)

I'd love to see some pics of the atomik unit in your car, Bit. :) A picture is worth a thousand words, don't you know! :D

...sure thing graphic..I will pull them out of the phone tomorrow...i have to head out now but more time on the morn ;) BTW the atomic is for sale...20 USD shipped...
