PN Ball Diff: http://www.rckenon.com/public_html/shop2/catalog/product_info.php?products_id=4179

Looks pretty cool. :cool: Comes stock with 64 pitch gears, light weight stainless steel shaft, V2 pressure plates, and ceramic diff balls. The diff shaft it comes with is not the brand new ultra lightweight shaft, but is lighter than stock nonetheless.

I wish the diff came with a 52t spur. Thats pretty much the only one I use... Looks nice, although not too fond of the color.

I have been testing that shaft for months and that shaft is SICK! Lightest shaft ever made for mini-z! and I don't feel any torque steer, bending, twisting from it. It feels just like the steel shaft except you can gear your 64 pitch to 3.7 gear ratio and still have the power when coming out of a corner just like driving a 4.0 gear ratio.

fyi....try the 53....@ the sweden regional i gained 2 kmh on the track with the 33t pnwc motor by going from 52 to 53.....
the color is close to pn orange....but it also serves another super secret purpose;)....get one....you'll love it.....

I have tried the 53t a few times... I just prefer the 52.

Super secret purpose... :rolleyes: now I have to get one to find out the secret...

I just got some of the Qteq diff parts in from Reflex too, which look really nice. I need to find diff rings for them now... None of my ATM or PN diff rings will work.

The thing I can't stand more than anything on my r/cs is aluminum parts anodized in different shades of the same color. Drives me up the wall!

This super secret purpose better do something super amazing if it's gonna bug me everytime I look at my Z. :rolleyes: Come on... what's it do?

EMU, let us know how you like the the Qteq diff stuff.

just sand down the qtec plates and then you can use normal diff rings . it sux to have to do that but unlees you have 3racing rings it will not work.

that color is Hard Coat anodize. The coating puts a hard skin on the shaft making it harder to nick or mark. The shaft is not only light but it is durable....

And they hard coat anodize the shaft in normal PN colors??

hard coat has its own color and depending on the grade of aluminum that is the color you get. Softer aluminum takes a deeper color. the range is from a dark gray to a greenish gold.....In my industry(pharma machinery) we hardcoat many components.

That's interesting. Thanks for the heads up.

Hmmm....Why doesn't the brand spanking new light weight ball diff comes with the ultra light weight diff shaft? I assume they are coming out with the ultra light weight ball diff? Soon?

Ordered a new PN diff and shaft to test...

I also ordered some Kyosho plates and o-rings for the Qtec diff... Going to try it on a 3Racing shaft, or possibly the PN ultralight shaft for extreme lightness... I may have a 3Racing diff around somewhere that I could pull the plates for as well (have 2 Qtec packages).

When you get the ultralight diff shaft can you check to see if it fit Kyosho diffs please.

I'm going to have to get my hands on the Qteq parts, I got to their site a few minutes to late, those parts look sweet though.

They all come at a cost. . . money and time to tune them.

I will let you know how it fits. I assume that it would be compatable.

I tested out the Qteq parts that I got tonight. I disassembled an old Kyosho diff for the plates and o-ring. I had to do a lot of sanding to make it 64p compatable. Although you only have to sand one side. I used a 3Racing ti-shaft, and it went together without a hiccup. I noticed a little difference from my Atomic vII diff with 64p coming out of the corners. But it is very slight... I must say, that the diff looks really cool. I glued the plates to the holders so they dont slip... just a small amount of glue is needed. It is a little harder to make adjustments without a pin to hold the adjustment nut as you adjust the left wheel. You can do without the pin, but its a little more difficult to hold the nut.

That new orange is the same as Hudy products.

Bought new Diff and shaft and is smooth as butter and works great. Diff alone at its price is a steal.

The alu diff shaft are absolutely incredible. Works really good, and helps a lot regarding accelleration/ braking.
Changing the pin from an old Kyosho diff shaft was no problem.

EMU is the glue you used CA ?
THANK YOU!

Yea, same glue that I use on my tires. Just a little bit to keep the plates from slipping...
