Different Wheels for JRX2 ???

[Mad Racer]

I want to run my JRX2 5 link but will perfer to run new 2.2 wheels.

I have hered that Duratrax Invader wheels fit.

Is this true.

Thanks.

Yeah they fit, but they get brittle wherever you use CA on them.

I just read through that entire thread, great info!
I am not quite clear on the " .125" wheel spacer ", can you explain this further? Do you mean the spacer behind the axle pin?

Can you show a picture of this, and/or give a part number? Please.

Dirt oval wheel offset spacers get sandwiched between the drive pin and the wheel, and change the distance or offset to the centerline of the car.

Kranzels, Customworks, Hyperdrive etc all manufacture such spacers from .075 to .225

Thank you very much for the "wheel spacer" info.

So, for the JRX-2 conversion, the B4 wheels are still driven by a drive-pin setup, as opposed to being driven by a hex adapter - it's just that the drive-pin is built-in to this 'spacer'. Right? ((as shown in Scr8p's picture))

exactly.
depending on the axles and size of wheels and spacers you are using you may have to use a low-profile style locknut to get it to stay in place as there are not many threads left.

So Jason, what's your complete combo there? (wheel spacer depth and brand? hubs are Losi 2038 for which car? spacers inside the hubs? B44 CVD's?) Mine is now with RPM 10GT rear hubs and B4 CVD's but the rear trackwidth is still a tad smaller than the front that has 10GT wide axles installed and the CVD's now go too far into the outdrives at full compression. Do you gain any trackwidth with these spacers?

in my above pic, those hubs a custom works. they're the same as the losi 2038 hubs in the hinge pin/hub area, they just don't have all of the ball stud locations. i never used the car with those hubs (i used the 2038's), i had just put them on it to make sure they'd work so i could give people another hub option to use on their cars.

i used the b44 cvd's, because as you said about your car, the b4 cvd's almost bottom out inside the outdrives during compression just sitting on the bench. and that was with 3 degree rear arm mounts. it would definatley hit with 1.5 mounts. but using the b44 cvd's, there's plenty of room during compression (see pic):

on the axle on the outside of the hub, i have the aluminum b4 wheel spacer, and a kranzels .125 wheel spacer. they'll add another 1/4 in. to the rear track width. i used them more for clearance at the front of the arm/bottom of shock, but the added track width was a bonus. it's pretty close to the front track width using the gt wide front axles.

Many thanks for clearing this, after playing a LOT with the different solutions myself, I really think you have the best compromise there.
