42mm Bottoms Up Brass Bearing Scale Rotor - Sold in PAIRS

These are intended for 2.2 wheels.
But have been proven to fit some 1.9's without any modifications.
And other 1.9 or 2.2 wheels with slight Modifications.

PLEASE MEASURE YOUR WHEELS BEFORE ASSUMING THEY WILL FIT.

Some wheels just need a SLW spacer to help the Brass part fit behind the bolts.

42mm x 12mm

The pair weighs 134 grams (4.7oz)

SLW Hub Compatible, Center thickness 1.0mm so it wont add much width to your track width.

Pre-assembled Press Fit. (you CAN take the bearing out if you really need to, but why?)

LIFETIME WARRANTY!!! Keep that bearing oiled with very light oil.

But if your bearing fails for ANY reason, send it back and I'll put another one in free. FREE!!!

Want to run weighted scale rotors, but don't want all that rotational mass? ME TOO!!!!
That's why I designed these.
Stop robbing that power from your motor.
Stop breaking parts.
Stop worrying about it. The FIX is here.
Add these to your setup, to add the weight you want, down low.

Without worry about the wear and tear on your truck.

BONUS: ALL While being SORRCA LEGAL !!! AND adding valuable Scale points !!!!

MAKE SURE TO WATCH THE VIDEO !!!

SOLD AS A PAIR - $39.99
Want extra Scale point? Add a pair of the Ultra Light rotors for the back axle. $17.99 ($2 cheaper than by themselves)
Want your rotor to spin Extra free? For $10.00, We will run the bearings in for you on our bench jig at 6,000-8,000 RPMs to seat it.

This takes us a bit of time, that's why the price goes up by $10.00

You can do this yourself with a hand held dremel tool and a Sanding Drum (without the sanding part on it)

What is the back spacing on these rotors?

[Bottoms Up]

Its about 0.450
You need to be running a 0.475 hub in order to clear the knuckle.
Or it could be a smaller one if you are running a thicker than standard 12mm Hex.

Any idea when these will be back in stock?

[Bottoms Up]

I have a few in stock.
Message me on Facebook, I don't get on here often.

Very cool product! A reminder that if you made the aluminum insert reach 1/8" further , it would clear VP 1.9 wheels without changing the wheel offset. I used spacers from Brian, but its a lot going on between the wheel, spacer, rotor mount, and hubs.

Thanks for the suggestion JRH.

Maybe on the next batch.

Super cool product, I'm running them on MST Portals with 1.9 chanquish wheels, just needed a thin SLW hub spacer to work.
