They are releasing two under drive ring pinions and one over drive R&P in addition to the stock ratio. All three are listed on RPP but not yet in stock. In addition they are releasing three additional spring rates for the TRX4 shocks.

They look great. I like how both gears are well marked! No more counting teeth.

"Two" under drive R&P's??

low and lower? If that's the case what a spread in ratio you could get!

I'm all for more options but $40 a piece for straight cut gear sets seems mighty steep.

My stock gears are still in great shape so I can wait for Hot Racing or some other company to start cranking out gears that are nearly as good for 60% of the cost.

RPP is listing the stock r&p but no ratio info then they list two underdrive 11-34 and 10-35 as well as one over drive r&p 12-33. I can't find the stock r&p ratio at the moment and the TRX4 Parts and Accessories page is not currently on the Traxxas site for some reason. It is possible that the new 11-34 r&p is a replacement for the stock gear set but they still list 4 gear sets total on RPP.

Well then, it looks like they are releasing three machined r&p sets one OD ratio, one stock ratio and one UD ratio.

Interesting idea. You know what I'd really like to see, though? OD/UD gears for *other* Traxxas vehicles. I'd like to bias the AWD setup in my 4Pede to drive the front wheels a little faster, since that's what happens anyway when the truck is driving through grass. (my 4Pede has a center diff.)

Got mine installed with the Traxxas lockers. Over drive front and Under drive rear. Fit perfectly and good mesh.
