Hpi RS4 2 nitro tranny
I have an hpi rs4 2 nitro and I want to install a two speed tranny. Since the tranny is discontinued, are there any similar trannys I can fabricate to make it work?

I have a few of the stock HPI 2 speeds and 1 ofna 2 speed for the HPI that Im willing to part with. Let me know if interested and make me an offer. I convert all of my RS4s to single speed but everyone I've ever purchased seems to come with a 2 speed.

I assume your ofna 2-speed is from an OB-4?

I checked that part 86038 and I noticed that the shaft doesn't take an e-clip but instead it has a semi half moon shaped. The type that would accept a drive cup joint. Which is part #72161. The RS4 2 version takes an e-clip! Something's not right!

i have a new in package heavy duty 2 speed trans part #72516 for your nitro rs4 2. willing to sell if the price is right

If you really check the websight of Stormer'sHobbies. You'll see there are C-Clips laid out on the photo of 2sp Tranny. HPIz238 are the c-clip you are talking about. 13mm C-Clips, not E-clips and Stormer's do have in stock. Refer to HPI RS4 18SS that uses 2sp tranny, HPI websight. I prefer using 2sp tranny Stormer's has which they have, Part are discontinued. It tell you where you stand with the model.

You most definitely aren't looking for hpi part #86038, the only hpi 2 speed trans listed on stormer's website for use on rs4's. The clutch parts may be interchangeable but the shaft where the trans components rest will not accept the belt drive pulleys. You should consider buying a used one if you plan on using one yourself, since these parts have been discontinued for quite some time, a new in package trans sells for rather high prices. Even complete used trans go for around ~$70, whereas the 86038 complete trans for the rs4 3 goes for ~$60 new at stormer. I've 2 hpi nitro rs4 2's, and have recently checked into the same thing, and ended up catching a good used hd trans for for a little less than I anticipated.
