Seems to be both the
--->4670 optima over drive
--->4672 optima under drive
But I also have 46 and 48 t gears.
How do you swap the plastic? Press the metal part to split in two?
Also have 4738 Final Pinion
Probably going to use these in my Optima Pro build.

A while ago I won these 48 pitch gear sets made by trinity for the ultima & optima. I'm thinking of using one in my ultima runner but am having difficulties figuring out the gear ratio. Surely a gear ratio table existed but it didn't come with...

Last post

A larger spur allows you to use smaller pinions and still reach the spur. Doing so will bring the final ration for both closer agian, so that makes sense.
My guess: the overdrive kit was intended for stock moters.

I never had any issue with the...

Why do these go for so much? Are they just rare of do they perform better? I'd like to put something worthy in chris's tranny.

Last post

Just saw the set on eBay and they're not worth that much. :x

They've mostly sold for a third or less of his price in the past.

What's the durability like on them? I picked up a couple basket case goldpans and to my supprise both transmissions have 48p gear sets in them.. I was thinking of using one set in my 6-gear runner 2s lipo with a 13t brushed motor. Think it would...

Last post

I have seen some of the outdrives eventually get rounded out where the bone rubs. I have also seen that on some rear axles, so I assume it's not strictly related to the hardening on the thorp stuff. Otherwise, the gears are nice and smooth.

First post

I just scored this on the 'Bay...I hope I'm not mistaken, but isn't this comparable to the OT-76 Hard Final Pinion Gear? I confirmed with some searching that it's made out of steel.

Part # 4738 info:

Last post

Just a quick confirmation--received the gear today, it's an exact match for the stock OT-41 gear. It's made of steel however, and is significantly heavier than the stock aluminum gear. As OT-76 hard final pinion gears are few and far between (and...

First post

It occurred to me that I could probably build a complete Turbo Optima (maybe even 2) with all the spare parts I have. The only things I'd be questionable on are all the various screws, nuts & bolts, and a set of shocks. Are there any aftermarket...

Last post

I used a RC Screwz set with my Ultima restoration and they were fine. Just get a nice set of full size individual allen wrenches - makes it so much nicer.

Yes it does..directly. not so for the optima mid.
However you must re use your old 3mm middle bevel pin to hold in the 2 small bevel gears.

Last post

OK, thanks, Ill order some up. The new optima has a bunch of good parts for old cars. Almost worth buying a whole kit and parting it out.
