Default C.I. 4340 steel; 5mm - Axial Transmission Outputs

Crawler Innovations is proud to finally offer our 4340 steel extended front & standard length rear transmission outputs for Axial transmissions. This is a permanent fix to weak outputs.

This new design incorporates the 5mm round with cross pin hole that all new Axial transmissions & axles now come with.

These outputs work with any manufacturers drive shafts that are 5mm.

These outputs are cut from 4340 "Chrome Moly" steel.

The reason the front shaft is longer is to move the drive shaft away from the spur gear. This added clearance allows for the use of larger spur gears in order to gear lower for increased torque & smoother start up. For brushless motors it is critical to ensure a smooth start up with no cogging.

They are sold in a set which is one long front and one short rear for $47.95

They can also be purchased individually.

The can purchased here:
C.I. 4340 steel; 5mm - Axial Trans Outputs





Here is a set installed on my SCX-10 based 1.9 scale Toyota. I am using a 96 tooth spur gear and 15 tooth pinion on a Tekin 13.5 sensored brushless inrunner motor using a Mamba Max Pro on 4S. The truck is as smooth on start up as my brushed 2.2 comp trucks using Holmes Hobbies hand wound motors.


Yes, it's a giant 96T spur gear but the smooth crawlability even with a brushless motor is amazing.


Here you can see just how much clearance you have between the output shaft, spur gear and drive shaft yoke. You could actually go bigger if you can find a company that makes a bigger 48pitch spur gear.


This pictures shows that the drive shafts clear all link mounting and links.

Excellent and finally Was hoping for more of these in 5mm. Any idea the largest 32p spur that fits?

It clears a Traxxas #3958; 32 Pitch; 58 tooth spur gear with no issue. It will fit a spur bigger than that, but the 58T is the biggest I currently have in stock.

Rc10GT 60t fits as well. Its just a touch thinner.


Eddie I just emailed you with a problem I ran into also.

I have been experimenting with several different 32P spur gears and pinions.

As pictured below, here are the parts:
Axial plastic trans case
Axial Slipper spur gear assembly
Axial top shaft & top gear
BWD HD Motor Plate
C.I. Outputs
RRP Steel Idler
RRP Hard Ano Output Gear
Tekin 13.5 Redline Motor
Traxxas 4927X Yokes
Traxxas 4951X Shafts

Spurs I tried with the combo above:
- Traxxas 3960 - 65 Tooth Spur = Fit the trans, cleared the yokes, but could not get a pinion to fit
- Traxxas 3961 - 68 Tooth Spur = Fit the trans, cleared the yokes, but could not get a pinion to fit
- Traxxas 3166 - 66 Tooth Spur = Fit the trans, cleared the yokes, but could not get a pinion to fit
- Traxxas 3959 - 62 Tooth Spur = Fit the trans, cleared the yokes, was able to fit a 8-9-10 tooth pinion (cool motor temps, hot esc, cool battery)
- Traxxas 3958 - 58 Tooth Spur = Fit the trans, cleared the yokes, was able to fit many different tooth pinions (hot motor temps, hot esc, warm battery)

Eddie are these only suited to the drive shafts shown or will others also fit. ie Junfac, MIP.

They are 5mm round and work with MIP's, Junfac, Integy, RC4WD, etc.
Anything that uses the standard 5mm shaft.

Got my outputs installed today. They look great and fit like a glove. Thanks for the great customer service

Ordered a set for the SCX10 today. I ordered two of the short outputs because I do not run smaller than the stock 87T spur so I don't need the extra clearance for larger spur. Eddie gave me a call and reminded me that only 1 of the outputs is threaded and you can't just use 2 shorts. Brain lapse on my part but, Awesome customer service! I appreciate the heads up from not having to order another part once I got it and realized I was air headed this morning.

Really appreciate the service and the awesome product you guys make, Thanks!

I have been noticing that in some of the AR60 sportsman builds, the guys are having to flip their rear axles to get rear driveshaft to lower link clearance. This longer "front" output could be put in the rear, couldn't it? I am thinking that this may lift the shaft just enough to clear and prevent interference. Pic is for reference.

And the design evolves again.

CI team drivers will be testing a new 7075 aluminum version of this design.

CI will also be offering front and rear long outputs in the new design.

The finished machined dimension has been changed on all outputs. The new end measurement is 4.95mm, just a hair under 5mm. The reason for doing this is for metal drive shaft users. I received a number of emails and phone calls about the last production run of outputs. Those comments, concerns and ideas were applied to this run of outputs to improve the product design.

The new design of outputs should be in the CI store sometime next week.

Awesome! Glad I hadn't ordered mine yet I'm assuming the price is going to change... If so what's the new price for them?

Is anyone from CI going to Axialfest? I think I want a standard length front output for my SCX-10.

What about those of us that already have a set. Any thought of offering a service to tune up the old version?

Are the screw holes 3mm or stock 2mm?

There will be a slight price increase. More machine time = more money. I have not been given the final cost yet.

I am working on a exchange program. I have costs that are yet to be determined, so that will have to wait. However, the idea is to exchange old design outputs for new ones.

2mm, just like they have always been.

I will NOT be doing an exchange program. The set up cost for re-machining earlier design outputs is impractical.
