You have to use the entire diff assmebly if you use mugen stuff. As you found out the diameter or the outdrive shaft is different. To me it would be worth it to get them as I am really digging the different gearing. Small tracks I use a 16t and use 17t clutch bells on bigger layouts. One of our US drivers used to use the OCM truggy gears but they stripped easy, and now are just about impossible to get. I never ran them in the EVO but I think you will like it.

I just put some mugen bulkheads into my OCM truggy and they seem to work well. It took some time but they fit pretty good. They do change the feel a little bit but not enough to really slow you down. I had them lying around and figured they would be a better fit with the mugen truggy diffs I was already running.

Someone posted about using the TQ bigbores, I will agree that a different set of good quality shocks will make a big difference. I use the mugen shocks which are not super big bores but they work really well and the fluid stays clean.

Thanks for the info. Did you use the Mugen diffs at all with the OCM bulkheads? Based on my test fit, I can tell I need to do some light dremel work to the chassis and inside of the OCM bulkheads. Are there any more problem areas I might encounter?

Anyone interested in KMW big bores for the OCM. They have machined brass pistons, and the insides of the shock are honed for smoothness. They were about 130 new. I will sell for 65 shipped.

I used ocm bulkheads[truggy] and the moo diff is a direct fit. Had to put 1 shim on non ring gear side and one shim on pinion. I thought the hole spacing on moo bulkhead was different than ocm, I bought a moo skidplate and it wouldn't line up boltholes.

I did use the mugen diff assemblies in the OCM bulkhead on the truggy. The bearing holes are never the same on the ocm bulkheads and wear out quickly because of it. I did not want to ruin good moog diffs so I used the moog bulkheads.

They are not a direct bolt in, you do have to do some dremel work on the ocm metals as well as 2 chassis holes. I even had to take just a little off the shock towers and I mean just a little.

You might have different shock towers. My OCM Truggy and Pooldocs OCM have different shock towers on them then each other. They are really similar but different.

I just tried that setup today and it is truly amazing how much steering it has. I actually think I need to tone it down some or at least settle the rear end down. Any suggestions?

yes got to work on it, but I busted my tank last we.
and I just gave my spare tank away..

did you use 3.75 rear toe and 2.5 front rollbar?
you could try 7000/7000/2000 and lighter shock oils 500/400
and just 0 insert at front inboard toe

my friend Vman uses 12000/8000/5000 and says
it locks the buggy more in...
gonna test 7000/7000/2000, even 7000/3000/3000
7000/10000/5000

I used this exactly as printed:


I think I might also try dropping the rear camber link on the shock tower and possibly add more front caster (move caster spacers to the front of the arms.

going softer in the shocks helps too
550/500 or 500/400

Thanks, I'll give those a shot as well. I didn't mention but I am using the stock rollbars.

Well from what I can see on my OCM truggy, this is the setup that Alan Burton was running last right before he left as this was his race truggy.

Upper arm position- 1.5 Lower hole
Upper arm spacer- 2 thick ones on rear of arm
Steering knuckle- inner hole
Rear upper arm- center hole on tower, middle hole on upright.
Rear upright pin- upper hole
Rear anti-dive- upper hole
Diffs I do not know.

My shock positions you can see in the pics. He did not have shock mounts so I do not know where he had them

BTW THOSE ARE THE TQ RACING 16MM BIG BORE SHOCKS ON THE TRUGGY. PERFECT FIT AND I HAVE THEM IN STOCK. MADE A HUGE DIFFERENCE COMPARED TO A STOCK SET I PUT ON IT.

THESE SHOCKS ALSO FIT THE EVO BUGGY TOO.

putting in 3.75 rear toesettles the rear
