Mugen MRX3?? will MRX4 gears fit?
 

Hello

Will the 2 speed gear's from a MRX4 fit a MRX3??

thank you for the time and effort in advance!! Jesse Franklin

I believe not, if I am right (it is already a while ago) the MRX3 gears are mounted with a circlip. When using the MRX4 1st and 2nd gearbox adapters it will fit.

The pulley set of the MRX4 will fit, the big rear pulley is smaller on the 4 but there are spacers included.

Yes and no. No they will not directly but if you replace the one-way and two speed housing with MRX4 parts, then yes they will.

Yes, mrx4 spur gears will fit fit into mrx3.

However, you need mrx4 1st one way housing and 2nd gear housing too.
