Internal Ratio for JRX2 gearbox.

[Mad Racer]

I'm almost finished my retro conversion on my jrx2.

Need to work out my base line set up from the original tranny to the xx.

Thanks.

LRM tranny was 2.18

XX retrofit was 2.19 and 2.61 - depending which box and internals you have. It's stamped on the side of the tranny case..

Thanks.

I have the 2.61 Retro fit.

Will go off that.

Thank You.
