The RCMAX 110mm clutch system

If your looking to go all out, we offer the 110mm clutch system for your 71 Supreme, this monster clutch
is virtually bullet proof but does come with some small fitment hurdkes to solve as below.

This fully adjustable clutch requires minimal maintaince but lots of tunability. To increase the engagement
rpm. Simply add pre-tension onto the 3x adjuster nuts to compress the springs. To decrease, reverse.

Stock settings for steel shoes on Baja/Losi/Hybrid = 21.8mm compressed spring length 
Stock settings for fibre shoes on Raminator/GOPED = 20.00mm compressed spring length 

Always adjust the 3x nuts evenly and check the spring
lengths after clutch adjustment to make sure they are all 
the same length (with proper Vernier calipers)

Clutch Removal/Replacement

Your engine will be supplied with a custom 110mm clutch pulling and service tool. See our youtube 
tutorial video on the RCMAX Official channel for detailed advice on how to use it.

LOSI 110mm Clutch install

Losi fitment is fairly simple with the 110mm clutch compared to 62mm. The only main difference is that
you will need to remove the rear-most fuel tank mounting bracket completely and cut the lug for this 
mount off the fuel tank. (pic below)
We recommend 36/56 Blackbone Gearing
