<div id="post_message_2244190">Has anyone tries switching the Heavy Duty Gear set to High Speed and Low Speed? Are these gears make any difference in speed?</div>

For the axial?

I put the high speed gears in the front axle to get a little overdrive to pull it onto the rocks and it seemed to work pretty good.
it didn't make a big difference in speed but it helped the crawling ability.

It is cool to know. I'm new to rock crawler, and have AX10 Scorpion. Having a high speed gears on front axial only, will it causes uneven speed on both front and back axials?

You don't want to have that for regular driving, but for crawling it gives the front an extra pull to help prevent flipping backwards on steep climbs.

I dissagree. I've had a brushless system in my crawler with the OD gears in the front and it drives nicely on dirt, almost like a front wheel drive car. The difference in ratios is ~15%

To get an idea for what it will be like you can put larger diameter tires on the front axle. (HB rovers front, Rock claws back is ~15%)
