|  New big bores
Want to learn a little about big bores. Just started using some factory-assembled XXL big bores and was surprised at how much resistance they have. How much of this is "new stiffness" which will go away with use? What weight fluid does Traxxas put in these? If I have to change oil it would be helpful to know what the starting point was. I'm using these with firm Mini-T blue springs which take a few seconds to expand the shock to full length. Like slow motion. I'm guessing that's not the norm. Do most people drill out their pistons or change to a piston with more holes? Or just change fluid? |

Traxxas doesn't label their bottles of "silicone fluid", but persistant internet rumors have it pegged at 30wt. I installed the big bores on my Slashes, mainly to keep the caps from flying off, but also for the fancy gold shock shafts, too. They work great on vehicles that jump, like Slashes and eMaxxes, but for a crawler you may need a piston w/ more holes. They'll free up a tiny bit as the o-ring seals loosen up, but not all that much.

Drill teh holes in the pistons out, or put super thin oil in them.

How heavy is your crawler? Is it a shafty or MOA? Scaler? Need more information  |
