I have been driving the heck out of this rig for the past month or so, with little issues. But, there were a couple things I wanted to change/add. One was our OD ring and pinions for a little more wheel speed. I also replaced the stock 3 link with our 4 link parts tree for added durability and a more scale look. Last few mods, I bent my drag link at a slight angle so I could remove the spacer from the knuckle. That spacer adds a lot of stress to the knuckle, by basically acting like a pry bar every time the rig takes a hard hit on the front wheels. With the drag link bent it removes that stress, and will be more reliable over time. Then, I installed a short M3 set screw to the unused holes in the knuckles. These will help stop the knuckles from bending/breaking while tumbling down the hills at speed.

Thanks for sharing this info. we are trying to promote this type of “speed demon” to our crawler community here too
what did you use for a spur and pinion combo?
I am running a 87/20 combo in this rig.
