The +16.7 axles are awesome! It's nice having the ability to build a super comp without spending $500+ on axles. Very pleased with these and will be buying more.
I’m liking the axles, make my rig look like a 1/10 scale, it’s a big difference between the meus mullet axles with 5mm spacers
These are sic!! I have no plan. Just had to have them. Fun times!
Love these. However the sharp edge on the bottom of the front pumpkin has to be sanded down and polished to prevent hanging. After that it slides over the rocks like butta.
