Thanks Crash, I'm glad you liked them, they are pretty impressive when you see them up close. I can report that I put these in some nasty binds today that would have surely broke the old XR gears, these took the abuse no problem, no broke gears or cvd's. We comped on wet rip-rap so lots of tire swallowing holes to try and get unstuck from so I figured I would do a durability test and see what I can expect out of these, I'm impressed myself! For anyone wondering, they are a lot like berg axles in how they drive and hold up to abuse, with a bit extra ground clearance and the fact you don't need to buy extra stuff to make these work. They truly are a comp axle you can buy and bolt in with no worries of them holding up. Great job RC4WD!"thumbsup"
