Hands down the best pure comp crawler axle available for the money. I've been abusing mine for 3 years without issue. With all the fine tuning you can do with link and shock placement these cant be beat!

Build to comp
Bully 2 is the ''new'' name in comp crawler axles... They are built to last... Very strong yet not too heavy... Great steering angle out-of-the-box, they don't need many upgrades to be reliable... Very easy to work on!

A great Axel to start your crawler build with. It is "race ready" out of the Box. I have used an abused mine for some years now and the only thing I did to them was to replase the bearings and add some grease. The bearings was not broken, it was a "just in case" fix :-)

I run this axle for 3 seasons now wihout problems! It´s very very stable and you have many options to set your links and shocks. I run many lipos and had some hard comps with it, but never had an issue, so for me it´s a perfect choice!
