Works good, gives you a lot of traction, which helps with wheelies and drifting. I have this on my rustler 4x4 and I drive it on dirt and gravel and this helps a ton. I did break a rear driveshaft minutes after installing this because with the differential being locked the tires can’t spin at different speeds so when you’re turning the force is being put on the driveshafts.
