Drop brackets are used on mountain sleds and the purpose of them is to raise the ride height of your sled. It does this by lifting the tunnel of your sled higher off the track, this allows you to go through the powder snow much easier, and it will also change the attack angle of your sled, putting more pressure on your front ski's which some people prefer for hill climbing. You can adjust your limiter strap and front suspension if you do not like the additional ski pressure. Please note that if you want a colored axle it will be anodized, not powder coated like our wheels. The colors will be close, just not an exact match.
