Why Fabco axles are built the way they are
For medium duty and heavy duty 4x4 and 6x6 trucks, Fabco supplies a complete driveline: front drive steer axles matched to its own transfer cases. The axles are designed for commercial, military and specialty applications, and their modular design lets one family cover many specifications. They are built for long service life with less frequent, less labor intensive maintenance, and they hold up in the toughest applications.
Because the axle and transfer case are designed to work as a pair, it pays to look at both when one fails. We carry Fabco transfer case parts and rebuilt transfer cases as well.
