This is our “MADE IN AMERICA” direct replacement viscous coupler for the 2002 to 2010 Ford Explorer AWD, Lincoln Aviator AWD, Mercury Mountaineer AWD with the BW 44-10 transfer case. Our coupler is made from US certified 6061 T6 aluminum and the splined center hub is made with high carbon US steel. VERY TOUGH! Nothing needs to be modified or adapted to make our coupler fit, each one is hand fitted on a OE shaft and tested before it leaves the shop! You can`t buy a better coupler anywhere. As you can see our coupler is smooth and has no ribs, OE couplers are die cast and need the ribs for strength, they are not for cooling.

AWD and fulltime 4WD vehicles need extra attention to tire size. All tires must measure NO MORE than 3/16″ circumference difference. More than this will damage the coupling Unit. Don’t forget to measure your tires.
