You can count on RPM to hold up to the rigors of high horsepower required for interference engines. 1998 For Ford Contour 4-Cyl. 2.0 L 1999 For Ford Contour 4-Cyl. 2.0 L 2000 For Ford Contour 4-Cyl.
Doesn't get much better than these for normal vehicles. They have saved my contact engines more than once, when the tensioner/idlers have frozen/failed. Normal belts would have worn through and broke causing complete destruction of an engine.
They are worth the extra 50 bucks for insurance if nothing else.
