Be sure that the JFlaps (fig. 1 ) and the fender edge (fig.3) where they will be mounted, are clean and dry. Beginning at the bottom of the JFlap, position the u channel (fig.2) over the fender edge and carefully push it on along its entire length (figA). After checking for good alignment on the vehicle, push firmly along the u channels entire length for secure fit.

If the u channel feels as though it fits too tightly or loosely the width of the u channel may be adjusted by hand, by removing the JFlap and gently widening or squeezing the u channel for better fit.

Removal: Beginning at the bottom of the JFlap, gently pull the u channel off the fender flange. Clean the JFlaps using mild soap and water, rinse and dry thoroughly. For more information please visit:
