Fender Modification for clearance of 285/70/R17 Tires mounted on a
17x8 wheel with 4.5” of backspacing.
1. Position truck on a flat surface and lift
vehicle by the frame so that the front
wheels are off the ground using a floor
jack and jack stands or a (2) two post
lift if available.
2. Remove (2) OE screws and (2) plastic
push pin retainers located on the bot-
tom of the front fender rear plastic liner.
3. Using a cut of wheel or another suit-
able tool, trim the fenders along the cut
line in picture A.
4. Using a plastic or rubber mallet,
CAREFULLY bend the inside of the
fender lip back to provide tire clear-
ance. Use the measurement and dot-
ted line in picture B as a guide line for
bending. See Picture B.
NOTE: The dotted line is only to
be used as a guide line and the
fenders may require additional
modification.
IMPORTANT!: Make sure the bot-
tom fender bolt is tight prior to flat-
tening the inside fender to avoid
movement.
IMPORTANT!: Pay close atten-
tion to the spacing between the
fenders and the front doors prior to
flattening the inner fender. Make
sure you haven’t reduced this spac-
ing, while flattening out the inner
fender, or the doors will make con-
tact with the fenders when opened.
5. Mask any painted areas of the fender.
Prep the trimmed or modified areas for
paint and using a paint primer, prime
the prepared area and let dry. Under-
coat the primed area of the fender. Let
undercoating dry properly before re-
moving the masking and reinstalling
the plastic inner fender liner back onto
the lower portion of the fender using
the previously removed OE hardware.
