Instructions
NOTE: The photos included show work done on a frame that has been removed from the
body. Although this looks somewhat different than work done on a frame attached to the
truck body, the steps will remain the same.

STEP 1: Remove the truck bed, safely raise the vehicle off the ground, and suitably
support the vehicle. NOTE: CONSULT THE VEHICLE'S OWNER'S MANUAL OR SHOP
MANUAL TO DETERMINE THE PROPER WAY OF RAISING AND LOWERING YOUR VEHICLE.

STEP 2: Using a cutting wheel, cut around
the top and sides of the ends of the crossbar
on the frame, on both sides of the frame.
NOTE: Do not fully cut and remove the
crossbar yet.

STEP 3: Before completely removing the
crossbar, mark off where the center of the
tube goes with a permanent marker, to
accurately place the replacement tube later.

STEP 4: Using a cutting wheel, finish cutting
around the bottom and inside of the ends of
the crossbar on the frame, on both sides of
the frame. Once complete, the cut will go up
and over the tube on the outside and inside
of the frame, on both sides of the frame.
NOTE: Do not cut the frame completely in
half (note that the top of the frame is not cut
in the photos). Make sure the vehicle frame
is properly supported, because the frame
will want to twist or bend when the crossmember is removed.

STEP 5: Once the cuts are complete, remove
the crossbar from the frame.

STEP 6: Place the replacement crossbar
in place of the removed one. Hold the
replacement crossbar in place to the frame
with c-clamps or vice grips. Then, using a
permanent marker, mark off the section
of the frame around where the crossbar
attaches to the frame (on both sides
of the frame).

STEP 7: Remove the replacement crossbar
and the c-clamps or vice grips. Then, using
a handheld torch and paint scraper, clean
down to the bare metal where the crossbar
will attach to the frame, on both sides of the
frame, for a proper and strong weld.

STEP 8: If necessary, using a flap wheel disc,
sand the outside of the frame to clean
for welding, on both sides of the frame.

STEP 9: Using c-clamps or vice grips, place
the outer plates to the outside of the frame,
on both sides of the frame.

STEP 10: Using a welding torch, weld the
outer plate to the outside of the frame on
both sides of the crossbar.

STEP 11: Hold the tube and inner plates
in place on both sides of the frame. Then,
using a permanent marker, mark off the
section of the frame around the inner plates
(on both sides of the frame), so you can
clean the frame underneath the inner plates
down to the bare metal.

STEP 12: Remove the tube and inner plates
from the frame. Then, using a flap wheel
disc, sand the inside of the frame to clean
for welding, on both sides of the frame.

STEP 13: When you are finished, the inside
of the frame on both sides should be clean
as shown.

STEP 14: Replace the inner plate and tube,
and hold in place using c-clamps
or vice grips.

STEP 15: Using a welding torch, weld the
inner plate to the inside of the frame, on
both sides of the frame. Then, weld around
the tube to the inner and outer plates, on
both sides of the frame.

STEP 16: When finished, the weld on the
inner and outer plates and around the tube
should look like the photos shown.

STEP 17: Once the tube is in place, attach
the included exhaust hanger in the same
location as the OE.

STEP 18: Be sure to paint all bare metal
surfaces to prevent any rust or corrosion.

STEP 19: Safely lower the vehicle. NOTE: CONSULT THE VEHICLE'S OWNER'S MANUAL
OR SHOP MANUAL TO DETERMINE THE PROPER WAY OF RAISING AND LOWERING
YOUR VEHICLE.
