TGR11000 Installation Instructions
• Initial fitment of the floor mount brackets must be done under the carpet. Final installation can
be done under or over the carpet.
• Use Anti-Seize on all fasteners that are threaded into stainless clamps or brackets.
• Install all bars before final tightening.
• Always tighten the tab side of the clamp first.
• Torque all 3/8” fasteners to 45 ft-lbs and all 1/2” fasteners to 75 ft-lbs.
• Make sure the clamp is exactly where you want it before tightening as the clamp may scratch
the tubing.
• Watch for fuel and brake lines when drilling holes through the floor pan.
1. The first bracket to be mounted
needs to be the main hoop floor
mount. It should be mounted 2 3/8”
behind the rocker panel seam.
2. The wire trough cover needs to be
notched to allow clearance for the
hoop mount. Mark the bracket
location on the wire trough cover.
Remove cover and cut the marked
section out.
3. Using the bracket as a template
drill four 3/8” holes in the floor pan.
Fasten the upper holes in the bracket
to the quarter panel structure with two
3/8” x 1 ¼ bolts, flat washers and
Nylok nuts. A reinforcement plate
will be installed inside the quarter
panel.
4. Secure the lower portion of the
bracket to the floor pan with two 3/8” x
1 ¼” bolts, flat washers and Nylok
nuts. Another reinforcement plate will
be installed under the car. It will also
meet up with the body seam.
5. Two more 3/8” holes must be
drilled through the body seam. 3/8” x
1 ¼” bolts, flat washers and Nylok
nuts will be used here.
6. Fasten the main hoop to the
mounts using 3/8” x 1” Socket Head
Cap Screws and lock washers.
7. In order to keep the “T” in the
casting facing up, and the bolts facing
the correct direction, there are two
different direction clamps. Be very
careful as to which clamp halves you
are bolting together. Refer to the
image on page 6 for clamp locations.
8. A correctly assembled clamp
should look like the one in the picture
shown to the left; there should be a
gap on one side for the tab to slide
into.
9. The next bar to be installed is the
package tray bar.
10. Before installing the bar, use the
template on page 7 to drill four holes
in the top of the package tray for the
bar flange to bolt to.
11. Fasten the clamp to the main
hoop with the tab facing rearward.
Use clamp D on the driver side and
clamp P on the passenger side.
12. The other end of the bar will
attach to the top of the package tray.
Drop four 3/8” x 1 ¼” bolts with flat
washers down through the package
tray.
13. The lip around this opening in the
package tray will interfere with the
trunk bar bracket. The lip can be cut
with a die grinder and flattened with a
pair of pliers.
14. Bolt the trunk bar up to the
package tray bar with 3/8” Nylok nuts
and flat washers.
15. Using the bracket as a template
drill two 3/8” holes through the vertical
surface of the package tray.
16. Place the reinforcement plate
inside the car and fasten with two 3/8”
x 1 ¼” bolts and Nylok nuts.
17. Using the trunk bar plate as a
template, drill six 3/8 holes through
the trunk floor. Drop six 3/8” x 1 ¼”
bolts with flat washers down through
the holes.
18. Place the reinforcement plates up
against the bottom of the trunk pan
(one on each side of the frame rail)
and secure with 3/8” Nylok nuts and
flat washers.
Note: The plate with 4 holes will be
installed to the outside of the rail.
