INSTALLATION TIPS

• The “M” logo orientation should be on the right when looking at the shield from below.
• Torque specs on tamper-proof screws are 37-72 inch lbs.
• Highly recommend replacing exhaust hangers to reduce noise and vibration.

STEP 1
Remove the under panel. Remove the three (3) nuts holding the under panel by using a 10mm socket and driver. Refer to image A.

STEP 2
Mark holes for drilling. Temporarily place the Cat Shield onto the vehicle using the three (3) studs as a guide and hand tighten the shield with 3 new M6 flange nuts (provided) onto the studs. Locate the 3 holes along each side of the Cat Shield and make a mark inside all 6 holes. Optional: use a center punch tool at each of these markings for easier drilling. Refer to image B for locations.

STEP 3
Drill 6 holes for the rivet nut. Remove the front 3 nuts used to hold the Cat Shield. Using the drill bit (with no pilot bit), drill the marked locations to make 6 holes in the vehicle frame.

STEP 4
Install rivet nuts. Using a rivet nut tool, install the six (6) rivet nuts to the recently drilled holes. Please watch an instructional video if you have never used a rivet nut tool before.

STEP 5
Install Cat Shield. Place the Cat Shield onto the three (3) front studs. Tighten the Cat Shield to the three front studs using the three M6 flange nuts provided.

STEP 6
Install tamper-proof screws. Using the six (6) provided tamper-proof screws and hardware, fasten the rest of the shield to the vehicle. For each screw, install the fender washer, lock washer, and tamper-proof screw in the order shown below. Use the provided tamper-proof bit to tighten the tamper- proof screws. Refer to image C.

STEP 7
Tighten all nuts and screws. Check each nut and screw to ensure the shield is completely secured to the vehicle.

STEP 8
Apply Cat Shield sticker (optional). Place the sticker on the vehicle to warn thieves that the vehicle is protected by Cat Shield! Recommended placement: Rear lift gate window.
