5. Setup and Installation
The CR-Z Chase Rack features a 5-piece modular design that bolts together for a clean and secure installation. Due to the nature of this product and the need for precise fitment and electrical connections for the integrated lighting, professional installation is highly recommended.
5.1 Pre-Installation Steps
- Unpack Components: Carefully remove all parts from the packaging and verify against the parts list.
- Inspect for Damage: Check all components for any shipping damage. Do not proceed with installation if damage is found; contact your vendor immediately.
- Gather Tools: Ensure you have all necessary tools for installation (e.g., wrenches, sockets, measuring tape, wire cutters/strippers, electrical tape).
- Vehicle Preparation: Clean the truck bed rails where the chase rack will be mounted. Ensure the area is free of debris and obstructions.
5.2 Assembly and Mounting
The modular components are designed to bolt together. Refer to the included diagrams (if provided separately) for specific assembly order. The rack is adjustable to accommodate various mid-size truck bed widths.

- Assemble Main Sections: Connect the primary modular sections of the chase rack using the provided hardware. Do not fully tighten bolts at this stage to allow for adjustment.
- Position on Truck Bed: Carefully place the assembled rack onto the truck bed rails.
- Adjust for Fitment: Adjust the rack's width to match your truck bed, ensuring a snug and secure fit. Refer to Figure 5.1 for extension details.
- Secure Mounting: Once properly positioned, use the mounting hardware to securely fasten the chase rack to the truck bed rails. Tighten all bolts evenly and firmly.
5.3 Electrical Connection for Lighting
The auxiliary LED lights and amber side marker lights require electrical connection to your vehicle's power system. This typically involves tapping into existing wiring for running lights or a dedicated auxiliary circuit.
- Identify appropriate power sources for the LED lights and amber markers.
- Route wiring safely, away from moving parts or heat sources, and secure with zip ties or clips.
- Make all electrical connections using proper connectors (e.g., crimp connectors, solder) and insulate them with electrical tape or heat shrink tubing.
- Test all lights before finalizing the installation.


6. Operation
Once installed, the Armordillo CR-Z Chase Rack operates passively as a structural and aesthetic enhancement. The integrated lighting components require manual activation via your vehicle's electrical system.
- Auxiliary LED Lights: These lights are typically wired to a switch in the vehicle's cabin, allowing them to be turned on or off independently. Consult your installer or vehicle's manual for specific switch operation.
- Amber Side Marker Lights: These lights are generally wired to activate with your vehicle's running lights or headlights, providing additional side visibility.
7. Maintenance
Regular maintenance will ensure the longevity and appearance of your Armordillo CR-Z Chase Rack.
- Cleaning: Wash the chase rack regularly with mild automotive soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the powder coat finish.
- Inspection: Periodically inspect all mounting hardware for tightness. Check for any signs of rust, corrosion, or damage to the steel structure or powder coating.
- Electrical Connections: Ensure all wiring and electrical connections for the lights remain secure and free from corrosion or damage.
- Light Functionality: Periodically test the auxiliary LED lights and amber side marker lights to ensure they are functioning correctly.
8. Troubleshooting
If you encounter issues with your chase rack, consider the following common troubleshooting steps:
- Loose Rack: If the rack feels loose, re-check and tighten all mounting bolts. Ensure the rack is properly adjusted to the truck bed width.
- Lights Not Working:
- Check all electrical connections for looseness or corrosion.
- Verify that the fuse for the circuit is intact.
- Ensure the switch (if applicable) is in the "ON" position.
- Inspect wiring for any cuts or pinches.
- Unusual Noises: Inspect all components for proper fitment and ensure no parts are rubbing against the truck or other accessories. Tighten any loose hardware.
