Action Truck Cap Fxwo Fitment Guide: Precision for Performance

Understanding the Action Truck Cap Fxwo Series

The Action Truck Cap Fxwo series represents a pinnacle in truck cap design and functionality. While specific features can vary by model within the series, Fxwo caps are generally characterized by their:

• Premium Construction: Often utilizing durable fiberglass or aluminum, engineered for strength and longevity.
• Advanced Features: This can include frameless glass rear doors, integrated LED lighting (interior and third brake light), carpeted interiors, secure locking mechanisms, and often, a custom-molded fit for specific truck models.
• Sleek Aesthetics: Designed to complement the lines of modern trucks, enhancing the overall vehicle appearance.
• Weather Resistance: Engineered with robust sealing systems to protect cargo from the elements.

Given these premium attributes, ensuring proper fitment for an Fxwo cap is paramount. A poorly fitted cap can negate many of its benefits, leading to leaks, rattling, compromised security, and even damage to your truck bed or the cap itself.

Why Proper Fitment Matters: The Cornerstone of Cap Performance

The importance of precise fitment cannot be overstated. It is the foundation upon which all other benefits of your Action Fxwo truck cap rest.

1. Optimal Weather Protection: A perfectly sealed cap prevents water, dust, and debris from entering the truck bed, keeping your cargo dry and clean. Gaps, no matter how small, can lead to leaks that damage electronics, tools, or other valuable items.



2. Enhanced Security: A snug fit, combined with robust clamping and locking mechanisms, deters theft. Loose caps can be pried open more easily or may even shift during transit, exposing contents.
3. Reduced Noise and Vibration: A well-fitted cap sits securely on the bed rails, eliminating annoying rattles, squeaks, and wind noise, especially at highway speeds.
4. Improved Fuel Efficiency: While often overlooked, a properly aligned and sealed truck cap can slightly improve aerodynamics, leading to marginal gains in fuel economy by reducing drag. A poorly fitting cap can create turbulence.
5. Aesthetic Appeal: The Fxwo series is designed to look integrated with your truck. A cap that doesn’t sit flush, has noticeable gaps, or is misaligned detracts significantly from your truck’s appearance.
6. Longevity of Cap and Truck: Correct fitment distributes the cap’s weight evenly and prevents undue stress on the bed rails. This minimizes wear and tear on both the cap’s structure and your truck’s finish, preventing scratches, dents, and potential rust spots caused by rubbing.



7. Safety: A cap that shifts or isn’t securely clamped can be a safety hazard, potentially detaching during sudden stops or turns, especially if not correctly installed.

Pre-Fitment Essentials: Gathering Your Truck’s Information

Before you even think about ordering or installing an Action Fxwo cap, you need to precisely identify your truck’s specifications. This information is crucial for selecting the correct Fxwo model designed to fit your specific vehicle.

• Truck Year, Make, and Model: This is the absolute baseline. (e.g., 2023 Ford F-150, 2020 Chevrolet Silverado 1500, 2022 Toyota Tacoma).
• Cab Style: (e.g., Regular Cab, Extended Cab, Crew Cab/Double Cab). While the cab style doesn’t directly impact cap fitment, it’s often part of the complete vehicle identification for ordering.
• Bed Length: This is paramount. Truck beds come in various lengths (e.g., 5.5 ft, 6.5 ft, 8 ft). You’ll need to measure your truck bed’s inside length accurately from the bulkhead (the front of the bed, nearest the cab) to the inside of the tailgate.
• Bed Rail Type: Does your truck have factory bed rail caps (plastic covers over the metal bed rails)? These can sometimes affect how the truck cap clamps or seals, though most Action Fxwo caps are designed to accommodate common factory setups.
• Special Features: Does your truck have a bed liner (drop-in or spray-in)? A factory multi-position tailgate (like Ford’s Pro Access Tailgate or GMC’s MultiPro Tailgate)? These features might require specific cap configurations or minor adjustments for optimal fitment.

The Critical Measurement Process for Fxwo Fitment

Even after identifying your truck’s basic specifications, taking precise measurements of your actual truck bed is highly recommended. This eliminates any ambiguity and accounts for potential variations or aftermarket additions.

1. Bed Length (Inside):
   • Use a reliable tape measure.
   • Measure from the inside of the bulkhead (the front wall of the truck bed, closest to the cab) to the inside of the closed tailgate.
   • Measure along the top edge of the bed rails.
   • Take multiple measurements at different points (center, left, right) to ensure consistency. Note down the exact measurement in feet and inches.
2. Bed Width (Inside):
   • Measure the inside width of the truck bed at two key points:
     • Near the bulkhead: Across the top of the bed rails.
     • Near the tailgate: Across the top of the bed rails.
   • Note down both measurements. While most caps are designed for standard width, knowing these ensures no unexpected surprises.
3. Bed Rail Height:
   • Measure from the very top surface of your truck’s bed rail down to the lowest point of the bed floor. This helps in understanding the internal volume and how the cap will sit.
4. Tailgate Angle/Profile:
   • While not a direct measurement, observe your tailgate’s profile when closed. Some tailgates have a slight curve or specific contour. Fxwo caps are designed to match these contours for a seamless look and seal. If you have an unusual tailgate (e.g., a multi-position one), ensure you communicate this to your Action Cap dealer.

Actionable Insight: Always double-check your measurements. Measure at least twice, or even better, have a second person verify. Even a quarter-inch discrepancy can lead to fitment issues.

The Fxwo Fitment System Explained: Precision Engineering

Action Truck Cap’s Fxwo series isn’t just a generic line of caps; they are typically engineered with truck-specific molds and designs. This means that an Fxwo cap for a Ford F-150 will have a different mold and contour than one for a Ram 1500, even if they share similar bed lengths.

The "Fitment Guide" aspect refers to Action’s internal design and manufacturing process that ensures each Fxwo model aligns perfectly with the unique dimensions and body lines of specific truck years, makes, and models. This includes:

• Custom Molded Base Rails: The bottom edge of the Fxwo cap is precisely molded to match the top surface of your truck’s bed rails, ensuring a flush and secure fit.
• Integrated Sealing Systems: Fxwo caps utilize high-quality bulb seals or foam tape seals pre-applied to the cap’s base. These seals compress against the truck bed rails to create a watertight barrier.
• Model-Specific Clamping Systems: Action provides specific clamps (e.g., J-clamps, C-clamps) designed to securely attach the Fxwo cap to your truck’s bed rails without drilling into the truck body. These clamps are chosen based on the truck’s bed rail design.
• Tailgate Match: The rear door and lower skirt of the Fxwo cap are contoured to seamlessly meet your truck’s tailgate, ensuring a tight seal and integrated appearance.

Step-by-Step Fxwo Fitment & Installation (General Principles)

While professional installation is always recommended for Action Fxwo caps, especially given their premium nature and wiring components, understanding the general principles of fitment and installation is beneficial.

1. Preparation:
   • Clean your truck’s bed rails thoroughly. Remove any dirt, debris, or old adhesive residue. A clean surface is crucial for proper sealing and adhesion.
   • If using additional weather stripping (not pre-applied), ensure it’s positioned correctly on the bed rails according to instructions.
2. Positioning the Cap:
   • With assistance (Fxwo caps are heavy!), carefully lift and center the cap onto your truck’s bed rails.
   • Slowly lower it, ensuring it aligns front-to-back and side-to-side.
   • Tip: Don’t rush this step. Take your time to get the alignment perfect. Look for even overhangs on all sides.
3. Initial Seating and Alignment:
   • Once the cap is resting on the bed rails, gently push down on all corners and edges to ensure the pre-applied seals compress evenly.
   • Check the alignment with your cab. The cap should be parallel to the cab and centered.
   • Verify the fit at the tailgate. The rear door of the cap should close flush with the tailgate, providing a tight seal.
4. Clamping:
   • Install the provided clamps evenly along the bed rails. The number and placement of clamps will be specified in the installation guide.
   • Tighten the clamps gradually, alternating between sides, to apply even pressure. Do not overtighten, as this can damage the cap or bed rails. Snug is sufficient.
   • Practical Advice: Recheck clamp tightness after a few days of driving, as seals may compress further.
5. Wiring (if applicable):
   • Most Fxwo caps come with integrated features like LED interior lights and a third brake light. This requires wiring to your truck’s electrical system.
   • Actionable Insight: If you’re not comfortable with automotive electrical work, this is a prime reason to opt for professional installation. Improper wiring can lead to electrical issues or even fire.
6. Final Inspection:
   • Close and open the rear door multiple times to ensure smooth operation and proper latch engagement.
   • Check all seals for any gaps or uneven compression.
   • Perform a water test (e.g., hose down the cap) to check for leaks before loading valuable cargo.

Common Fitment Challenges & Troubleshooting

Even with careful planning, minor fitment challenges can arise.

• Leaks:
  • Cause: Improperly compressed seals, gaps in the seal, or water ingress from the tailgate area.
  • Solution: Re-tighten clamps evenly. Apply additional silicone sealant or weather stripping in problem areas (especially at the front bulkhead corners and tailgate gaps). Ensure the tailgate seal is intact.
• Cap Not Sitting Level:
  • Cause: Uneven bed rails (common with older trucks or trucks that have seen heavy use), or improper initial positioning.
  • Solution: Use thin shims (e.g., rubber or composite shims) under the cap’s base in low spots to level it out before clamping. Re-position the cap.
• Rattling/Vibration:
  • Cause: Loose clamps, cap not fully seated, or components within the cap (e.g., gas struts, latch mechanisms) needing adjustment.
  • Solution: Check and tighten all clamps. Ensure the cap is fully compressed onto the seals. Lubricate and adjust moving parts as needed.
• Difficulty Closing Rear Door/Latching:
  • Cause: Cap positioned too far forward or backward, or latch mechanism out of adjustment.
  • Solution: Loosen clamps, slightly reposition the cap forward or backward, then re-tighten. Adjust the striker plate or latch mechanism on the cap’s door.

Maintenance for Optimal Fitment & Longevity

Once your Action Fxwo cap is perfectly fitted, a little ongoing maintenance will ensure it remains so for years to come.

• Regular Cleaning: Wash the cap regularly with mild soap and water to prevent dirt and grime buildup that can affect seals.
• Seal Inspection: Periodically check all rubber and foam seals for cracks, tears, or compression set. Replace damaged seals promptly.
• Clamp Check: Every few months, re-check the tightness of all mounting clamps. Vibrations from driving can sometimes loosen them.
• Hinge and Latch Lubrication: Lubricate hinges, gas struts, and latch mechanisms with a silicone-based spray or grease to ensure smooth operation and prevent wear.
• Drainage Channels: Ensure any integrated drainage channels or weep holes are clear of debris.
