Step-by-step instructions for installing a low-profile soft roll-up tonneau cover on your Ford Ranger. Includes tips for the Armordillo CoveRex SR Series.
Quick answer
Installing a soft roll-up tonneau cover like the Armordillo CoveRex SR Series is a straightforward no-drill process that takes about 30 minutes with basic hand tools.
Before You Start: What You'll Need
Make sure you have a clean, dry truck bed and a helper for lifting the cover. The Armordillo CoveRex SR Series includes all necessary hardware, so you won't need to buy extra brackets or drill into your truck's bed rails. Common tools required are a Phillips screwdriver, a 10mm socket or wrench, and a tape measure.
Understanding the No-Drill Advantage
The CoveRex SR Series uses a clamp-on rail system that attaches to the top edge of your truck's bed sides without any drilling. This preserves your truck's resale value and avoids potential rust points. The system is designed specifically for 6-foot beds, like those on the 2019-2023 Ford Ranger.
Step-by-Step Installation
- 1. Assemble the Side Rails: Slide the front and rear rail sections together and tighten the connecting bolts finger-tight. Do not fully tighten yet. Common mistake: over-tightening before alignment can cause the rail to bind and not sit flush on the bed rail.
- 2. Attach the Clamps: Position the clamps over the top edge of your truck's bed sides, spacing them evenly according to the instructions. Tighten the clamp bolts to secure the rails. Checkpoint: ensure the clamps are centered on the bed rail and not interfering with any existing tie-downs or stake pockets.
- 3. Install the Front Header Bar: Place the front header bar against the front of the bed, aligning it with the side rails. Secure it using the provided brackets and bolts. Common mistake: forgetting to leave a small gap (about 1/8 inch) between the header bar and the cab to avoid rubbing on painted surfaces.
- 4. Roll Out the Cover: Unroll the vinyl cover over the rails, starting from the front header bar. Make sure the cover is centered and the tension adjustment straps are accessible. Checkpoint: on a warm day the vinyl will be more pliable; if it's cold, let the cover warm up indoors for 30 minutes first.
- 5. Secure the Cover to the Rails: Snap or slide the cover's edge into the rail channels, working from front to back. Apply even pressure to avoid wrinkles. Common mistake: pulling the cover too tight at the front can cause it to pull away from the rear rail when rolled up.
- 6. Tension and Test: Adjust the tension straps at the rear of the cover to remove any sag. Roll and unroll the cover once to verify smooth operation and proper fit. Final check: the cover should be taut but not drum-tight; if it's too loose, it will flap at highway speeds.
