Choosing the Right Chevrolet Colorado Tailgate Assist: Key Factors to Consider
Damping Performance
How smoothly the tailgate lowers is the core function of any tailgate assist. Effective damping controls the tailgate's descent speed and prevents abrupt impacts at the bottom. For the Chevrolet Colorado, look for kits that provide a controlled, steady motion from full open to closed without letting the tailgate bounce or drift.
Variable damping or tuneable resistance can help if you often carry different loads or prefer a firmer or softer feel. Poor damping not only compromises usability but increases stress on the latch and hinges over time, raising the risk of misalignment or premature wear.
Vehicle-Specific Fitment
Fitment matters because mounting points and tailgate geometry differ across trucks. A kit designed or confirmed for the Chevrolet Colorado will align with factory attachment locations and avoid interference with bed liners, cargo tie-downs, or factory wiring.
Double-check whether the kit supports the Colorado bed length and any common bed accessories. Choosing a vehicle-specific solution minimizes modification, reduces installation time, and limits the chance of incorrect operation due to improper geometry.
Mounting Hardware and Installation Complexity
Installation ranges from simple bolt-on kits that use existing holes to kits that require drilling or removal of trim pieces. Consider how comfortable you are with basic hand tools and whether you have access to lifts or help for holding the tailgate during installation.
Kits that include clear hardware, grade-appropriate fasteners, and comprehensive instructions are easier to install correctly. If hardware relies on clamp mounts or adhesives, evaluate their long-term durability compared with bolted brackets. Time and tool investment are real ownership costs that influence the final choice.
Durability and Corrosion Resistance
Tailgate assists operate in a harsh environment exposed to water, road salt, and debris. Materials and finishes determine how long the gas spring and mounting brackets will last without seizing or corroding.
Look for sealed gas springs, stainless or zinc-plated hardware, and protective coatings on brackets. Robust construction reduces the chance of failure, which can cause sudden loss of damping or damage to the tailgate. Consider local climate and expected exposure when weighing durability features.
Maintenance and Serviceability
Over time, gas springs can lose pressure and fasteners can loosen. Select a product with replaceable components or easy access to service parts. Some kits allow replacement of just the gas strut or damper rather than the entire assembly.
Clear warranty terms and the availability of replacement fasteners or struts are practical benefits. Also consider how easy it is to inspect and tighten mounting points without removing trim or cargo; simpler maintenance reduces long-term ownership hassle.
Operational Convenience and Safety
A good tailgate assist should make daily use safer and more convenient. That includes allowing one-handed lowering, preventing accidental slams when children or pets are nearby, and reducing the risk of tailgate-related injuries.
Check how the assist interacts with the tailgate latch and whether it changes the required force to close. Some systems alter the closing feel or require a firmer push at the last few degrees. Weigh convenience against any necessary changes to normal tailgate operation.
Understanding How Tailgate Assists Work
Tailgate assists use gas springs or dampers to slow the tailgate as it drops, converting kinetic energy into controlled resistance. The basic components are a strut and mounting brackets that link the tailgate to the bed or hinge area. When you open the tailgate, the strut stores energy and then releases it as a controlled lowering action.
Knowing whether a kit uses a single strut, dual struts, or a hydraulic damper helps set expectations for performance. Single strut designs are compact and often easier to install, while dual-strut setups can offer more even force distribution across the tailgate. Hydraulic dampers provide smooth action but may be bulkier.
- Gas strut: sealed, pressure-based support and damping
- Hydraulic damper: fluid-based slowing for steady descent
- Single vs dual strut: tradeoff between simplicity and balanced force
Common Installation Steps for the Colorado
Most installations follow a similar sequence: support the tailgate, remove any trim obstructing mounting points, attach brackets to the bed and tailgate, and fasten the damper or strut. Torque specifications and final alignment are important to ensure smooth operation and to prevent undue stress on mounting points.
Expect to allocate around an hour for a straightforward bolt-on kit if you are comfortable with basic tools. Kits requiring drilling or removal of inner tailgate panels will take longer and may be better suited to a professional or a well-equipped DIYer.
- Always start by securely supporting the open tailgate before working underneath
- Follow the kit instructions for bracket orientation to avoid binding
- Check operation several times after installation and retighten fasteners
How Climate and Use Affect Choice
If you frequently drive on salted roads or in wet climates, prioritize corrosion-resistant finishes and fully sealed struts. Frequent heavy loads or regular one-handed operation favors higher-duty components with thicker brackets and reinforced mounting points.
For occasional light use, a simple support kit may be sufficient. For work or heavy recreational use, expect to choose a more robust unit designed for higher cycle counts and tougher conditions.
- Cold weather can stiffen damping; choose kits rated for a broad temperature range
- High-mileage or heavy-use trucks benefit from upgraded brackets and sealed components
- Consider bed covers, liners, and accessories that might interfere with bracket placement
Compatibility With Bed Accessories
Bed liners, protective caps, or tonneau hardware can obstruct mounting locations or change bracket fit. Before selecting a kit, inspect the tailgate hinge area and inside bed rails to see if any add-ons will interfere.
Some kits include alternative brackets or spacers to clear common accessories. If your Colorado has a spray-in liner or bed rail caps, verify whether trimming or alternate hardware is necessary to maintain proper alignment and function.
- Measure clearance between inner tailgate skin and bed lining before purchase
- Check for interference with pickup bed lighting or wiring routed near the hinge
- Look for kits that document compatibility with common bed liners
Safety Tips During Installation and Use
Always support the tailgate securely while installing an assist to prevent sudden drops. Use a prop or have a helper hold the tailgate in the open position when fitting brackets or struts. Wear eye protection when drilling or working under the tailgate.
After installation, cycle the tailgate several times with a clear zone to confirm smooth operation and to ensure the assist does not interfere with the latch. Periodically check fasteners for tightness and inspect the strut for signs of leakage or damage.
- Never rely solely on a new damper while testing; always keep hands clear of hinge areas
- Keep children and pets clear during installation and initial testing
- If you feel unusual binding or hear metal-on-metal contact, stop and inspect the mounting
