DEE ZEE Tailgate Assist for 2015–2022 Chevrolet Colorado & GMC Canyon - DZ43105, No-Drill Quiet Controlled Drop

DEE ZEE DZ43105 is a vehicle-specific tailgate assist that controls the downward motion of your 2015–2022 Chevrolet Colorado or GMC Canyon tailgate for safer, quieter operation.

This tailgate assist is engineered to replace or upgrade the factory shock that controls the tailgate’s descent, delivering a smooth, controlled drop instead of a sudden slam. Designed to work with the original cables and hinge hardware, the DZ43105 is built to fit the 2015–2022 Colorado and Canyon exactly, and it includes all mounting parts for a straightforward, no-drill installation. Dee Zee updated the nutsert so it arrives pre-treated with locking compound, eliminating messy adhesives during install.

How does the DZ43105 make tailgate use easier?

The DZ43105 reduces the force needed to lower the tailgate and prevents free-fall, which means you can open the tailgate with one hand and avoid loud impacts. The unit cushions the tailgate as it descends, protecting the hinge and factory cables from sudden stress and wear. That smoother motion also reduces noise and makes it safer around children and pets.

• Enables one-handed tailgate release and quiet closing
• Prevents sudden slamming that stresses cables and hinges
• Delivers consistent, controlled descent every time

Will installing the tailgate assist harm my truck or require drilling?

No drilling is needed; the kit is tailored to the specified model years and includes all vehicle-specific hardware. The updated nutsert comes pre-applied with locking compound to simplify assembly and avoid handling adhesives. Because it mounts with factory attachment points and shares load with the original cables, it won’t interfere with OEM components when installed correctly.

• Model-specific hardware included for 2015–2022 Colorado/Canyon
• No-drill installation using existing mounting locations
• Pre-treated nutsert removes need for separate locking adhesive

How durable is the Dee Zee tailgate assist for daily use?

The DZ43105 is built to withstand repeated opening and closing under normal truck use. Components are tested for endurance and corrosion resistance to perform reliably outdoors and in changing weather. Using this assist reduces shock loads on factory cables and hinges, which can extend the functional life of those parts.

• Constructed and tested for frequent, real-world operation
• Designed to resist corrosion and stand up to weather exposure
• Lessens wear on cables and hinge points by controlling descent

What comes in the kit and how long does installation take?

The package contains the tailgate assist assembly, model-specific mounting hardware, the improved pre-treated nutsert, and clear instructions. Most owners can complete the install in minutes with common hand tools; professional installation is optional if you prefer. No body modifications or extra parts are required beyond what’s in the box.

• Complete kit: assist unit, hardware, pre-treated nutsert, instructions
• Typical install time: minutes for a DIYer with basic tools
• No extra adhesives or drilling necessary for proper fitment

Who is this for? The DEE ZEE DZ43105 tailgate assist is ideal for Colorado and Canyon owners from model years 2015 through 2022 who want a quieter, safer tailgate experience without altering their truck. It suits daily drivers, families, and anyone who frequently loads cargo or uses the tailgate as a workspace and prefers a controlled, consistent drop. If you want an easy-to-install, vehicle-specific upgrade that reduces stress on factory parts and improves usability, this kit is a practical choice.
