DEE ZEE Tailgate Assist gas-strut kit for 2015–2022 Chevrolet Colorado / GMC Canyon — no-drill, one-handed drop control

DEE ZEE DZ43105 Tailgate Assist is a vehicle-specific gas-strut kit that controls and softens the drop of the tailgate on 2015–2022 Colorado and Canyon trucks.

If your truck’s tailgate slams when lowered or takes two hands to control, this Dee Zee tailgate assist provides a smooth, damped descent and single-hand release. Designed for the 2015–2022 Chevrolet Colorado and GMC Canyon, the kit integrates with factory cables and hardware for a clean fit. Installation requires no drilling, and Dee Zee supplies all model-specific parts so the project can be completed in minutes with basic hand tools.

How does this tailgate assist make lowering the tailgate easier?

The DZ43105 uses a gas strut that slows and controls the tailgate’s descent so it won’t free-fall or slam. That allows one-handed operation and reduces the effort needed to guide the tailgate into position. The result is quieter daily use and less jarring for cargo and passengers when loading or unloading.

• Gas-assisted dampening for a controlled drop
• One-handed release possible without sudden impact
• Reduces loud bangs that draw attention or startle kids

Will installation damage my truck or require drilling?

No drilling is necessary—this kit is built to mount to the existing factory points on Colorado and Canyon models. Dee Zee supplies vehicle-specific brackets, fasteners and the improved nutsert pre-treated with thread-lock for a secure fit without mess. If you can use simple hand tools, you can complete the install quickly and safely.

• Vehicle-specific hardware for 2015–2022 Colorado/Canyon
• Pre-applied locktite on the nutsert—no blue glue bottle needed
• No drilling, no body modifications required

How does the tailgate assist affect hinge and cable wear?

By preventing the tailgate from free-falling, the DZ43105 reduces shock transmitted through the hinge and factory cables. That softer stop lowers stress on those components over time, which can extend their service life and keep the tailgate operating smoothly. The kit works alongside factory cables rather than replacing them.

• Less impact force on hinge and cable attachment points
• Works in conjunction with factory cables—no replacement required
• Durable components tested for frequent use

What improvements are included in this updated Dee Zee kit?

The latest DZ43105 version includes an upgraded nutsert that arrives pre-treated with thread-lock, removing the need to handle liquid locktite during installation. Dee Zee also ensures fitment is customized for each model year so brackets and fasteners align precisely. The design is tested for repeated use and comes with all mounting hardware necessary for a clean, factory-like install.

• Improved nutsert with factory-applied locktite—clean and simple install
• All-year, make, and model-specific parts included
• Tested to handle heavy, repeated use without failure

Who is this for? The DEE ZEE DZ43105 Tailgate Assist is ideal for Colorado and Canyon owners who want a safer, quieter, and easier tailgate operation—especially those who load cargo frequently, work from their truck bed, or have children and want to avoid sudden slams. It’s also a good choice for owners who prefer a no-drill, reversible upgrade that preserves factory cables and maintains a clean, OEM appearance.
