HXSKJMX Tailgate Assist for 2007–2019 Chevy Silverado & GMC Sierra 1500/2500/3500HD — Reinforced 50+ lb Gas Strut, No-Drill Fit

HXSKJMX Tailgate Assist is a direct-fit gas strut kit that controls and cushions the opening and closing of 2007–2019 Chevy Silverado and 2007–2019 GMC Sierra 1500/2500/3500HD tailgates.

If your pickup tailgate slams, drops too fast, or feels unsafe when lowering heavy loads, this replacement tailgate assist provides a factory-style fit with reinforced components to manage heavier HD tailgates. The kit arrives with pre-assembled hardware so you can install it quickly without drilling, and the calibrated dampening helps prevent sudden drops that can damage cargo or pinch fingers.

How does this tailgate assist improve everyday use?

It replaces worn or missing OEM shocks with a reinforced gas strut designed to slow and smooth the tailgate descent. That controlled movement reduces impact on the gate, load, and people using it. The result is a safer, more reliable tailgate motion every time.

• Reinforced gas strut rated for 50+ lbs to handle heavy HD tailgates.
• Patented dampening action prevents sudden drops and slamming.
• Direct-replacement fit keeps factory geometry and function.
