Will this tailgate support fit my Nissan Frontier?

• Position: rear left, driver side
• Reference part number: SG325900EZ for cross-checking

How does installing this shock improve tailgate operation?

The replaceable gas strut controls the tailgate’s motion, slowing the descent and assisting lift for smoother, safer operation. That reduces stress on latch hardware and prevents sudden slams that can damage the tailgate or cause injury.

• Smoother opening and closing movement
• Reduced effort to lift the tailgate
• Helps prevent abrupt drops and hardware wear
• Preserves original tailgate alignment and operation

What are the key specs and installation notes?

The A-Premium kit is built to match original equipment dimensions and mounting orientation so installation uses existing brackets and fasteners. No welding or bracket modification is typically required—basic hand tools are usually sufficient.

• Extended length (fully extended): 18 inches
• Location: rear left / driver side replacement
• OE-style mounting for direct-fit installation
• Inspect ball studs and brackets; replace hardware if corroded

How long will this replacement last and when should I replace it?

Service life depends on use, climate, and exposure to road elements; replace the strut if the tailgate sags, drops suddenly, or requires excessive force to open. Regular inspection for leaks, weak rebound, or damaged fittings helps catch failures early.

• Replace if tailgate no longer holds open or drops quickly
• Check for gas leaks and worn ball-socket ends
• Allow replacement when weather or salt increases corrosion risk
