KALUJ Rear Tailgate Lift Supports for Kia Sorento 2011-2014 — Pair, 610N Nitrogen Gas Struts

KALUJ rear tailgate lift supports are a direct-fit replacement set of two gas struts designed to restore smooth, controlled opening and hold for the Kia Sorento 2011–2014 hatch.

If your Sorento’s rear hatch sags, feels heavy to lift, or drops unexpectedly, worn lift struts are often the cause. These KALUJ replacement tailgate lift supports are engineered to match OEM dimensions and performance so you can regain original hinge support and safe hatch operation without expensive dealer parts. Built with high-strength steel, nitrogen charge technology and reinforced connectors, this pair is tuned for reliable, all-weather performance.

How do these struts match my Kia Sorento’s original equipment?

These KALUJ lift supports are manufactured to the same specifications as the factory parts so installation and motion feel are consistent with OEM behavior. They fit the 2011–2014 Sorento across trims and replace the common OE part numbers used on those model years.

• Exact fit for Kia Sorento 2011, 2012, 2013, 2014 (Base, LX, EX, SX, Limited)
• Direct replacement for OE numbers: 81771-1U000, 817711U000, 31771-1U000, 317711U000, and equivalents
• Extended length: 479 mm; Stroke length: 171 mm; Rated force: 610 N

What performance can I expect day-to-day?

The struts use a high-pressure nitrogen gas charge and an integrated dynamic cushioning system for steady lifting and soft stops. That combination minimizes sudden slams and reduces stress on the hatch hinges, making opening and closing predictable and safer.

• Consistent 610 N lifting force for reliable support
• Dynamic cushioning prevents violent snapping at full extension
• Smooth piston action from micro-polished chrome rod

Are these built to last in different climates and conditions?

Durability is addressed through materials and protective finishes so the struts handle heat, cold and road exposure without premature corrosion or binding. Reinforced ABS ball sockets and electro-coated steel tubing extend service life and maintain secure connection to the hatch fittings.

• High-strength precision steel tube with black electro-coating to resist rust
• Micro-polished chrome-plated piston for low-friction operation
• Reinforced ABS ball socket connectors for secure, weather-resistant attachment

How difficult is installation for a DIY owner?

Replacing the Sorento tailgate struts is a straightforward two-person or single-person task that requires no specialized tools. The design uses snap-on ball sockets so you can remove the old supports and attach the new ones quickly using a common flathead screwdriver.

• Swap-out style: remove metal clip with flathead and unclip old strut
• Snap new ball sockets onto existing mounting posts until locked
• No special tools, hydraulic equipment, or professional installation required

Who is this for? If you own a 2011–2014 Kia Sorento and are seeing sagging hatch operation, slow lift, or unsafe drops, this KALUJ two-piece lift support set is aimed at everyday drivers, DIY mechanics, and independent repair shops that want a direct-fit, OE-spec replacement. It’s also suited for anyone who prefers a corrosion-resistant component with clearly stated dimensions and force rating (479 mm extended, 171 mm stroke, 610 N) to ensure predictable, factory-like rear hatch behavior. These struts are provided as a pair to maintain balanced lift force and hinge longevity, restoring convenience and safety to the vehicle’s rear access without overhauling other components.
