Koaudb 2Pcs Boot Struts for Hyundai i20 (2015–2020) Rear Tailgate – 450N Heavy-Duty Gas Strut Replacement
Product description
What it is
Koaudb offers a pair of rear boot gas struts designed to replace the tailgate lift supports on the Hyundai i20 5‑door from 2015 to 2020. These are rated at 450N and use hydraulic spring technology to help control the opening and closing of your boot. The goal is to restore smooth operation and reduce stress on cables and hinges that can wear over time.
Who it’s for

If your i20’s tailgate feels reluctant to stay open, drops unexpectedly, or the gas struts look dented or corroded, these replacements aim to bring back stable, controlled movement. They’re positioned as a direct replacement for the OEM numbers 81770C8010, 81780C8010, 81770C8000 and 81780C8000, so matching the original part is important before purchase.
What stands out in use
On the surface, the design relies on sturdy stainless steel construction and a thick-walled cylinder to handle higher bearing pressure. The hydraulic mechanism is intended to offer smoother operation and better sealing, helping to minimise air or oil leakage. In practice, that translates to a tailgate that opens more predictably and closes with less effort.



The trade-offs
No product description can guarantee perfect longevity, and this kit does not remove all wear from the boot hinges or cables. If your vehicle has unusually heavy tailgate use, or if the existing mounting points show damage, the struts may require additional attention. Also, the fitment hinges entirely on selecting the correct OEM number for your car, a mismatch could compromise performance.
How it fits your Hyundai i20

The kit targets Hyundai i20 5‑door models from 2015 through 2020, aligning with the rear tailgate gas strut configuration. If you’re unsure about which OEM number you need, compare with the original part on your vehicle before purchasing, as the base notes emphasise verifying the OEM code.
Practical usage example
Imagine you’re loading groceries on a windy day. With these struts, the tailgate should rise smoothly and stay open without you having to prop it manually. When you’re done, a controlled descent helps protect the hinges and keeps the tailgate from slamming shut.



What to check before buying
- Confirm the OEM part number on your current strut matches one of the listed numbers (81770C8010, 81780C8010, 81770C8000, 81780C8000).
- Ensure your i20 is within the 2015–2020 model range and that the tailgate mounting points are undamaged.
- Consider whether you need a direct replacement versus a renewal that also addresses hinge wear or cable strain.

What to know before you buy
If you prioritise a straightforward replacement that restores normal tailgate operation without extra frills, this kit sits in the practical, mid‑range category. It isn’t a universal fit for all tailgates, and the success of installation hinges on correct OEM compatibility and mounting integrity. If your goal is basic reliability and smoother operation rather than bespoke tuning, these struts are a sensible option.

FAQ
- Q: Will this fit my Hyundai i20 2016? A: It should, provided the OEM number on your current strut matches one of the specified codes.
- Q: Are these heavy‑duty struts compatible with a very heavy tailgate? A: They are rated at 450N, which is intended for normal to moderately heavy loading, if your boot frequently bears heavy loads, inspect hinges and cables as well.

Buying verdict
Buying verdict: Worth considering if you need a targeted replacement that restores smoother tailgate action on an Hyundai i20 (2015–2020) and you’ve confirmed OEM compatibility. It may not be the best option if your tailgate hardware shows significant wear beyond the struts or if you require a non‑OEM alternative with a different mounting approach.
