Keep your trunk lid propped up and out of your way with the Tuff Support Trunk Lid Lift Support (MPN 614431). It drops in as a direct-fit replacement for the listed applications — the 2006-2015 Mazda MX-5 and 2006-2015 Mazda MX-5 Miata (All engines) — restoring the effort-free lift you expect when the original strut has worn out.
A lift support does one job: it holds the trunk lid raised and controls its motion as it opens and closes. When the strut weakens, the lid may drift down on its own, feel heavy to raise, or refuse to stay up. If a tired lift support is the cause, this unit replaces it.
- Function: Supports and holds the trunk lid in the open position for hands-free access.
- Signs it may need replacing: Lid won't stay up, drops slowly, or requires you to hold it manually.
- Quantity: Sold individually; the listed applications use two, so order two to replace the pair together.
Replace both sides at the same time for even, balanced support.
Interchange: Manufacturer part number 614431.
Frequently Asked Questions
What does this lift support do?
It holds the trunk lid in the raised position and controls its motion as it opens and closes, giving you hands-free access to the trunk.
Which vehicles does it fit?
It's a direct-fit replacement for the 2006-2015 Mazda MX-5 and 2006-2015 Mazda MX-5 Miata (All engines). See the Buyer's Guide tab to confirm your vehicle.
How many do I need?
It's sold individually, and the listed applications use two. Order two so you can replace both sides together for even support.
How do I know mine is worn out?
Common signs are a trunk lid that won't stay up, drifts down on its own, or feels heavy to raise. If a tired lift support is the cause, this replaces it.
Should I replace both sides at once?
It's recommended. Replacing both lift supports together keeps the lid balanced and supported evenly, since the second one is often near the end of its life too.
