Is the Redline Tuning 21-20003-02 Hood Quicklift Fits worth buying for your vehicle? If you own a North American Jeep Wrangler JL or Gladiator with a stock aluminum hood and want to lift it without wrestling a prop rod, it is worth it. It is not worth it if you own a steel-hood trim, an aftermarket hood, or a Rubicon 392, because the listing warns those setups need higher-force struts to hold the extra weight safely.
Good for: North American Wrangler JL and Gladiator owners with standard aluminum hoods who want easy bolt-in lifting. Not for: Owners of Mojave, Rubicon 392, international steel-hood, or aftermarket hood Jeep builds.
What it stakes its case on
This kit builds its argument around four clear mechanical features from the listing. First, it uses progressive-rate valving inside the gas springs to deliver end-of-stroke dampening. The listing explains that this slows the lift over the final inches of travel, which lowers stress on the mounting points and your factory hood. Second, the mounting hardware is double-treated steel that receives zinc plating and a black powder coat for surface protection. Third, it installs as a bolt-in setup using existing holes, so you do not have to drill into your body panels. Fourth, the lower mounts include a quick-release mechanism that lets you release the hood from the gas struts, allowing it to extend back to the windshield as if struts were not installed.
Together, these details address the full job of holding an aluminum hood securely. The package gives you the struts, the treated brackets, and the quick disconnects needed to replace your factory prop rod. However, it only solves that job for the specific aluminum panels it was engineered to lift.
Which claims have something behind them
The strongest claims in the listing are backed by exact engineering descriptions and a stated guarantee. The maker stands behind the parts with an explicit 4-year warranty covering all Quicklift Plus components. The protection against rust is also specific: the steel hardware is zinc plated first, then finished with a black powder coat. The dampening claim is supported by progressive-rate valving that explicitly slows the movement at the end of the stroke.
On the other hand, phrases describing simple hand tools reflect subjective claims that depend entirely on what tools you already own. The listing does not itemize the exact wrench or socket sizes you need in the box description. It also labels the system as an “All Black System,” which describes the cosmetic finish rather than a structural benefit. Even so, the compatibility warnings are remarkably clear: the manufacturer explicitly names the specific alternative part numbers needed for steel or heavy-duty hoods.
Specifications
The manufacturer provides the following verified specifications for the lift system:
| # | What Amazon lists |
|---|---|
| 1 | Fitment – Redline Tuning’s 21-20003-02 is compatible with Jeep Wrangler JL (2018+) & Compatible with Jeep Gladiator (2020+) for North America. All Aluminum Hoods are supported. (This system is NOT compatible with vehicles outside North America that have Steel Hoods, Mojave edition, 392, & aftermarket hoods which all require higher force struts). Purchase 21-20004M for (Mojave or vehicle outside North America), purchase 21-20007 for Rubicon 392 model. |
| 2 | Bolt-in System – This Hood Quicklift System is designed and engineered to use existing mounting locations for our vehicle-specific mounting hardware. Simple hand tools only, no drilling or vehicle modifications required. |
| 3 | Quicklift Plus (All Black System) – All installation hardware is designed to last as all metal is double-treated. Steel mounting-hardware is zinc plated, then black powder coated for both appearance and added corrosion protection. There is a 4 year warranty on all Quicklift Plus components. |
| 4 | Quick-Release – Both lower strut attachments include a quick-release mechanism that allows the hood to be released from the gas struts. Your hood will then extend back to the windshield as if the struts were not installed. Simply snap them back on to utilize your Hood QuickLIFT System. |
| 5 | End-of-stroke-dampening – All gas springs utilize progressive-rate valving technology. Designed into each gas spring is an end-of-stroke dampening which slows the rate of extension over the final inches of travel. This feature reduces stress on hood and mounting hardware. |
A plainer one: what you give up
A plainer hood support in this category is the standard metal prop rod that came with your vehicle from the factory. Choosing to stay with a plainer setup means you give up hands-free lifting, smooth hydraulic dampening, and an open engine bay. You have to lift the hood manually with one arm while finding the small slot for the metal rod with the other, which can be awkward in wind.
A standard prop rod also cuts straight across the engine bay, blocking access to fluid reservoirs and wiring on that side of the vehicle. However, sticking with the plainer factory rod is the smarter choice if you rarely look under your hood. If you only pop the latch twice a year for routine fluid checks, the factory rod does the job without adding mechanical parts.
A more capable one: what you gain
Stepping up to a more heavy-duty hood strut kit gives you significantly higher lifting force. The manufacturer notes that their heavy-duty systems, like the separate kits designed for the Mojave or Rubicon 392, provide the extra pressure required to support steel panels. If you plan to install heavy steel armor, hood louvers, or an aftermarket cowl hood, stepping up to a high-force kit is necessary.
If your build includes aftermarket front-end modifications or heavy paneling, taking that step up to a dedicated high-capacity strut system is the only safe path.
What owning it asks of you afterwards
Owning this lift system does not require recurring consumables, subscriptions, or fluid refills, but it does require mechanical awareness. Gas struts rely on pressurized internal seals, which means they can slowly lose lifting force over many years of seasonal temperature swings. The listing mentions that the steel hardware uses zinc plating and powder coating, but road salt and grit will still accumulate on the bracket surfaces.
You will need to keep the lower quick-release pivot points free of packed mud and grime so the release mechanism does not jam when you need to fold the hood back.
How much use it has to stand up to
How well this kit holds up depends heavily on how often you work under the hood and where you store your rig. For a daily driver that encounters highway salt and rain, the double-treated zinc and powder-coated steel hardware protects against early cosmetic rust. The progressive-rate valving also protects the mounting hardware from snapping under sudden shock loads by slowing the hood before it reaches maximum extension.
Verdict by how hard you will use it
The Occasional Under-Hood Checker
Buy it. If you only open the hood for washer fluid refills and monthly oil checks, the bolt-in hardware and dampening will easily outlast your basic needs.
The Regular Weekend DIY Mechanic
Buy it. If you spend your weekends wrenching on accessories, the quick-release struts let you tilt the hood back to the glass for maximum light and engine access.
The Heavy-Duty Armor Builder
Skip it. If you have installed a steel aftermarket hood, a Mojave trim, or a Rubicon 392, this unit lacks the lifting force you need; look for the manufacturer’s heavy-duty kits instead.
The questions that decide it
Does this kit work on all Jeep Wrangler JL and Gladiator trims?
No. The listing states it only fits North American models equipped with factory aluminum hoods. It will not work on vehicles outside North America that use steel hoods, nor will it support Mojave, Rubicon 392, or aftermarket hoods because those setups require higher-force struts.
Do I have to drill into my Jeep to install these struts?
No, the manufacturer built this as a direct bolt-in system that utilizes existing factory mounting holes. You do not need to cut, drill, or modify your body panels, though the listing confirms you will need simple hand tools to secure the vehicle-specific mounting hardware into place.
Can I still tilt the hood all the way back to the windshield?
Yes. Both lower strut attachments feature a quick-release mechanism that allows the hood to be released from the gas struts. Once released, you can fold the hood completely back against your windshield frame just like a stock setup, and snap the struts back on when you finish.
What is covered under the product warranty?
The listing states that all Quicklift Plus components come backed by extended warranty protection. This coverage applies to the complete black system, including the zinc-plated, powder-coated mounting hardware and the progressive-rate valving gas springs.
