Locking Hood Pin Kit: Types, Benefits & How to Install
A locking hood pin kit keeps your hood secured at speed and locked against theft or prying — essential for lightweight aftermarket hoods, track cars, and show builds. Here’s how locking hood pins work, the main types, and how to fit a kit correctly.

🔎 Quick Answer: A locking hood pin kit replaces or supplements the factory hood latch with pins that bolt to the core support and pass through the hood, secured by a keyed lock, cam-lock or quick-release mechanism. They stop a hood from lifting at speed, hold down fiberglass/carbon hoods, and deter theft. Kits run about $25–$120 and most install with a few bolts and careful drilling.
What a Locking Hood Pin Kit Does
Hood pins do three jobs: hold the hood down securely at high speed, secure aftermarket hoods that don’t use the factory latch, and — in the locking versions — prevent the hood being opened without a key. Many racing bodies (such as NHRA classes) require hood pins on cars without a functional factory latch.
Types of Hood Pins
| Type | How It Works | Best For |
|---|---|---|
| Traditional pin & clip | Pin through hood, hairpin clip holds it | Track/strip cars, classic look |
| Locking (keyed) | Pin secured by a key barrel lock | Anti-theft, street cars, show cars |
| Quick-release / cam-lock | Push-button or quarter-turn, no tools | Fast pit access, race use |
| Hood pin + lanyard | Pin tethered so it can’t be lost | Daily/track convenience |

What’s in a Typical Kit
- 2 hood pins (threaded posts)
- 2 base/mounting plates that bolt to the core support
- Locking caps with keys (locking kits) or clips/lanyards
- Spring-loaded scuff plates/trim washers
- Mounting hardware and a drilling template (on better kits)
🛠️ Material tip: Choose billet aluminum or stainless steel pins — they resist bending and corrosion far better than cheap chrome-plated steel.
How to Install a Hood Pin Kit
- 1
Mount the base platesBolt the base plates to the radiator core support where the hood corners sit.
- 2
Mark the hoodCoat the pin tops with marker or grease, close the hood gently to transfer the exact drill points.
- 3
Drill the hoodDrill the marked holes to the pin diameter, deburr and add the supplied scuff/trim plates.
- 4
Fit the pins & test alignmentThread the pins, close the hood and confirm the pins pass cleanly through the holes.
- 5
Set height and lockAdjust pin height so the hood sits flush, then fit the locking caps/clips and test the key.
⚠️ Measure twice: Drilling the hood is permanent. Double-check alignment and clearance over belts/pulleys before you drill.
Frequently Asked Questions
Are locking hood pins legal on the street?
Hood pins themselves are street-legal in most areas, and locking versions add theft protection. If you remove the factory latch entirely, some regions require a secondary hood retention — check local rules.
Do I have to remove the factory hood latch?
Not necessarily. Many owners keep the factory latch and add pins for extra security or to satisfy track rules. Aftermarket hoods that lack a latch rely on the pins alone.
Will I have to drill my hood?
Most traditional and locking kits require drilling the hood for the pins. Some bolt-on or hinge-mounted kits avoid drilling — check the kit before buying.
Can locking hood pins be picked or forced?
Quality keyed locking pins resist casual tampering and are a strong deterrent, though no lock is absolute. They’re far better than exposed pin-and-clip styles for anti-theft.
What size hood pins do I need?
Common pin diameters are 3/8″ and 1/2″. Heavier hoods and high-speed use favor the larger 1/2″ pins for strength.
Securing a Hood the Right Way?
Pick billet or stainless locking pins, mount the plates solidly, drill carefully, and set the height so the hood sits flush.
