Heavy-duty replacement door check strap stopper for Nissan 350Z and INFINITI G35 (2003–2007) that prevents door slamming and restores smooth, controlled opening.

If your driver or passenger door feels loose, makes clunking noises, or fails to stay in position, the TUCKBOLD door check strap stopper offers a durable, affordable fix. Designed as a precise-fit aftermarket replacement for OE number 80430CD000, this two-piece kit restores the door’s stopping and holding function using rust-resistant metal components. It’s intended for front left and right doors and comes finished in black and silver tones to match the factory look.

How does this part improve a noisy or loose car door?

Replacing a worn check strap removes excessive play and eliminates the metallic clunking that happens when the original bracket degrades. The TUCKBOLD unit tightens the door’s movement path so it opens and holds smoothly at set points, reducing stress on hinges and reducing accidental slams. Installation corrects the common failure points that let the door swing freely or catch unexpectedly.

• Fits front left and right doors for Nissan 350Z (2003) and INFINITI G35 (2003–2007).
• Precision design for OE 80430CD000 replacement fitment.
• Restores controlled door stops and reduces noise from loose parts.

What materials and finishes protect this door check strap from corrosion?

The assembly is built from metal with an anti-rust coating applied to the surfaces most exposed to moisture and road salts. That finish extends service life compared with untreated brackets and reduces the chance of seizing or accelerated wear. The visible pieces arrive in black and silver tones to blend with the factory hardware.

• Metal construction for strength under repeated use.
• Corrosion-resistant coating for longer-lasting operation.
• Two-tone finish to match OEM appearance.

Is this part easy to install at home, or should I visit a shop?

Many owners can replace the door check strap using basic hand tools in a home garage; the unit is designed for straightforward swap-in replacement where original mounting points remain intact. If mounting holes have elongated or the door hinge hardware is damaged, professional attention may be required to restore proper alignment. TUCKBOLD recommends inspecting fasteners and surrounding brackets during replacement.

• Simple bolt-on replacement when factory holes are undamaged.
• Use common sockets and screwdrivers; typically a short DIY job.
• Shop service advised if mounting points are worn or distorted.

Will this aftermarket part fit my vehicle and what should I check first?

Before ordering, confirm your vehicle make, model, year, and OE reference—this TUCKBOLD kit is designed for Nissan 350Z (2003) and INFINITI G35 (2003–2007) matching OE number 80430CD000. Verify the door side (front left or front right) and inspect the current bracket and mounting holes; heavy corrosion or ovalized holes can affect fitment. Replacement works best when the surrounding structure is sound.

• Compatible with OE number 80430CD000 as an aftermarket alternative.
• Confirm model year and door side before purchase.
• Inspect existing holes and adjacent brackets for wear or distortion.
