Front Left Door Check Stop Strap for 2017-2021 Tesla Model 3 | 1089507-00-D

1. Key Specifications & Compatibility

2. Why This Brand-Grade Stop Strap Is Critical for Your Model 3

1. Prevents Damage from Over-Swinging: Limits the door’s maximum opening angle to ~65° (factory standard), stopping it from hitting curbs, garage walls, or other obstacles that could dent the door edge or break the hinge.
2. Secures Door in Partial Positions: Features built-in "detent points" that hold the door at 30° and 45° open positions. This keeps the door from slamming shut in wind or rolling closed on slopes, making it easier to load groceries, install child seats, or enter/exist the vehicle.
3. Reduces Hinge Stress: Distributes the door’s weight evenly when open, preventing excessive strain on the door hinges (a common cause of hinge wear or squeaking in older Model 3s with faulty stop straps).

3. What It Actually Does (No Tech Jargon)

• Stops Over-Opening: When you swing the front left door wide, the strap tightens at the maximum safe angle (no more accidentally hitting the door on a parking curb).
• Holds Door Steady: If you open the door halfway to grab a bag from the front seat, the strap “clicks” into place and keeps it from closing on your hand or blowing shut in wind.
• Feels Like Factory: Unlike flimsy generic straps, this one moves smoothly with the door—no jerky movements, squeaks, or stretching. Closing the door feels tight and secure, just like when your Model 3 was new.
• Tough for Daily Use: The reinforced webbing doesn’t fray from repeated opening/closing (even if you use the door 10+ times a day) and the steel hardware won’t rust from rain or road salt.

4. Signs Yours Needs Replacement

• Door Swings Too Far: The front left door opens wider than usual (past the normal 65° angle) and may hit curbs or walls.
• Door Won’t Stay Open: The door closes on its own when parked on a slope, or won’t hold in partial-open positions (e.g., it slides shut when you’re loading items).
• Loose/Wobbly Door: The door feels unstable when opening/closing—you may hear rattling or feel the door “shift” unexpectedly.
• Visible Damage: The strap is frayed, torn, or stretched; or the mounting hardware is rusted, loose, or missing.
• Squeaking Noises: Loud squeaks come from the door area when opening/closing (caused by a worn strap rubbing against the mounting points).

5. Why This Brand-Grade Strap Outperforms Generic Alternatives

• Tesla-Spec Material: Uses multi-layered polyester webbing (same thickness and strength as factory) instead of thin nylon (which stretches or tears in 6–12 months). The steel hardware has anti-corrosion plating (unlike generic zinc-plated bolts that rust quickly).
• Perfect Fit, No Mods: Mounts using the Model 3’s original bolt holes in the door and A-pillar—no drilling, filing, or trimming required. The included bushing matches the factory’s vibration-dampening design (avoids door rattle when driving).
• Factory-Like Detent Points: Calibrated to hold the door at the same 30°/45° positions as the original strap (generic straps often have poorly placed detents that don’t hold the door securely).
• Long-Lasting Durability: Resists UV damage (won’t fade or crack in sunlight) and moisture (works in heavy rain or snow without degradation)—built to last 5+ years, vs. 1–2 years for generic straps.
