The seat track cover—a small but critical component that protects the seat’s sliding mechanism from dust, debris, and wear. If you’ve noticed your seat sliding unevenly, hearing unusual squeaks, or spotting visible damage to the cover, you may need the specific replacement part: Lexus part number 721580R010C0.
In this guide, we’ll break down what this part does, which vehicles it fits, common signs it needs replacement, and how to choose a reliable replacement—including why Loosoo, a trusted name in automotive accessories, is a smart choice for quality and compatibility.
What is Lexus Part Number 721580R010C0?
The 721580R010C0 seat track cover is designed to shield the seat’s sliding track from external contaminants while ensuring smooth, quiet operation. Found in select Lexus and Toyota models, it’s a factory-specific component engineered to match the exact dimensions and materials of the original part.
Which Vehicles Does It Fit?
This part is commonly used in Lexus luxury sedans and Toyota models known for their premium interiors. Based on Lexus’ historical focus on craftsmanship (dating back to its 1989 launch with the LS and ES series), it’s frequently found in:
- Lexus NX models
- Lexus RX sedans
- Select Toyota luxury variants
If your vehicle’s seats slide on a visible metal track, there’s a high chance the 721580R010C0 cover is the correct replacement.

Signs Your Seat Track Cover Needs Replacement
A worn or loose seat track cover isn’t just an aesthetic issue—it can lead to costly damage over time. Here are key red flags:
- Visible cracks or tears: The cover may split due to age, UV exposure, or physical impact.
- Squeaking or grinding noises: Debris entering the track causes friction as the seat slides.
- Rough or uneven seat movement: Dirt buildup can jam the track, making it hard to adjust the seat.
- Loose or missing clips: The cover is held in place with small fasteners; if these break, the cover will sag or detach.
Ignoring these signs can accelerate wear on the seat track itself, leading to more expensive repairs down the line.
