Impulsring Spacer
It ensures accurate sensor positioning by creating the precise spacing needed for reliable signal detection. Manufactured from high-strength steel, the spacer resists deformation, vibration, and heat, ensuring long-term stability in heavy-duty applications. Its accurate thickness guarantees consistent air gap measurement, which is essential for proper ABS modulation and wheel-speed accuracy.
By maintaining the correct sensor-to-ring distance, the Impulsring Spacer enhances braking safety, prevents ABS errors, and supports smooth vehicle operation even under harsh road conditions.
Key Features
- Precision spacer for ABS impuls/tone ring positioning
- Ensures accurate air gap for proper ABS sensor function
- High-strength steel construction for durability
- Resists wear, heat, and vibration
- Essential for stable ABS braking performance
