Features:

A core accessory specifically designed for the braking systems of remote-controlled model cars, focusing on high strength and braking stability. Its core advantages are as follows:
Ultra-Hard & Durable: Made of high-hardness alloy material, it boasts strong deformation resistance, is less prone to fatigue fracture after long-term use, and provides stable pressure support for brake pads.
Optimized Braking: Precise hardness setting reduces brake clearance wobble, improves response speed, and avoids uneven brake pad wear and insufficient braking force.
Wide Compatibility: Compatible with the braking systems of multiple car models. It can be easily installed and directly replace the original factory spring, helping model car enthusiasts quickly upgrade to a high-strength braking experience.
