Wilwood 200-7550 Thermlock Caliper Piston - 1.88

The Wilwood 200-7550 is a 1.88-inch diameter Thermlock caliper piston designed to provide superior thermal protection in high-performance braking systems. This replacement piston is engineered to significantly reduce heat transfer from brake pads to the caliper assembly, helping maintain optimal brake performance under extreme conditions.

Key Features:

• Exclusive Thermlock multi-part design with stainless steel heat shield and coated aluminum shell
• Reduces heat transfer by at least 25 percent compared to conventional pistons
• 1.88-inch piston diameter for precise caliper compatibility
• Prevents seal crystallization and brake fluid boiling
• Minimizes caliper body distortion and extends service life
• Direct replacement for compatible Wilwood calipers

By creating an effective thermal barrier between the friction surface and critical caliper components, the Thermlock piston helps maintain consistent brake performance and reliability. The innovative construction protects seals and brake fluid from excessive heat, reducing maintenance requirements and improving overall braking system longevity.
