Wilwood 200-11343 Thermlock Brake Caliper Piston 1.25" x 0.88"

The Wilwood 200-11343 Thermlock brake caliper piston features an innovative multi-part design engineered to minimize heat transfer from brake pads to the caliper body, seals, and brake fluid. This replacement piston measures 1.25 inches in diameter with a 0.88-inch depth, making it compatible with specific Wilwood caliper applications.

Key Features:

• Thermlock technology reduces heat transfer by at least 25 percent compared to conventional pistons
• Multi-part construction with stainless steel heat shield and coated aluminum shell
• Prevents seal crystallization and localized brake fluid boiling
• Reduces caliper body and piston bore distortion for extended service life
• Precision-engineered dimensions: 1.25-inch diameter x 0.88-inch depth

Wilwood's Thermlock piston design provides a superior thermal barrier that maintains lower operating temperatures during aggressive braking conditions. By keeping heat away from critical caliper components, this piston helps maintain consistent brake performance and extends the lifespan of seals and brake fluid in high-performance braking systems.
