Description

Excessive heat is the silent killer of brake performance—it crystallizes seals, boils fluid, and distorts caliper geometry, all of which compromise stopping power and shorten component life. The Wilwood Thermlock Piston tackles this problem head-on with a dual-material thermal barrier that cuts heat transfer by at least 25%, keeping your braking system operating at optimal temperature during sustained track sessions or heavy braking events. If you're running a high-performance brake setup, this piston is a straightforward upgrade that directly extends caliper longevity and maintains consistent pedal feel lap after lap.

  • Length: 1.05 inches
  • Materials: Stainless steel shield, coated aluminum shell
  • Heat reduction: Minimum 25%
  • Compatible calipers: W6Ar, W4Ar, Superlite, NDl, NDp, GN lll
  • Sold individually
  • Installation: Caliper disassembly required
