Wilwood 200-9342 – 2.00" GM Stainless Brake Caliper Piston

Wilwood 200-9342 – 2.00" GM Stainless Cup Brake Caliper Piston

The Wilwood 200-9342 Stainless Cup Caliper Piston is engineered for GM-style racing brake calipers where durability, thermal control, and consistent piston performance are critical. Manufactured using Wilwood’s proprietary stainless stamping process, this piston resists deformation and prevents “oil canning” under high hydraulic pressures.

The thin-wall cup-style construction offers low thermal conductivity, helping reduce heat transfer from the brake pads into the caliper body, seals, and brake fluid. Built from a high-strength proprietary stainless steel alloy and finished with a bright machined surface, this piston ensures smooth operation, proper sealing, and long service life.
