Wilwood Forged Superlite 4 Brake Caliper with 1.88/1.75 Inch Pistons and .81 Inch Disc – Part Number 120-11137

Description

The Wilwood Forged Superlite 4 caliper (Part Number 120-11137) is engineered for high-performance braking in demanding racing and off-road environments. Featuring advanced differential bore pistons, this caliper enhances pad wear performance by compensating for mechanical loading and temperature variances across the pad face, making it ideal for sustained high-temperature applications such as dirt and asphalt ovals, rally, and off-road racing. The caliper’s design reduces pad taper wear, ensuring consistent braking performance over extended use. The ST models incorporate Thermlock® pistons, which block heat transfer from the pads, lowering temperatures in the caliper, fluid, and seals by up to 25% compared to standard stainless steel pistons, providing critical heat protection during intense braking conditions. Constructed from forged aluminum, the caliper offers a balance of strength and weight savings, contributing to improved handling and acceleration. Its compact size and robust design make it suitable for a wide range of racing applications where durability and thermal management are paramount.
