Product Description

The Wilwood 120-11133 Forged Superlite Internal Caliper features a high-strength forged aluminum body and four-piston design for consistent, progressive braking performance in custom brake systems. With dual piston sizes of 1.62" and 1.25", this caliper delivers improved pad engagement and modulation across a wide range of applications.

Ideal for street, track, and performance builds, the internal piston layout reduces unsprung weight and improves handling. Precision-machined bores ensure smooth piston movement and enhanced pedal feel, while the durable finish protects against corrosion in demanding environments.

Because this caliper is universal, compatible mounting brackets and brake pads must be selected separately to match your vehicle's rotor size and configuration. This makes the 120-11133 a flexible choice for enthusiasts, fabricators, and racers looking to upgrade their brake setup with a high-performance, lightweight component.
