Spacer Plate 3/8in GM Caliper

The HOWE Spacer Plate 3/8in GM Caliper is a precision-engineered component designed for GM brake system modifications, particularly when upgrading caliper sizes or adjusting pad clearance on street and performance vehicles. This spacer plate serves as a critical intermediary between the caliper body and mounting hardware, allowing builders to fine-tune brake geometry without fabricating custom brackets.

Manufactured by HOWE, a trusted name in brake system fabrication, this 3/8-inch spacer plate is precision-machined from quality materials to ensure consistent thickness and flatness—critical factors for proper caliper seating and brake balance. The compact dimensions (2.3 x 0.45 x 7.2 inches) accommodate standard GM caliper mounting patterns without requiring frame or suspension modifications. The lightweight 0.51-pound design makes it ideal for weight-conscious builds, while the precision tolerances ensure zero runout and prevent rotor-to-caliper contact issues that can cause noise, vibration, or uneven pad wear.

This spacer plate is essential for hot rodders, restoration enthusiasts, and track-focused builders working with GM vehicles—from classic Chevrolet models to modern performance cars. Its design allows for seamless integration with various brake upgrades, ensuring optimal performance and reliability in demanding driving conditions.
