Wilwood 120-9687-BK DynaPro Single Billet Disc Brake Caliper Mount - 3.25

The Wilwood DynaPro Single (DPS) billet caliper represents the latest evolution in high-performance disc brake calipers, designed as a direct upgrade or replacement for applications previously using the Dynalite Single (DLS) series. Combining superior strength with advanced performance features, the DPS delivers exceptional clamping efficiency and durability for demanding braking applications.

Advanced Billet Construction:

Fully CNC machined from premium grade aluminum alloy billet, the DPS caliper features an FEA-optimized body design with a fortified transition between the piston housings and bridges. This strengthening of critical stress areas substantially increases resistance to deflection and body separation under heavy braking loads, resulting in improved clamping efficiency with reduced pedal travel and fluid volume displacement.

Key Performance Features:

• Quick-E-Clip pad retainers support 6812 type brake pads from the top for fast pad service without caliper removal
• Heavy wall stainless steel pistons resist corrosion and reduce heat transfer from pads to brake fluid
• Increased piston wall thickness improves pedal firmness and eliminates piston backside deflection
• Replaceable stainless steel SRS bridge plates eliminate bridge wear from pad gouging
• Spring-loaded SRS plates eliminate pad rattle and dampen vibration harmonics that cause brake squeal
• Internal fluid passages with four corner bleed screws allow universal mounting in any front, rear, left, or right position
• 3.25" radial mounting configuration

The DPS caliper provides substantial performance improvements over previous DLS models through stronger pad retention, enhanced structural rigidity, and superior thermal management. Black anodized finish provides corrosion resistance and professional appearance.
