Wilwood 120-14707 DynaPro Dust Seal Four-Piston Radial Mount Brake Caliper Gray Anodized

The Wilwood DynaPro Dust Seal Radial Mount Caliper (DPR-DS) is a four-piston, stress-flow forged performance brake caliper engineered for sports, rally, and off-road driving applications that demand durability in harsh environments. The radial mount design offers flexible installation with a sleek, low-profile body built to handle the punishment of demanding road and track conditions.

This caliper features a gray anodized finish with a 1.620 in. piston diameter, and is sold individually. The dust boot and seal system work together to defend against road and track-born dirt, grime, and debris, making it an ideal choice for low-to-intermediate temperature applications operating in challenging environments.

Key Features:

• Stress-flow forged premium-grade billet aluminum — re-aligns the internal grain structure of the metal within the caliper body contour for superior strength over machined block billet or cast parts
• FEA-generated body design — radial transition between piston bores and caliper bridges eliminates machined steps and shoulders, substantially increasing resistance to deflection and body separation under high load
• Dust boot sealing system — dust boots work in conjunction with high-temperature, square-faced internal bore seals for optimum protection against environmental contamination
• Clear anodized pistons — eliminates corrosion while providing added lubricity for drag-free operation within the bores
• Quick-E-Clip pad retainers — allow for fast pad service without caliper removal for reduced downtime
• Four-piston opposed design — delivers firm, responsive pedal feel with outstanding stopping power
• Radial mount configuration — provides versatile mounting options with a sleek profile
• Compatible with rotors up to 12.19 in. diameter; Thermlock insulated piston options available for sustained high-heat applications

The Wilwood DynaPro DPR-DS caliper combines proven race technology with practical street and off-road performance enhancements. Structural deflection and volume displacement testing validate this caliper's efficiency and reliability under real-world high-load conditions. Available in a variety of configurations and finishes to suit specific application requirements.
