Dynapro Billet Caliper Side Inlet 1.75/.380

The WILWOOD Dynapro Billet Caliper Side Inlet 1.75/.380 is a four-piston aluminum brake caliper engineered for high-performance and heavy-duty vehicle applications. Built from billet aluminum and finished in gray anodize, this caliper delivers the thermal stability and stopping power required by serious performance drivers who demand reliability under extreme braking conditions.

The side inlet design allows for flexible brake line routing, simplifying installation on custom and modified vehicles where clearance is tight or unconventional layouts demand adaptability. With a piston bore of 1.75 inches and a rotor thickness specification of .380 inches, this caliper generates consistent clamping force across a wide range of driving intensities—from daily street driving to track use and demanding recreational applications. The billet aluminum construction resists thermal fade and maintains structural integrity during repeated hard stops, while the gray anodize finish protects against corrosion in varied weather conditions.

This caliper suits builders and enthusiasts upgrading brake systems on vintage muscle cars, street rods, off-road trucks, and modern performance platforms where OEM braking falls short. Street rodders, race car builders, and off-road competitors value WILWOOD's established reputation for durability and stopping performance. The compact profile and side inlet configuration make this unit compatible with various wheel and suspension setups, reducing the need for custom adapter brackets on many common applications.

WILWOOD calipers serve as core components in brake system upgrades where weight reduction, thermal performance, and customization flexibility are priorities. Buyers sourcing replacement calipers, completing brake system rebuilds, or designing new high-performance brake packages rely on WILWOOD's proven four-piston technology and billet construction to deliver consistent results across diverse vehicles and driving conditions.
