Wilwood 120-16190-P Forged Dynapro Piston Brake Caliper Mount - 4 5.25in Polished

The Wilwood Forged DynaPro-Low Profile (FDP-LP) billet brake caliper delivers enhanced stopping power and precision engineering for high-performance braking systems. This forged 4-piston caliper is specifically designed for applications with limited outboard rotor hat clearance and narrow swept area rotors, making it an ideal upgrade or replacement for Dynalite model calipers.

Advanced Forged Construction:

Manufactured using stress-flow forging from premium grade billet, this caliper features a realigned grain structure that follows the contour of the body design. This process creates superior strength compared to standard machined billet components. The FEA-optimized body design incorporates a fortified radial transition between piston housings and bridges, eliminating weak points and dramatically increasing resistance to deflection under heavy braking loads. The result is reduced fluid volume displacement and less pedal travel for more efficient clamping power.

Key Features:

• Four piston design with 1.38/1.38-inch bore diameter for balanced clamping force
• 5.25-inch lug mount configuration with polished finish
• 0.81-inch rotor thickness compatibility
• Heavy wall stainless steel pistons resist corrosion and reduce heat transfer
• Quick-E-Clip pad retainers allow fast pad service without caliper removal
• Low-profile design with removed bottom pad supports for tight clearance applications
• SRS bridge plates eliminate bridge wear and prevent pad rattle and squeal
• Internal fluid passages with four-corner bleeder screws for universal mounting
• Compatible with 4812-type brake pads

The universal mounting design allows installation in front, rear, left, or right positions. The stainless steel pistons provide additional strength against backside deflection, ensuring firm pedal feel even with power-assisted braking systems.
