Wilwood 120-16566 Forged Aluminum Disc Brake Caliper for UTV

The Wilwood 120-16566 is a forged aluminum disc brake caliper specifically engineered for the UTV market. Available in both UTV4 (four piston) and UTV6 (six piston) configurations, this caliper features a differential-bore design that optimizes braking force distribution across the rotor surface.

Key Features:

• Forged aluminum construction with advanced ASM design reduces caliper deflection under heavy braking
• Differential-bore piston configuration provides more uniform pad engagement for improved braking force
• Stainless steel pistons resist corrosion and reduce heat transfer
• Anti-knock back springs maintain optimal piston positioning and enhance pedal feel
• Compatible with standard 7812 shape high-friction brake pads

This caliper's forged construction delivers superior strength-to-weight ratio compared to cast designs, making it ideal for demanding UTV applications where consistent braking performance is critical. The stainless steel pistons and integrated anti-knock back spring system work together to provide confident, responsive pedal feel in all conditions.
