Wilwood 140-16629-D Rear Disc Brake Kit for UTV Side-by-Side

The Wilwood 140-16629-D rear disc brake kit delivers a significant braking performance upgrade for UTV and side-by-side vehicles. This complete kit features dynamically-mounted rotors paired with high-performance multi-piston calipers designed to handle the demands of higher-powered machines and rough terrain.

Key Features:

• Forged aluminum differential-bore calipers with four or six pistons for increased clamping force and reduced deflection
• High-friction steel rotors up to 20% larger in diameter with increased thickness to resist distortion under heat
• Dynamic rotor mounting system reduces thermal stress and prevents piston knockback on rough terrain
• Fixed-mount caliper design provides more uniform pad engagement for improved braking feel and control
• Greater brake torque compared to stock UTV brake systems

This rear brake kit is engineered to work seamlessly with Wilwood's front UTV brake kits for a complete braking system upgrade. The dynamic rotor mounting allows the rotor to expand and contract with temperature changes while maintaining proper alignment, ensuring consistent performance in demanding off-road conditions.
