Wilwood 140-16631-R Rear Disc Brake Kit for UTV Side-by-Side

The Wilwood 140-16631-R is a high-performance rear disc brake kit engineered specifically for UTV and side-by-side vehicles. This complete brake system upgrade delivers significantly improved stopping power and heat management for high-powered off-road machines operating in demanding terrain conditions.

Key Features:

• Forged aluminum differential-bore caliper with multi-piston design provides greater clamping force and reduced deflection
• Larger diameter floating rotors deliver increased brake torque compared to stock systems
• High-friction steel rotors are up to 20% larger in diameter and thicker construction for improved heat dissipation and reduced distortion
• Dynamically mounted rotor design minimizes thermal stress and prevents piston knockback on rough terrain
• Fixed-mount caliper design ensures more uniform pad engagement for improved pedal feel and consistent braking performance
• Complete bolt-on kit designed to integrate with Wilwood front brake systems for balanced braking dynamics

This rear brake kit is ideal for UTV owners seeking maximum braking performance for trail riding, racing, or heavy-duty applications. The upgraded rotor size and caliper design work together to reduce brake fade and maintain consistent stopping power during extended use.
