Wilwood 140-16631-DR UTV Front Rear Disc Brake Kit

The Wilwood 140-16631-DR is a complete matched front and rear disc brake upgrade kit designed for side-by-side UTVs. This performance brake system delivers significantly improved stopping power and brake feel for high-powered utility terrain vehicles operating in demanding off-road conditions.

Key Features:

• Forged aluminum differential-bore multi-piston calipers with fixed mounting for maximum rigidity and reduced deflection
• Larger diameter floating rotors (up to 20% larger than stock) for increased brake torque and heat dissipation
• Dynamically-mounted rotor design reduces thermal stress and prevents piston knockback on rough terrain
• High-friction steel rotors with increased thickness to minimize distortion under heavy braking
• Greater clamping force provides more uniform pad engagement and improved pedal feel
• Complete front and rear kit for balanced braking performance

This Wilwood UTV brake kit is engineered specifically for side-by-side machines that require upgraded braking capability beyond OEM systems. The forged aluminum construction and differential-bore piston design ensure consistent performance in the harsh conditions typical of UTV operation, while the dynamic rotor mounting system maintains proper caliper-to-rotor alignment even on extremely rough terrain.
