The Wilwood Big Brake Kit offers upgraded components for your UTV / Side-by-Side, including dynamically-mounted rotors and enhanced calipers. This kit features fixed mount multi-piston calipers that provide greater clamping force compared to stock, along with larger diameter floating rotors for increased brake torque and improved braking performance on more powerful UTVs. Crafted with forged aluminum differential-bore four or six piston calipers to reduce deflection and ensure consistent engagement, resulting in enhanced braking force and pedal feel. The high-friction steel rotors are larger and thicker (up to 20% greater in diameter and thicker), reducing distortion, while the dynamic mounting minimizes thermal stress and prevents piston knockback on rough terrain.
