Crane Axle Rear Unit Bearing 4 Piston Wilwood Lightweight Brake Kit

Forged Wilwood Dynalite 4 Piston Calipers

Precision-forged billet aluminum calipers provide greater strength and reliability than cast designs. The 4-piston layout produces a total piston area of 4.80 sq. in., delivering maximum clamping force with reduced pedal travel and superior modulation under heavy braking.

13.5” Wilwood Vented Rotors for More Stopping Power

Larger rotors generate greater torque and more friction per pedal stroke. At 13.5”, the Wilwood rotors offer enhanced braking performance by increasing the leverage on the wheel, allowing faster deceleration with less pedal effort.

Lightweight Design to Reduce Unsprung Weight

Every ounce matters in performance. With 13.4 lb rotors and 3.4 lb calipers, this kit significantly cuts unsprung weight and rotating mass, improving suspension response and acceleration while keeping your tires planted in demanding terrain.

Machined 6061 Aluminum Rotor Hats

Each Crane Axle rotor hat is machined and coated for corrosion resistance. Designed for ideal offset and balance, these hats ensure a perfect fit that complements the entire system while minimizing rotational inertia.
