Wilwood Aero4 Rear Big Brake Kit
2011–2018 RAM 1500
Part #: 140-16026-R
Overview
The Wilwood Aero4 Rear Big Brake Kit is a precision-engineered performance upgrade tailored for 2011 through 2018 RAM 1500 trucks. Designed to replace the factory rear disc brakes, this kit integrates seamlessly with the original parking brake assembly, ensuring a straightforward upgrade without compromising functionality. Ideal for RAM 1500 owners who have enhanced their trucks with larger wheels, tires, or suspension modifications, this kit delivers significantly improved stopping power and brake durability under demanding conditions.
Featuring Wilwood’s renowned Aero4 four-piston calipers and oversized 15.00-inch slotted rotors, this rear big brake kit provides superior heat dissipation and consistent braking performance. It perfectly complements front big brake upgrades, offering balanced and reliable braking for towing, hauling, or spirited driving.
Key Features
This Wilwood rear big brake kit combines advanced materials and engineering to elevate rear braking performance beyond stock capabilities. Key features include:
- Four-piston Aero4 calipers with a durable red powder coat finish for enhanced clamping force and a striking appearance
- Oversized 15.00-inch slotted rotors designed to improve heat management and reduce brake fade during heavy use
- BP-20 high-performance brake pads optimized for street driving and light track applications
- Stainless steel braided flex lines that replace factory rubber hoses, providing superior durability and a firmer brake pedal feel
- Radial mount caliper design for increased stiffness and improved braking response
- Maintains compatibility with the original equipment parking brake assembly for hassle-free installation
- Matched to the OEM master cylinder output and ABS system to ensure safe, balanced braking performance
- Requires a minimum 19-inch wheel diameter for proper fitment
Construction & Design
The Aero4 calipers are crafted from aerospace-grade aluminum, offering an excellent strength-to-weight ratio along with corrosion resistance. The red powder coat finish not only enhances visual appeal but also provides protection against environmental wear. The rotors are precision-machined from high-quality cast iron and feature slotted surfaces that improve pad bite, channel away brake dust and gases, and extend rotor life.
Replacing the factory rubber brake lines, the stainless steel braided flex lines resist expansion under pressure, resulting in a more consistent brake pedal feel and improved overall braking performance, especially under heavy loads or high gross vehicle weight conditions.
Installation & Fitment
The Wilwood Aero4 Rear Big Brake Kit is designed for direct bolt-on installation on 2011–2018 RAM 1500 trucks using the OEM rear axle and brake mounting points. It retains the original parking brake hardware, eliminating the need for modifications in that area. Installation requires wheels with a minimum diameter of 19 inches to accommodate the larger rotors and calipers.
This kit is an excellent choice for enthusiasts upgrading their front big brake system or those seeking enhanced rear braking performance for towing, hauling, or performance driving.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
