Big Brake Upgrade. The Baer SS4 Rear Big Brake Kit with 13-Inch Rotors and Desert Sand Calipers is engineered to significantly enhance rear braking performance for both off-road and street applications. This kit delivers superior stopping power and improved heat dissipation, helping to maintain vehicle control and safety under demanding conditions. It is an essential upgrade for Jeep owners seeking increased braking efficiency and durability.

Construction and Appearance. The kit features 4-piston S4 floating calipers, CNC machined in Phoenix, AZ, from US-sourced forged or billet aluminum for strength and lightweight performance. The calipers have a powder-coated finish and incorporate hard anodized aluminum pistons, stainless steel abutments, and noise suppression clips. The rotor is a 13-inch, one-piece vented and slotted design with zinc plating for corrosion resistance.

Installation. Installation is straightforward with all necessary mounting brackets and hardware included. The system is a direct bolt-on for stock rear axle configurations with no drilling required. Note that the kit does not include park brake components and reuses the OE park brake assembly. Brake hoses are also not included and must be sourced separately.

Application and Fitment. This kit fits 2007 through 2025 Jeep Wrangler JK and JL models, as well as 2020 through 2025 Jeep Gladiator JT models equipped with the original equipment rear end. It is designed for compatibility without modification for these vehicles, ensuring optimal fit and function. It fits most 17-inch or larger wheels; a wheel clearance template is available to confirm fitment.
