Wilwood Narrow Superlite 4R Rear Kit 12.88in Drilled Red 2007-up Jeep JK w/Lines

This Wilwood Narrow Superlite 4R rear brake kit is built around forged four-piston calipers, designed to work with 12.88-inch rotors. It's a substantial upgrade for your 2007-2015 Jeep Wrangler, especially if you're already looking at larger front brake kits, bigger tires, or suspension changes. The goal here is to give your JK a serious boost in stopping performance that matches its other upgrades.

Wilwood's FNSL4R calipers are a well-known choice for performance builds. They're paired with their BP-10 compound brake pads, which offer a good balance of stopping power and everyday drivability for street use. This kit includes drilled rotors, which help to dissipate heat and clear out dust and gas from the pad surface, leading to more consistent braking, especially under heavier loads or during spirited driving. The kit also comes with all the necessary brake lines, ensuring a complete installation. Importantly, this kit is designed to retain the use of your Jeep's original parking brake system, master cylinder output, and ABS functionality where applicable, making it a more integrated upgrade.

When you're stepping up your Jeep's performance with larger tires and potentially more power, your braking system needs to keep pace. This Wilwood kit provides that capability, offering a significant improvement over the stock setup. It’s a popular choice for JK owners looking to build a high-performance street or show Jeep that can also handle itself when the pavement ends.
