Wilwood 140-18294 XRS4R Rear 14" Big Brake Kit, Black for Big Ford New Style 2.50" Offset

The Wilwood XRS line of Rear Big Brake Kits from Accesspeed represents the next generation of hi-tech engineering and performance, combining decades of experience from both race and street performance. Wilwood XRS4R four-piston calipers, 13” or 14” two-piece rotors, and high-performance BP compound pads provide optimized and balanced braking to compliment front big brake upgrades on all types of custom, show and high-performance street machines.  

Modern computer FEA design and state-of-the-art precision CNC machining allow Wilwood’s new XRS calipers to convert stress-flow, premium-grade forged aluminum into a lighter design with more rigidity, allowing improved airflow and cooling for increased performance and control. The unique center X-bridge strengthens the caliper body without adding mass, resulting in a caliper of merely 4.5 pounds, up to a 15% weight reduction from its predecessor. XRS calipers retain internal fluid ports and two bleed screws to allow differential bore models to be used in either front or rear of spindle applications. Optimized profile high-temperature seals and stainless-steel pistons increase service life and reliability. Optional caliper finishes and rotor designs enable the builder to personalize the style and optimize brake performance for every individual application. Brake Kit does not include brake lines. Wilwood Flexline brake lines are necessary to complete the installation of the kit and must be ordered separately. See below for brake line kit options:  

• Wilwood 12" Flexline Brake Line Kit #WIL-220-17288. (Weld-on tabs for juncture between hard line and Flexline.)  
• Wilwood 12" Flexline Brake Line Kit #WIL-220-17289. (Bolt-on bracket for juncture between hard line and Flexline.)  

Some vehicles may require an extended rear parking brake cable for proper function, which is sold separately. Please use kit # WIL-330-9371  

*This Brake Kit may require 18-inch or larger wheels. Please refer to the wheel clearance diagram image or attached PDF to verify caliper clearance for your specific wheel.
