Product Description

The Wilwood 220-8999 flexline brake hose kit offers a high-quality stainless steel braided rear brake hose designed specifically for GM 1500 and 2500 series trucks equipped with 13" rotors. This 10.00" flexline is engineered to replace or upgrade the factory rubber hose, delivering firmer brake pedal feel and reduced expansion under braking pressure - a benefit for both street and light performance uses. DOT-approved construction ensures compliance with standard road requirements.

Featuring -3 AN hose sizing, straight inlet and outlet fittings, and included adapters for chassis and caliper connections, the 220-8999 kit integrates with aftermarket disc brake setups and performance brake systems. While designed with GM full-size truck rear brakes in mind, always confirm length and fitting compatibility with your specific brake system and rotor size before installation.
