{"product_id":"brake-plumbing-residual-valve-kit","title":"Wilwood 2 lb Residual Valve Kit w\/ -3 AN Adapters \u0026 Hardware","description":"\u003cp\u003eThis brake system kit features (2) Wilwood 2 lb residual pressure valves, designed to maintain slight pressure in the brake lines to improve pedal feel and response. These valves help prevent fluid drain-back and reduce the amount of pedal travel required to engage the brakes—making them a must-have for custom brake setups, race cars, and off-road builds.\u003c\/p\u003e\n\u003cp\u003ePaired with -3 AN to 1\/8\" NPT adapters, tube nuts, and sleeves, this kit makes it easy to integrate into your brake system with clean, reliable plumbing. Whether you're building a new system or upgrading an existing one, this complete package provides everything needed for proper installation and consistent braking
