Product Description

The Wilwood 260-8419 adjustable proportioning valve with knob control is a universal brake system component that lets installers fine-tune front-to-rear hydraulic pressure balance. With easy-to-use knob adjustment and precision internal metering, this valve gives enthusiasts greater control over brake bias - especially important in custom or performance applications where factory proportioning isn't optimal. The compact, black anodized body resists corrosion and fits in tight spaces during installation.

Featuring 3/8-24 inverted flare inlet and outlet ports, the 260-8419 interfaces easily with common brake line fittings and can be used in both manual and booster-assisted brake circuits. While not specific to any year/make/model, this valve is ideal for custom chassis builds, street performance cars, drag racers, and vintage restorations that require adjustable brake bias tuning to match unique brake component combinations. Installation hardware is included for straightforward mounting in a variety of configurations.
