What is a proportioning valve used for?

A proportioning valve is used to control the distribution of brake fluid pressure between the front and rear wheels. It helps prevent the rear wheels from locking up before the front wheels during hard braking, especially after modifications like rear disc brake conversions or when changing tire compounds.

What size are the fittings on this Wilwood proportioning valve?

This Wilwood proportioning valve uses 3/8-24 inverted flare fittings for both the inlet and outlet ports. This is a common size for many brake line applications.

Does this valve come with everything needed for installation?

The Wilwood 260-17117 proportioning valve includes the valve itself and a mounting bracket. You will need to supply your own brake lines and fittings that match the 3/8-24 inverted flare size.
