Wilwood 260-8420 Adjustable Proportioning Valve - 6-Position Lever

The Wilwood 260-8420 is a precision-engineered adjustable proportioning valve designed for racing and high-performance brake systems. Featuring a forged billet aluminum body for maximum strength and minimal weight, this valve allows drivers to fine-tune brake bias on the fly with six distinct preset adjustment points.

Key Features:

• Six-position lever adjustment with positive click detents for quick, precise brake bias changes
• Pressure adjustment range from 150-1200 PSI with up to 57% line pressure reduction capability
• Forged billet construction for exceptional strength and durability
• Compact, lightweight design at only 6.1 ounces
• 1/8-27 NPT inlet and outlet ports for versatile plumbing options
• Two 0.25-inch side mounting holes spaced 1.00 inch apart for secure installation
• Includes two 1/8-27 NPT to 3/8-24 inverted flare female fittings for 3/16-inch hard brake lines

This proportioning valve is ideal for racers who need to adjust rear brake pressure between runs or even during competition. The tactile click mechanism ensures you know exactly which position is selected, eliminating guesswork when making critical brake balance adjustments. The valve installs inline in the rear brake circuit to reduce pressure to the rear brakes, helping prevent premature rear wheel lockup and improving overall braking performance and vehicle control.
