Organic Dual Disc Clutch for 7.3L Powerstroke

If you’re running a modified 7.3L Powerstroke and starting to feel your stock clutch struggle under the extra power, the Valair Organic Dual Disc Clutch is a smart next move. Built specifically for 1999–2003 Ford Super Duty trucks with the ZF6 transmission, this clutch kit is designed for trucks making serious power—up to 650 horsepower and 1300 ft-lbs of torque—without giving up daily drivability. What sets this clutch apart is its dual disc design paired with organic friction material. That combination offers a noticeable increase in holding power over a single disc setup, but with smoother engagement and a more forgiving pedal feel than more aggressive ceramic options. It's especially well-suited for street-driven trucks that see a mix of highway cruising, performance mods, and the occasional hard pull or light towing. The 3800 lb diaphragm-style pressure plate helps keep shifts snappy while keeping pedal effort just slightly above stock—so your left leg won’t hate you in traffic.

User-Friendly Design

This clutch is for the guy who’s turned up the power but still needs to rely on his truck every day. Whether you're hauling tools, chasing weekend horsepower goals, or just want something stronger and smoother than stock, Valair’s organic dual disc delivers a nice middle ground. It offers the confidence you need when you're putting the power down, without turning every shift into a chore. Clean install, great street manners, and enough strength to handle your build—this is the clutch that brings it all together.
