In designing the 7.25 series clutches, we put our extensive knowledge to work developing a more durable 7 ¼ inch clutch. A new internal drive design provides smooth, drivable engagement, using a four paddle disc design that has twice the friction material thickness of competing brands. The metallic friction material is our own proprietary mix known for its outstanding durability in our 6 ¼ Assault Weapon clutches. Clutch center hubs feature an 8 rivet pattern for added durability. A single disc version is available for classes that require a single disc clutch, but do not specify size or weight. The RAM 7.25 series clutches are built on a button flywheel that is compatible with most flex plates. To complete your installation, use a heavy duty RAM hydraulic release bearing.
90 Series components are used in all ‘Assault Weapon’ clutches utilizing the ‘bonded pad’ discs. New 90 and older 70 series discs do not interchange! For optimum clutch performance, RAM always recommends rebuilding the entire clutch.
RAM clutches for ‘stock rule’ classes are available in many configurations to meet your specific class rules. For Chevrolet applications, choose from several different weight pressure plates ranging from stock down to a scant 11.7 pounds. Disc choices include a sprung center organic, solid center organic, or six paddle metallic for the ultimate in durability. Lightweight flywheels are also available in 3 different weights. Mix and match these components to meet your specific rules or select a complete RAM system ready to install out of the box. Ford racers can also benefit from lightweight pressure plate and disc combinations, as well as 2000/2300 options in both 8.5 and 7 7/8 inch sizes.
