Street Dual Disc Clutches
The next generation of diaphragm clutch systems are here! RAM’s new billet diaphragm pressure plate anchors a complete offering of dual disc clutch systems with a driver friendly static pressure load of 2500 pounds, in both organic and metallic versions. The low profile cover design makes fit in tight confines possible, and configurable lever angles and build heights offer endless possibilities for custom fitment. A billet steel pressure ring and bolt in diaphragm spring make the clutch completely user serviceable in the field. As with all RAM street dual disc systems, street driveability is foremost in design. Pro Street systems utilize a strap driven floater plate for quiet operation. This is just a sampling of applications that are available – any unit listed in Force 10.5 is also available in Pro Street by changing the prefix from ’80-‘ to ’60-‘.
RAM’s Concept 10.5 clutch system bolts to your existing flat steel or aluminum flywheel. 10.5 pressure plate has a higher clampload than other modular units plus a larger disc surface areas are better able dissipate heat and handle load. Smooth engagement and light pedal effort, with strapped floater plate for quiet operation. Order by make, ring gear and input spline size.
The RAM Force 9.5 is the ideal entry level dual disc clutch for street use. With torque capacity to roughly 700-foot pounds and a moderate clamp pressure, it will handle small blower or turbo installations and provide a light pedal effort similar to the stock clutch. In fact, drivers of our 2010 Camaro test vehicle were not able to tell that the stock clutch was changed at all! The floater plate is driven from three sets of straps that eliminate any floater plate rattle at idle. The top clutch disc features a sprung hub assembly that absorbs the initial engagement of the clutch and reduces the chance of chatter on takeoff. This clutch is compatible with factory hydraulic release mechanisms except as noted in the application guide. It is compatible with all factory master cylinder systems when used in conjunction with a RAM hydraulic release bearing.
For higher horsepower applications, the Force 10.5 dual disc is the natural choice. Based on the design of the original RAM Street Dual, Force 10.5 is more street friendly by using a three strap system to locate the floater plate. This eliminates floater plate ‘rattle’ that is common on stand driven dual disc clutches. A high clamp load pressure plate assures plenty of holding power without excessive pedal pressure. Steel backed 300 series facing mean smooth engagement on takeoff and insure long service life. For higher torque capacities, the Force 10.5N features the proven RAM 900 series metallic facings. Force 10.5 dual disc systems handle bigger torque loads and are a bit heavier than their smaller cousins. This higher inertia translates into better low speed driveability in heavier vehicles, or in large camshaft profile applications. If you are bolting on a larger blower or turbo system, Force 10.5 may be the best choice for you.
The RAM RTrack Dual is modeled after our highly successful drag racing clutches used in high horsepower Pro Stock and Pro Modified applications. The major difference between these clutches and the Force 10.5 is the floater drive system. RTrack Dual uses a stand driven floater plate, which provides higher torque capacity and negative load capacity for vehicles that see more use at the track. It uses a 2400 pound clamp load pressure plate for good holding power without excessive pedal effort, and features 300 series sprung hub top disc and solid hub bottom disc for smooth engagement. A 900 series disc version is available for higher torque load applications up to about 1300 foot pounds. Expect some floater plate noise at idle with this unit’s drive system. If you need the ultimate in holding power and durability for street or strip, the RTrack Dual is for you!
