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 to handle torque capacity to roughly 1100-foot pounds 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.
RAM Street Dual disc systems are specifically engineered for today's late model performance cars and engine swaps into earlier vehicles. The purpose of these clutches is to provide smooth driveability for high power levels that was previously not available using aggressive friction material single disc clutches. Friction material is not the only consideration for good driveability. We also need to maintain enough overall weight in the clutch assembly so that the clutch can be driven at lower RPM and maintain vehicle inertia without 'bucking'. If the clutch assembly is built too light, driveability on the low-end suffers. Applications with large camshaft profiles are prone to this and need the inertia of a heavier unit if the owner wants to maintain this low speed driveability. On the other hand, drivers of road-race inspired vehicles will benefit from the lighter weight of a smaller diameter clutch as it allows the vehicle to drive deeper into the turns before letting off the throttle, and accelerate back to torque range quicker coming out of the turns.
Most RAM Street Dual systems are engineered for proper fit with late model hydraulic release systems. The setup height of the clutch is critical to proper operation; this eliminates the need for spacers or other modifications to the release mechanism. Dual disc clutches that bolt to a stock flywheel can be a release problem! Most every RAM dual disc works with the factory release system; the few that do not will function correctly by adding a RAM internal hydraulic bearing. So keep in mind, the smallest and lightest clutch assembly may not be right for your particular application. Depend on a clutch company that properly engineers their clutch systems to fit your particular vehicle.
