NEW RAM DUAL-DISC CLUTCH ASSEMBLY FOR THE 2011 MUSTANG GT 5.0

Written By Moore Good Ink Perhaps the greatest news for the 2011 Mustang GT was the introduction of the 5.0-liter modular engine and the switch from a Tremec to a Getrag 5-speed manual transmission. To that end, RAM now offers their Force 9.5 and Force 10.5 dual-disc high performance clutch assemblies, along with single-disc sets from HDX to Powergrip HD. In addition Ram has also made available new billet aluminum and steel flywheels for Ford’s new GT. These new parts mitigate pressure plate troubles at high engine speeds. Ram developed its 5.0-liter clutch packages because of an engagement problem that occurs on low-mileage, early-production 2011 GTs (built prior to April 25, 2010). Though the clutch disengages at high engine speeds, 6,000 rpm or more, centrifugal forces prevent it from re-engaging, unless engine speeds are reduced. As a result gear changes at high engine speeds are awkward if not impossible. RAM had already experienced similar centrifugal troubles with GM flat diaphragm clutches during the 60s and 70s, and they adapted a high-cone cover assembly for their new RAM Force dual-disc setup. This technique prevents the clutch cover fingers from traveling over center.  The RAM Force assembly provides a torque capacity of 800 lb-ft and comprises pressure plate, dual-clutch discs, Blanchard-ground steel floater plate between them, and an aluminum flywheel (the OEM flywheel cannot be re-used). In common with the other Force 9.5 dual-disc units, this assembly is compact and light, contributing to faster acceleration and deceleration. Moreover, it operates quietly, requires pedal pressure no greater than that of the OE part, and as with other Ram dual-disc assemblies, this unit...

RAM CLUTCH PROVIDES US WITH THE HIGH-RPM 'FIX' ON THIS 2011 MUSTANG GT

Race Pages December, 2010 Perhaps the greatest news for the 2011 Mustang GT is the introduction of the 5.0-liter modular “Coyote” engine but there was also a switch from a Tremec-sourced transmission to a Getrag 5-speed manual transmission. Unlike the Tremec, the Getrag employs a 23-spline input shaft, the same number of splines used on the old Pinto 4-speed. Meanwhile, Tremec is busy readying an aftermarket version with either a 10- or 26-spline input. Just like last year, the Shelby GT500 has exclusivity on the 26-spline Tremec 6060 double-overdrive transmission, and Mustang GT owners are left with the standard 5-speed box. But all is not rosy… Read the full...
