The Centerforce Diesel Twin Clutch Kit, No. 04026651, was designed for 2005.5-2013 Cummins-equipped Rams with the G56 six-speed manual transmission. Two hub discs use spring-loaded bushings to aid smooth engagement. The primary springs help dampen engine vibration and transmission gear rattle, and the secondary springs absorb the shock and harmonics when the clutch is engaged. The floater is drilled and slotted like a brake rotor to dissipate heat. The patented ball-bearing pressure plate and centrifugal weights add the clamping force, giving the Diesel Twin a rated 1,700 ft/lbs holding capacity. The clutch features a single-mass flywheel, a pre-bled hydraulic slave and master cylinder, a starter spacer and an alignment tool.
