Description

Converting your Mopar 5.7L Hemi from automatic to manual doesn't have to mean chasing down mismatched parts from a dozen vendors. This complete T56 Magnum package eliminates the guesswork by bundling every component you need for a bulletproof six-speed conversion - from bellhousing to driveshaft yoke. You choose the ratio set that matches your build goals, whether that's the 2.66 close ratio for aggressive street/strip driving or the 2.97 wide ratio for stronger low-end punch and relaxed highway cruising.

The TREMEC T56 Magnum is the aftermarket version of the TR-6060 found in factory muscle cars like the Dodge Challenger, Viper, and Chevrolet Camaro. It handles 700 lb-ft of torque thanks to substantially increased gear face widths, two-piece laser-beam welded gear construction for precise tooth geometry, and a bolstered one-piece countershaft that resists distortion far better than previous designs. The 26-spline input shaft includes generously long splines to accommodate twin-disc clutch setups, while triple cone synchronizers on gears 1-4 and double cone synchronizers on 5-6 and reverse deliver smooth, high-rpm shift capability.

The included isolator-type shifter reduces drivetrain noise and vibration transmitted into the cabin while maintaining the precise, communicative feel Magnums are known for. Built-in mid-shift provisions under the inspection cover allow for simple mid-shift conversions if your application requires it. Dual speedometer pickups - both mechanical and electronic - provide flexibility for gauge integration in classic and modern instrument clusters alike.

The Gen III Hemi shares the small block LA bellhousing pattern (minus one bolt at 12 o'clock), which this package addresses with the proper bellhousing, flywheel, and clutch combination. The full hydraulic release system eliminates mechanical linkage headaches, and you can select from multiple shift knob styles, lever options, and boot configurations to match your interior. Professional installation recommended due to ECU modifications, hydraulic system integration, and tunnel work typically required for proper fitment.
