TR6060 8 Bolt Crank

A 6-speed manual transmission tailored for increased torque output
 
A higher-torque-capacity version of the TR6060 6-speed manual transmission, the MG9 TR6060 is engineered to be a direct fit with Chevrolet Performance LSA and LSX454 crate engines with 8-bolt crankshaft flange. Used in the Cadillac CTS-V Series, it’s capable of handling an impressive 551 lb-ft of torque, making it the perfect transmission for your high-performance racer or muscle car.  
 
Featuring a combination of double-cone and triple-cone synchronizers on all gears, antifriction ball struts, fine-pitch splines, and a spring-loaded antifriction roller, the MG9 TR6060 is tailor-made to handle tremendous torque output.
 
Like the all-new T56 Super Magnum 6-speed manual transmission, the MG9 TR6060 is equipped with a 26-spline input shaft. Additionally, the MG9 TR6060 has reduced fore and aft shift travel and narrow synchronizer hubs, which allow greater face width on all gears.
