Compact Design Designed, tested and built specifically for the aftermarket

TKX 5-Speed Manual Transmission Features and Benefits • Capable of engine speeds of 8,000 RPMs with shifts at 7,500 RPMs. • Designed for multiple applications with three shifter locations. Compact, end-loaded design provides clearance in most transmission tunnels without floor modifications. • Increased case strength with three-piece aluminum housing provides outstanding structural stiffness (includes main case, intermediate plate and rear extension). Gaskets at all flanges simplifies installation and eliminates fluid leaks. • Superior shift-ability through use of multi-cone synchronizers and hybrid synchronizer rings made of sintered bronze and carbon. • Noise, vibration and harshness (NVH) minimized with gear layout to best control stress levels. All gears supported by caged needle bearings to reduce end play on the gears. • All gears and shafts made from special grade steel (ASTM 4615) providing increased torque carrying capacity. • Equipped with a high-performance short-throw billet aluminum shifter that isolates road noise, while providing clean, crisp shifts. • Robust design with internal three-rail shift system and steel shift forks. • Wide gear width increases gear life and torque capacity. • Built-in reverse light switch and cruise control safety switch.

Tech Specs: 26-spline input shaft. 31 spline output. All gears and shafts made from special grade steel (ASTM 4615) 600ft-lb Constant Load Rated
