Short Throw Shifter (STS) by IPSCO for Dodge Vipers 1992-2010
Short Throw Shifter 101:
The distance that the shifter has to move between gears is known as throw. A short throw shifter is designed to increase the speed of the shift by making the distance traveled shorter and by making the mechanical aspects of the shift smooth and effortless. A common misconception is that a short shifter is just a chopped off version of the stock shifter. In fact, chopping your shifter has no effect on the angle that your shifter shaft travels through between gears and therefore does not reduce the shifter's angular throw.
The IPSCO STS:
The IPSCO Short Throw Shifter (STS), is designed to reduce the distance your hand needs to move to engage the next gear, thus reducing the amount of time spent shifting, reducing wasted time between shifts, and resulting in improved performance. We have decreased throw by reducing the angle that the shifter shaft travels through during its stroke between gears. IPSCO's design changes the pivot point geometry of the short shifter from the stock factory shifter to reduce the distance that the upper section must travel to achieve the same degree of movement in the lower section where the shift rod engages. This ensures that although your hand is moving a shorter distance, the transmission is still fully engaged in every gear, and is carefully designed to create the optimal throw length, angular shift throw, and shift knob height. The design also includes springs to help users accurately move from gate to gate, to help prevent missed shifts and over revving of the engine on down shifts. The end result is a shorter, precise shift, which requires a shorter hand movement to engage the next gear, and looks and feels sportier.
Made out of 6061-T6 CNC machined billet aluminum, durable nylon pivot ball and stainless steel stem, with rubber boot. Springs included with this unit are designed for the performance minded driver. Direct bolt-in and will work with the stock factory knob and isolator, or an aftermarket shifter knob using 1/2-20 UNF threads, using one of IPSCO's 1" or 2" shaft lowering kits.
