Quaife has long produced some of the finest racing gearboxes in the industry. Recently, Quaife has turned their attention to racing simulation and has adapted their craft to suit it. Other simulation shifters lack the proper mass behind them, or rather, underneath them to truly feel like gears are being shifted.This pro sim H shifter uniquely accomplishes this by incorporating a massive shifting linkage. This is what gives this Quaife sim shifter its heft. When you pull the handle on this pro sim H shifter, you aren't simply moving a stick from one spot to another, you are moving an entire shifter linkage just like there would be in an actual gearbox.
