4003 upgrade kit makes 4003 into 4002

GFB’s Short Shift kits are like no other. Until you feel the action of one for yourself, you won t believe the difference!

Why did we bother to make a short shift kit, when there are so many other brands available? Because there was room for improvement!

Our unique system means that not only is the shift throw distance fully adjustable, it can be reduced more than any other brand by a long shot (at the shortest setting, the throw from 3rd to 4th is a mere 55mm, or 2.15 ), whilst retaining the stock gearstick height.If you want a race-car feel when you change gears, look no further than a GFB short shift kit, the shortest throw shifter on the market!
