GFB Shifter Upgrade For # 4003
This kit turns the basic 4003 short shift kit into the 4002 complete pro shift kit.
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 GFB bother to make a short shift kit, when there are so many other brands available? Because there was room for improvement!
GFB's unique system means that not only is the shift throw distance fully adjustable, but it can also 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!
