Due to the slop of the internals in the transmission, there is an unacceptable amount of horizontal slop within the 1st and 2nd gear shift gates. What should be little to no movement ends up being nearly 1.0 inch of play. This makes for an unnatural placement of shift gates and a lost feeling of which gear you are in. The PERRIN shifter stop removes this play, reducing the horizontal movement to 0.12 inches. This makes for a solid connection between the driver and transmision.
The PERRIN Shifter stop is perfectly designed to bolt directly to the shifter. Being Constructed from 6061-T6 Aluminum allows for countless downshift from 3rd to 2nd gear without worry of damaging the shifter stop or shifter.
