EZ-Plate System restrictor plate Removal and replacement
The secret to index racing is just a few simple steps away!

With the EZ-Plate System installed, adjusting your E.T. is as simple as sliding in a different restrictor plate!

Specifically designed for Index, Open Comp, and Super class drag racing, EZ-Plate Systems under-carb restrictor plate takes the guesswork out of running your index, and enables you to easily set up your race vehicle to run your desired E.T. If you're not running the EZ-Plate System, you're not doing all you can to win!

Quickly Change Restrictor Plates and Adjust Your ETOnce the EZ-Plate System is installed, there's no need to remove the carb to change plates! Swapping to a different size restrictor plate is a 20 to 30 second job you can do even in the staging lanes.
