Just-N-Time Button Knobs

Just-N-Time button knobs are adjustable, high performance transbrake buttons designed for drag racing to precisely control reaction times. These NHRA-accepted, hybrid-style buttons feature interchangeable color-coded springs and adjustable positions to offer over 100 different release speeds. They're designed for a positive feel with or without gloves and are used for transbrakes, line locks, or nitrous.

Key details:

* Maximum adjustability: The system uses 6 color-coded springs (Red is fastest, Black is slowest) and 4 different thickness spacers for tailored, consistent release speeds
* Models:
-- Original Just-N-Time: Features a 10-amp micro switch with a side-mounted spring
-- Just-N-Time XL: Uses a heavy-duty 20-amp micro switch with a top-mounted spring
* Versatility: The mushroom-style head provides a positive feel for drivers
* Replacement parts: Individual replacement knobs, springs, and switches are available for maintenance
* These buttons are designed to allow racers to tune their launch without relying solely on a delay box
