“The TERMINATOR button is the smoothest, most consistent, and most reliable bottom bulb transbrake button on the market.” 

– Peter Biondo


Designed by the Biondo Racing Family, the “Terminator” was specifically built around the new NHRA Super Stock, Comp Eliminator, and bottom bulb bracket race rules for the maximum allowed travel (3″) and adjustability. This button will consistently slow you down up to 4.5 hundredths (.045). The included shims can be easily added or removed making it easy for you to close in on your reaction time! See below if you want to order extra shims or a spare spring in our #TERM-KIT.

Button measures 5-5/8″ long, and the body is 1-1/2″ wide.

Button has tapped mounting holes on the bottom and side of the button. Can be easily mounted utilizing those holes.

EXCLUSIVE features found only on the TERMINATOR:

  • Shaft is made from high quality aluminum for maximum smoothness and consistency.
  • Internal spring eliminates chances of the spring getting caught or binding.
  • Free Tip sheet written by Sal and Peter Biondo included with each button. They will tell you precisely what each shim is worth (and much more!) … taking the guesswork out of adjusting your reaction time.People who buy this part also buy a 2 Lead Stretch Cord or a 3 Lead Stretch Cord
