 LS1 Throttle Body
Nitrous Express 
Nitrous Express LS1 Throttle Body
NX introduces "Next Generation Technology" 85mm throttle bodies for the LS1/LS6. Guaranteed not to stick or bind, this throttle body had a stainless steel throttle shaft riding on the highest quality sealed roller bearings and precision CNC manufacturing provides a perfect fit that does not allow the throttle blade to contact the throttle body throat. True 85mm knife edged throttle blades, flow improving CNC machined Vortex generators, counter sunk throttle shaft screws, and custom triple 10 million cycle return springs insures that this is the highest flowing, smoothest operating, throttle body on the market today. No OEM parts are reused in NX's throttle body, only the highest quality 6061 T-6 aluminum bodies, stainless steel hardware and black anodizing meet NX's stringent quality standards.

All units are designed as a direct-replacement, and require no other modifications.


F.A.S.T. Throttle Body 
Fast LS1 ThrottleBody

FAST used the latest modeling software and test equipment available to produce designs that yield the maximum flow per square inch of cross-sectional area.

All throttle bodies are machined from billet 6061-T6 aluminum on precision CNC machining equipment for consistent quality and light weight.

  • CNC machined from 6061-T6 billet aluminum
  • Brass throttle blades to contol vibration and reduce thermal expansion
  • Throttle shafts are machined to decrease their cross-sectional area, leading to increased flow
