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.
BBK's new 80mm performance throttle bodies are a proven and simple way to bolt-on 8-12 horsepower in just minutes. Built from CNC-machined 356-T6 Aluminum Alloy, these new LS-1/Vortech Throttle Bodies offer the ultimate in Quality, fit, and finish. All units are designed as a direct-replacement, and require no other modifications.
