Smeding Performance billet throttle bodies are packed with race ready features! They come standard with sealed stainless bearing shafts, precision fit throttle blades, and support standard GM IAC & TPS sensors. They also feature a beveled entry way that promotes air speed across the blade at low TPS values. This greatly aids in drivability when running a very large camshaft with a high flow induction system.

Includes stainless hardware for IAC & TPS.

Requires IAC #17113598 & TPS #17123852.
