GM Throttle Bodies

Granatelli Motor Sports GM throttle bodies are complete electronic drive-by-wire assemblies for GM LS and Gen V LT engines, from 95mm to 120mm, with the factory-style GM 6-pin connector. Pick by engine family and intake manifold opening, not by the biggest number.

Shop GM Throttle Bodies by Size

LS throttle bodies: LS 103mm | LS 105mm | LS 108mm | LS 112mm | LS 120mm

Gen V LT throttle bodies: LT 95mm | LT 103mm | LT 112mm

Built for boost: every Granatelli GM LS and LT throttle body, billet or cast, is rated for up to 35 psi.

A bigger throttle body adds power only when it was the restriction, so plan the intake, heads and tune together. A tune is required after installation. Made in the USA.
