About this item

Upgrading your LS engine truck’s throttle body? This adapter gasket lets you mount a 4-bolt throttle body onto a 3-bolt intake manifold – no hassle. Made from aviation-grade aluminum alloy, it’s strong, corrosion-resistant, and built to handle heat and pressure. The inside is machined with a 3D taper that smooths airflow from 3.6 inches up to 4 inches, so you get max performance. Comes with everything you need: the adapter, two gaskets, and seven screws. Installation’s pretty straightforward – just bolt it in between your intake and throttle body. Fits most LS-based trucks (note: doesn’t work with Edelbrock Pro-Flo intakes). Part number 551597. Whether you’re adding a bigger throttle body for more power or just replacing a worn part, this adapter makes the swap clean and secure.
