Big Mouth HEMI 87mm Throttle Body
SKU: F003 54088
Easy — 1–2 hours
Description
Part #: 54088
These throttle bodies offer increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those used in boosted applications. A smoother operating offset blade pivot improves throttle response, while a beefed up linkage and dual throttle spring mechanism ensure total throttle control. Constructed from billet aluminum, the FAST Big Mouth LT for Ford Coyote and Chrysler Hemi applications are new and improved versions of the original Big Mouth Throttle Body. With an 87mm throttle bore for the Ford Coyote and Chrysler HEMI, each one features a black-wrinkle powder coating and all of the same features as the original.
Our Big Mouth 87mm Throttle Body for Chrysler HEMI features a black wrinkle powder coating finish along with an improved throttle blade and pivot. In addition, our throttle body improves throttle response and eliminates blade deflection.
