The F&B Throttle Bodies Product Line
F&B Performance Engineered Products stocks throttle bodies for 1992-2003 Magnum engines, Dodge/Jeep V8 and V6,
Jeep 4.0L and Viper V10. See below for a full description of each. Currently we have distributors
around the country, and we also take factory direct orders.
All F&B products are CNC machined from the
highest quality raw materials
Body material is 6061-T6 aluminum with a clear sulfuric anodized coating. F&B shafts are machined from
17-4PH stainless steel or moly-coated 303 stainless steel. F&B butterfly plates are made from 6061-T651 aluminum
or aluminum bronze, depending on the application. All bearings are high-speed ABEC 3 ball bearings with high temperature
grease.
You need to enlarge the bore to get the big
flow numbers
Most stock throttle bodies are manufactured from aluminum castings. Once the casting is machined, thin walls,
porosity, and/or casting defects compromise the throttle body’s integrity. This is where high-quality billet
aluminum comes in, while F&B throttle bodies flow more than any other throttle body with the same bore size.
F&B's 6061-T6 billet TB can handle the thin-wall sections required for big flow rates in the stock throttle
body mounting patterns. Bore distortion, pulled threads, and cracked walls are eliminated, because we start with
billet! Check out the product pictures and descriptions. An F&B throttle body not only looks like a gem, it's
also bulletproof! With F&B products, making power and looking good go hand in hand!
