It comes with a new factory gasket, all new 18-8 stainless steel cap screws for your factory sensors, stainless steel hold down bolts, and the F&B billet seal nut with Renzoni bridge mount for your air hat. This TB requires minor modifications to your factory air hat (Ram or Dakota). No modifications are required for aftermarket air inlet systems. The 52mm F&B throttle body flow 860 CFM @ 25". Recommended for 295-400 crank hp applications.

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. F&B butterfly plates are made from 6061-T651 aluminum. 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, but it's also bulletproof! With F&B products, making power and looking good go hand in hand!

Perfect for hefty 5.2l (318cu in) builds and mild 5.9l (360cu in) builds up to 375hp.

Flows over 775 cubic feet per minute (cfm) flow rate. Your go-to throttle body to match your basic mods.
