2x58 Ported Throttle Body 1992-03 Stroked 5.2L & 5.9L V8 Magnum

The F&B 58mm throttle body features a radically profiled 17-4 PH stainless steel shaft for maximum flow and 58mm equivalent plates. The offset blades with angled profiling provides maximum tip in control with added vacuum assist closing. This TB flows the equivalent of two 58mm bores, over 1200 CFM at 25". 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 airhat. The manifold opening and factory gasket must be radically enlarged for this throttle body. We recommend the use of a MPI 4 bbl w/2 bbl adapter or the MPI 2 bbl manifold from Mopar Performance to optimize your setup. No modifications are required for most aftermarket air inlet systems This TB is for stroked motors over 360 ci displacement only!

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, it's also bulletproof! With F&B products, making power and looking good go hand in hand!
