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.
IMPORTANT! VERIFY YOUR PCM and THROTTLE BODY MM SIZE needed in Drop down menue.
You must visulally check your PCM and count the pugs on it in order to confirm what PCM you have. It gets "GRAY" in the 2002-2003 years where you could have either one of the PCMS. You need to select either of the two options in the drop down menue in order to receive the correct throttle body.
JTEC PCM -(3-PLUG PCM)(1999-2003) - Small Idle Air Control
NGC PCM -(4-PLUG PCM)(2003-2007) Large Idle Air Control
BIGGER IS BETTER... But you need the ability to tune for the additional air flow. For this reason 72MM is only suggested if you have plans for custom tuning. If you do not plan custom tuning and only plan to use a SUPERCHIPS tune then 70MM is the largest suggested size that we recomend. With Superchips the 70MM will perform better then the 72MM. But with custom tuning the 72MM will out perform the 70MM.
The new Magnum 4.7L overhead
cam motor is a great design. For most light vehicles (Dakota, 2x4 Durango, 2x4 Ram 1500) the 70mm 4.7-00 TB is
the best choice. Due to the many different software revisions for these vehicles (2x4 Ram, Dakota Durango)
performance gains vary. The earliest 4.7s see the largest gains with increases of 7-11hp and 6-12ftlbs of torque on
a stock motor. The 68mm 4.7 TB works well for the heavier vehicles (4x4 Rams, 4x4Durango’s) and the 72mm 4.7
is for lighter vehicles looking for maximum gains. Motor modifications recommended for maximum gains from the
72mm 4.7 are: headers, cat back exhaust, high flow air intake, computer flash, factory HO or after market Cams. The
72mm 4.7 is ideal for factory HO motors.
Applications: 2000-2005 Stock to mildly modified 4.7L Overhead cam motor - 4x4 - 4x2
The 4.7 liter F&B throttle body series comes with all new stainless steel sensor hardware. This TB has a 4" inlet diameter and requires a 4" to 3.5/3.25" adapter to hook up to your stock resonator box. F&B has a 4"x3.5" dia. reinforced Silicone coupler available for this purpose. The F&B 70mm throttle body flows over 700 CFM @ 25"
1x72MM Applications: 2000-2003 Fully modified 4.7L Overhead cam motor - 4X2
The 4.7 liter F&B throttle body series comes with all new stainless steel sensor hardware. This TB has a 4" inlet diameter and requires a 4" to 3.5/3.25" adapter to hook up to your stock resonator box. F&B has a 4"x3.5" dia. reinforced Silicone coupler available for this purpose. The F&B 72mm flows 790 CFM @ 25".
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!
