2008 and newer 4.7 Underdrive crank pulley?

[JohnHenry]

As title reads, I am curious if anyone can point out a smaller diameter and/or lighter crank pulley (underdrive single crank pulley or kit) available for the 08' or newer 4.7 engines? I have looked at a few places and no luck. Is there maybe another vehicle that uses a crank pulley matching my request that will slip right on and fasten to the 4.7? Any info is appreciated, thank you.

I think ATI has a 25% Damper for your engine.

Price for this one is $414. Before commitment, does anyone know of any others available any cheaper elsewhere?

I assume this is one and only at this time, if I find anything else ever in the future, Ill post up here, but for some of the CAI kit prices vs. this under drive pulley, can't go wrong. I think 25% less drag is an awesome reward for the price. Hoping in casual and moderate driving habits a few or couple more mpg and a few hp gained overall.

Ill would do 4.56s before u/d for that price.

Gears because I tow are a considerable swap. With 3.92's my Rig at 70mph on the highway with no or low wind will settle around 1900 rpm's. Just worried because I travel the highway a lot about the best gas mileage.
