4.0 SOHC Flywheel

[Silas Mc]

I live in an area with lots of hills, low speeds, dirt roads and steep driveways. I have a 2006 Ext. Cab with the 4.0 SOHC. I usually have tools in my bed and tow a 5x8 trailer with tools and parts for work. Im going to need to put in a new clutch sooner than I'd like but I'm curious if anyone knows of heavier flywheels for these engines? It might be a marginal improvement for backing into inclined driveways and stop and go's while towing. If I don't see a "performance" gain it will definitely be more forgiving on the new clutch.

I see a company that makes one for the Toyota 4.0 v6. Don't see one for the Ford. In the description of the toyota they say it helps in stop and go and when oversize tires are used. That tells me if you used smaller diameter tires or raised the numbers in the ratio of your gearing, you would achieve the same result.

I can vision putting on smaller tires but I don't think I would like how goofy it would look. Haha. I thought about different gears too but I think I would lose much more MPG and top end speed. So I suppose its how much trade off I would want...
As far as I know a heavier flywheel does not have significant fuel mileage changes. I wonder if a machine shop can add weight?

not sure a 4.0 needs it, but you can have it done.

not overly cheap, but for the intended use it will be noticable.
