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.
