I don't think anyone here can make an accurate prediction of clutch strength.

Keep in mind though, that for the 2008 model year, the 6 speed and it's clutch were bolted to the 320+ HP / TQ upgraded 4.7L.

I think they are both big strong beasts.

 

i have a aftermarket clutch and flywheel.. but before i changed mine i still would launch my truck.. i even towed a double axle motor home up a hill with my v6 6 sspd standard and the clutch held.. truck is alittle stronger then some people give credit for.

 

Wow. That's pretty impressive.
Isn't the towing capacity on the 3.7L around 3800 or so?

 

Twink - what brand clutch and flywheel do you have?

I believe the tow ratings are low because :

1) The 6 speed rear axle ratios are pretty lousy
2) The output of the V6 is low
3) People can't drive, and there's a big liability associated with clutches and high tow ratings. Particularly on a truck without a true 'granny' gear.

If you are looking to spark up your ride, I would slap a set of 4.10's in the rear axle. For my Dakota, with a little less weight and smaller tires, I think 3.92 would be good, and 3.73 should have been standard from the factory. Oh well.

 

I actually read that the tow rating on the 3.7L was much better than the V8 and the Hemi.
On a side note I just scored a NOS 1 year only 67' 8 track player for my Beetle for SIXTY BUCKS!.... not sure who else to share my excitement with haha.

 

I think that if the 6 speed tranny can hold just over 300hp, and all of the trucks use the same auto trans, what if you slapped it on a hemi? Just a thought that crossed my mind a while back.

 

You either misread or read something that was incorrect. All there is to it.

A Hemi would bolt up to the 6 speed. There was a SEMA Jeep project that used our transmission with a stock 345 HP 5.7L.

300 HP would be conservative. I believe these transmissions are good to 400 HP.

But remember, HP is dependent on speed. I would *not* put this transmission behind a 400 HP Cummins.

It's much better to consider a transmission based on it's rated torque input.

Getrag does not list a model "238" on its website, but it does list a "6MTI520" with identical specs, such as ratio spread and synchronizer configuration. Rated input works out to 383 LB-FT.
