Re: Towing jeep--need power
Can't answer the "is it possible" questions...That said, I would worry only about the tranny. Make sure you keep it in a low enough gear that the Torque Converter locks up...you don't wanna have 300+ horsepower slipping the tranny, uphill, with a wholelotta jeep and trailer behind. The next thing I'd worry about would be the rear axle. The biggest killer there will be heat. It puts a lot of stress on the gears to be towing a heavy load with a lot of horsepower, and I'm not sure what kind of rear axle those have in 'em. A good friend of mine was towing a 30' bumper tow house trailer with a 1500 sub with a 350...it had plenty of power for it, and when locked out of OD, the tranny behaved, but he burned up a rear end in 2500 miles. (Oh, and besides running the tranny low enough to keep it locked, (this next part is hearsay), I've heard that you need to keep it spinning fast enough to keep the fluid pumping through it fast enough to dissapate heat...but as I say, I'm not sure about that). As far as u-joints and such go, they tend to be more susceptible to sudden applications of torque and power than they are to more extended applications...Rolling down the highway at 70 and then leaning on the motor a bit to climb a hill doesn't worry me much. But starting out at a stoplight or tollbooth and gunning it...that's where you'll drop the driveshaft. Use a good quality synthetic extreme temp grease in the u-joints (and I'm a sucker for greasable u-joints rather than sealed for life on vehicles that see highway miles), and forget about 'em.
