    Driveshaft, Is it worth It?

    I have a 99 V6 so I have the one piece steel shaft, is it worth the 100 bucks (on average) to get a used LS1 aluminum driveshaft, I know on the older cars with the 2 piece driveshafts that would be an upgrade but what about stock steel vs. stock aluminum on a mostly stock V6 car?

    You are not really going to see a ton of benefit. You might see a little increase in throttle response due to the decrease in rotating mass, but not much else. I would say if you are taking your car a certain direction, drag, autocross, road race, then get it because any bit helps. Ultimately it is up to you, if you want it then buy it.

    Agreed ^ Another advantage is the ease of removing and installing if your doing any work on the car.

    unlike your 3.4 I already have the 0ne piece steel, so R&R is the same regardless of aluminum vs. steel for me, it's just the weight difference then mainly.

    as for the direction of the car, it is a Daily Driver that I am slowly building up using V8 parts anywhere I can so if the day where to come where I had the funds I could do a V8 swap.

    aluminum driveshaft was the best mod I did in the car...I felt I gained more out of the driveshaft swap alone compared to when I did my exhaust in the v6

    for the price you can find aluminum shafts for, it is worth every penny

    The weight difference when I weighed my steel shaft and aluminum shaft was 4lbs.

    The main reason thirdgen guys swap to an aluminum shaft is because the steel shaft is prone to becoming imbalanced over time.

    what where the weights to start with, with out a starting point I don't know if 4 lbs is a lot or very little weight difference. also I should note my stock steel shaft is at like 208k miles so if they are prone to becoming unbalanced with time then I would say that is quite a possibility with mine.

    I think the balancing problem comes mostly from developing rust etc... Aluminum shaft weighs 11 lbs iirc. I don't think it would be a noticeable difference from a steel shaft.

    Another thing to consider is that it has a larger diameter than a steel shaft. This could negate some of the effects of a lighter driveshaft

    In my 3rd gen it made a huge difference. Granted my steel driveshaft had only 65K or so miles on it so I didn't have a rust issue, but considering my car is being build as a road track car I could instantly feel the difference. I am very glad I made the switch.

    I like the driveshaft question. I just reply now with "is it worth it to wipe your ass with toilet paper?" It just is.

    For the $80 it cost to get one, yes an AL one is worth it. I think I paid $60 locally for mine and even got a second slip yoke

    You need a new scale because yours is broken, the aluminum is about 11lbs and the steel is twice that and almost about 25lbs

    when you are talking rotating mass, that is a huge difference...guys pay thousands of dollars for light weight rims that knock off 5-8lbs per rim.

    The reason some v8 guys stick to the steel is because at a certain power point you will shred the aluminum shaft and twist it up like a pop can- you won't have that issue in the v6, trust me.

    You must be talking about a two-piece driveshaft. There's no way the 3rd gen steel shaft weighs 25 lbs. Even going by feel you can tell the aluminum shaft is nowhere near half the weight.

    Also, my aluminum shaft weight matches yours, at 11 lbs. My stock steel one weighed about 15.
