does this add power to my V6? i understand that the v6 isnt the most powerful of stangs off the lot, ive gotten the cai, new 65mm throttle body, edis coil pack, flowmaster dual exhaust, 3.73 gears, and even 2inch lowering springs for my handling, will this add to my power of my v6? will i need to make any changes?

  • You will notice this more as take off power than raw hp increase. This allows equal distribution of power to both rear wheels on take off. No more one wheel peels with this baby, lay some proper rubber.

    THIS IS AWESOME!

    First off this is a must have. I cant get that stupid smile off of my face still. It puts down power more evenly and helps when your taking off as well, oh and the sweet two wheel burnouts! Its a great mod and a must have for ALL V6 owners! However it is a bit pricey, compared to the old ford one, which is not being made anymore. It is expensive but totally worth it! While your down there get a rebuild kit with everything you need in it! Overall, I am SUPER happy i got this! Thanks AM! Hope I helped everyone!

    completely changes the car's handling and makes it move through a turn. It's definitely an expensive unit but since it's good for more power than any sixer anywhere can make n/a, it will last a good long time and is worth it. This, paired with a nice set of gears will wake up anyone's six.

    V6 Stang LSD

    Absolutely love this product with the auburn LSD and the 4.10 Ford Racing gears makes a huge difference in the drivability of my car it squeezes every last horse out of your v6. You can feel the biggest diferance is right off the line, and between 3 grand and 5500 rpms. The description says it ands 5 hp but it feels close to 100. I would definitely recommend these two together to anyone with a v6 that's looking to put a little pep in its step. O best of all no more one wheel peels!!

    This product is a must for street or drag for Mustangs!

    We removed the stock gears and installed the 3.73 gears with Auburn Posi-Torque in four hours on an 02 Mustang. We renewed the rear brake pads at the same time. We also had to re burn the computer chip to obtain the correct speedometer reading. The total performance was noticed immediately with improved shifting through the automatic transmission. We highly recommend this product. Al Chornyi

    LSD

    This is one of the best upgrades I've done to my stang. I can feel the power being planted to the pavement. A little pricey but worth every penny.

    no more one wheel peel

    Having prior knowledge of a rear end, puttin this in with the 3.73 gears, my car definitely picks up much better! And with the two tire marks instead of one, this little sixer is definitely more fun to drive around! It is a must!

    Great for V6

    Got tired of havin' a one wheel wonder.. Did a ton of bolt ons to my V6 and decided to break the other tire loose for some extra power and nice burnouts. The car definitely handles differently and has an extra kick to it. It's a nice feeling to do a burnout and start sliding sideways and leaving two skidmarks instead of one.
