This Mace Torque-Lock limited slip differential (LSD) uses a sophisticated design to provide a quiet, automatic splitting of torque. It performs like an open differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant.

The advantage of the limited-slip differential design is apparent when comparing it to the standard or "open" diff. In vehicles with this older style ofdiff when one wheel began to slip or lose contact with the ground the slipping or non-contacting wheel would still receive the majority of the power whilst the contacting wheel remains stationary with the ground.

This issue is completely resolved with the Torque-Lock LSD. Harnessing a similar configuration to the Harrop and Eaton Truetracs, the automatic torque biasing design makes it the perfect limited slip differential upgrade for any enthusiast that will be using their vehicle for either straight-line drag, circuit, off-road or tough street work.

The proven helical gear technology found in the Torque-Lock LSD eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its durability, but its smooth and quiet operation as well. The low cost and effective operation all make the Mace limited slip differential the ideal choice for performance vehicles.

Finally, a good night's sleep.
For almost a year, I've had sleep issues. No problem falling asleep, but I'd wake up 3 hours later and be up for the next 2-3 hours. I'd finally fall back asleep just a bit before the alarm and spend the rest of the day in a fog. It didn't matter whether I went to bed at 8:30 pm or 11pm - I was still up by 1:30-2 and awake for hours. It gradually got worse and I got desperate. A friend recommended Melatonin and I resisted at first, having tried it after our daughter was born (almost 15 years ago). The tablets I took then had some odd side effects and I only took them for a few weeks before throwing the bottle away. Now, I think I have have been taking far too high of a dose, because these 3mg tablets work great. Be careful when you take them! I'm awake and alert for about 20 minutes and then zone out totally - even in the middle of a conversation. After a couple of months, I've learned to just lay a tablet on my nightstand and take it when I'm ready to turn out the light. It works great: cured the problem of middle of the night sleeplessness. I still wake up sometimes at night, but have no trouble dropping back off to sleep. And when I wake up in the morning, I'm alert, energetic, and not already counting the hours until I can go back to bed to get a good night's sleep. For me, this supplement would have been a good buy at twice the price - and my family agrees. I'm rested, cheerful, and so happy I gave it a try. So far, no bad side effects. In fact, no side effects at all. I am taking it daily, but considering trying it on a more limited basis because of concerns about long-term effects. Considering, but haven't done it yet because I'm so enjoying a good night's sleep that I'm afraid to tinker with success! Although I saw results the very first night I took this, I waited to write a review just in case it was a placebo effect at work. But it's been 11 weeks and I'm confident that this product is really effective for me.

Time release.. ONLY way to go
Used this brand before... when refill needed, came back for more. Time release is the best way to go as it works all night. Not one big hit when you 1st go to sleep... A nice "hit"... to get you to sleep and then a slow release of the rest, to KEEP you asleep... Don't think you'll be disappointed. I use sustained release with any vitamin/supplement I take (assuming the company makes it) .. including this. It's the best way to allow your body to utilize the product.

A subtle sleep enhancer.
Melatonin, in my experience, is a very subtle drug. I took it for about a month and then stopped before I actually saw what it was doing. It allowed me to fall asleep quicker and when I woke up during the night, to fall back asleep quicker as well. No more tossing and turning. I prefer the timed release version since I tend to sleep about 4-5 hours straight and then wake up sporadically after that. I had been buying the timed release from GNC but this brand is much cheaper, more pills, and just as effective. I've also tried popping another one after that initial 4-5 stretch of sleep to further prolong sleepy time, but I don't know how effective that is. It doesn't put you to sleep, so there's no grogginess when you wake up. It just jump starts the natural process.

Time release is the best way
I like these time released tablets. Time release is surprisingly hard to find unlike the immediate release style tablets. Time release allows for a longer sleep pattern as it enters the blood stream slowly over time allowing it to stay in you system. Immediate release will hit you hard and fast but your body will metabolize within a couple of hrs leaving you without the melatonin in you system. I took off a star for being pricey, but these do work very well.
