When you're in a car going around a sharp corner or approaching a less sharp corner at a high speed, momentum dictates you will feel your body pulled toward the outside of the corner (or in the opposite direction you're turning); this is due to the same force pulling on you and the car and reaching equilibrium.  For example, let's assume we are headed around a right hand corner. As you're pulled to your left side of the car the vehicle's mass is also being pulled to the left, causing the suspension on the left hand side of the car to be compressed downward and yielding a lift on the right.  Combine this normal phenomenon with the right conditions including enough momentum and grip (or lack thereof) and add in extraneous factors like a vehicle with a high center of gravity, and the end result can be a rollover - not good, and this is called "body roll."

As you've surely surmised by now the greatest benefit of a TRD Rear Sway Bar is improved handling.  By keeping body roll to a minimum the weight of your Tundra Limited or Tundra Platinum is spread out more evenly across all four tires, giving a Tundra driver the desired enhancement in overall grip while cornering and allowing for much more responsive steering.  No matter what road your driving your Tundra Platinum or Tundra Limited on or across, a TRD Rear Sway Bar upgrade is a surefire way of improving the experience.

The TRD Rear Sway Bar works similarly to any other anti-sway bar, however it is custom made by Toyota Motors for your Tundra truck.  By transmitting force from the suspension on one side of the car to the suspension on the other side, the suspension's compression is lessened and acts to level the car out.

So why buy a genuine Toyota rear sway bar?  Just like anything else, non-genuine products are not only not made for your Tundra Limited and/or Tundra Platinum, but they also may not be made to your Tundra Platinum's specifications.  It is, of course, possible to have too much of a good thing in the case of anti-sway bars. If the bar is too stiff you can lose the independence of the two wheels you're connecting. In this case if you hit a bump with the right side of the car that will also be transmitted to the left side. Having too much anti-roll bar can result in the vehicle being unstable on rough roads and can have a profound, but negative, effect on control. This also holds true with extreme off-roading, where you want each wheel to be able to move as independently as possible to maintain traction while clearing large obstacles. Things like sway bar quick dis-connects, which allow you to quickly dis-connect the anti-sway bar without having to remove it, exist for people who want the maximum in off road capability without losing the road manners gained with this part.
