141125 | Rear Sway Bar Bushings 21mm | Nissan 350Z 2003-2009

Soft Rubber = More Body Roll

The rear sway bar of your Nissan 350Z or Infiniti G35 connects the rear wheels so that during a turn the body of your car doesn't roll to the outside and possibly cause a loss of traction. That said when the sway bar is being held in place by flexy rubber bushings the bar can move and cause the alignment of the rear wheels to change in a sharp turn. This can contribute to more frequent tire replacements because of uneven wear or allow your 350Z or G35 to slide out during a turn. When powering through turns on back roads here in Stephenville, Texas we like to know we will have traction.

Since a rubber bushing's primary function is to absorb vibration they are a good option in many bushing positions, but the sway bar doesn't transfer vibration because it doesn't support the vehicle's weight. This means you can use a firmer material without the normal increase in noise and vibration that accompanies polyurethane bushings.

Upgrade Your Sway Bar For Less

Prothane's 21mm Rear Sway Bar Bushings are made of polyurethane which doesn't flex like rubber and does a much better job of holding the rear sway bar. With the added grip of these polyurethane bushings, the stock sway bar on your 350Z or G35 will take on the characteristics of a more expensive, larger diameter sway bar. This will decrease body roll and keep the contact patch of your rear wheels flat on the ground to provide better traction and even tire wear.

As we mentioned before, there is really no benefit to rubber bushings since vibration will not be passed to the driver through the sway bar. As a bonus, polyurethane is much more durable than rubber, meaning these bushings not only provide a performance enhancement but they will outlast rubber bushings every time. In fact, Prothane covers these bushings with a lifetime warranty that DST will handle for you in-house.
