Features & Product Details

If you’re looking for one of the better bang for your buck performance upgrades, then you cannot go wrong with the Sway Bar Upgrade Package.  Even though the factory sway bars are efficient, you will have the option of choosing from a variety of fine sway bar replacements brought to you by some of the finest companies in the business.

This kit will come provided with the front and rear sway bars of your choice. Larger diameter sway bars are stiffer, and will provide better chassis stability under cornering and will relieve any major over steering and under steering issues you may have depending on your setup. Sway bars will prevent excessive rolling of the chassis under fast corners and provide an overall secure feeling with better performance which provides the driver with better feedback that makes for a better driving experience during a spirited drive, or on a weekend track event.

In addition to the sway bars, you will have the option of choosing the preferred set of front and rear end links for your vehicle.  It is common to know that over time, the factory end links can become weak after a certain mileage. This can affect handling or alignment issues, and there could also be other issues such as increases in noise and harshness.  Now you have the option of choosing from a variety of quality end links provided by some of the best manufacturers on the market. These end links are made from high-grade metals, and some will be adjustable to add pre-load to the sway bar.

In conclusion as amazing as your vehicle already handles coming out of the factory, why not add some extra sauce with quality parts that will provide a lifetime of performance. With the Sway Bar Upgrade package, you will have better control, feedback, and more confidence to push your vehicle further where you were otherwise limited with stock suspension. Everything will be provided including hardware to make for a ready installation.

  • Q: Are Perrin endlinks too long if vehicle is not lowered?  TheDapperGinger1 month ago

    The product description for the PERRIN end links states " These are also longer when compared to the OEM units. The extra length has been designed to maintain a good position for those with lowered vehicles." If my vehicle is at stock height, will these still fit properly, or will I need to go with whiteline or kartboi? Thanks

      A:  While you can make the Perrin end links work, you would be better off with the Whitline or Kartboy for stock height.
