After upgrading the puny OEM rear sway bar to an ALTA rear sway bar, you will immediately notice a reduction in body roll when cornering, allowing for more of the tire to grip the road.


ALTA Sway Bars are made from solid steel using the latest precision bending equipment. The entire bar is powdercoated to fight corrosion and give it a deep red finish. We laser cut and MIG weld our bar ends for precise placement. This type of bar end far superior to many other methods and gives us greater precision over competitors. Some competitors simply smash the ends of their bars flat. This not only looks unattractive but also compromises the bar's integrity!


ALTA Rear Adjustable Sway Bars incorporate multiple endlink mounting holes which allow the installer to custom tailor your driving experience. ALTA Sway Bars increase stiffness by a minimum of 100% over the stock bar. By adjusting the endlink mounting position you can increase that stiffness to as much at 400% over stock. *varies by model. See the Specifications Tab above for more detailed information.

Centering Rings

ALTA Sway Bars feature centering rings that prevent sway bar movement in hard cornering. This keeps your sway bar centered and ready for the next corner.


All sway bars include polyurethane bushings for a crisp response and better turn in. Special pockets are carved into the bushing surfaces to capture grease and extends the interval between re-greasing.

Hollow vs Solid Bar

Competitive manufacturers of hollow bars will attempt to argue that the weight reduction they offer is a huge advantage over solid bars and is worth the significant price increase. Realistically, for a daily driver the difference in weight is unnoticeable. The difference between most aftermarket sway bars, hollow and solid, is only 2 lbs!

Welded or Smashed Bar Ends

ALTA uses a precision laser to cut the multi-point sway bar ends from plate steel. Using a jig, we weld them onto our bars in the exact location for best articulation and leverage angles. Competitors who cheaply smash their bar ends in a press (same way the factory saves money) and simply drill holes for endlink mounts will try to convince consumers that laser cut steel and precision welding is somehow inferior and inexpensive. It just doesn't make sense.


A sway bar is an automobile suspension device. It connects opposite (left/right) wheels together through short lever arms linked by a torsion spring. A sway bar increases the suspension's roll stiffness, its resistance to roll-in turns, independent of its spring rate in the vertical direction.

Care Instructions

If you live in a state with harsh winters, you are probably familiar with how salt is used to melt snow/ice on the road. While this helps keep roads safe for driving, it can also be incredibly damaging to your aftermarket exterior parts. Here are a few tips for taking care of your vehicle when it's exposed to salted roads.

  • Wash your car regularly to remove salt and prevent it from causing damage.
  • Check under the car for salt accumulation that can cause rust and other damage.
  • Use rust inhibitors that can be sprayed on the undercarriage of your car. Waterproof bearing grease is a great way to keep out water and dirt.

This product is susceptible to corrosion and noise created as this product wears and/or failures because of poor care is not covered under the warranty. By following these tips, you can help protect your new performance parts from the harsh effects of salted roads. Remember to wash your car, use rust inhibitors, and check regularly to protect from rust and other damage.
