STILLEN 2008-2013 Altima Coupe / 2007-2012 Altima Sedan Rear Sway Bar w/End Links - 304236

The STILLEN Rear Sway Bar with End Links for the 2008–2013 Nissan Altima Coupe and 2007–2012 Nissan Altima Sedan is a complete redesigned solution that fixes a well-known factory flaw while significantly improving handling and chassis stability.

From the factory, many Nissan Altima rear sway bars are prone to failure due to poor design. Instead of twisting under suspension load—as a sway bar should—the OEM bar is forced upward into the wheel well, causing it to bend in the center and eventually break. After extensive analysis, the STILLEN R&D team identified the root cause and engineered a completely new sway bar geometry that applies proper torsional load, allowing the bar to twist correctly under suspension travel.

Constructed from high-strength aircraft-grade steel, the STILLEN rear sway bar maximizes durability and torsional rigidity. The bar measures 0.750 inches in diameter and is non-adjustable, offering a perfectly balanced upgrade for street-driven Altimas without introducing harshness. To complement the redesigned bar, STILLEN engineered new end links specifically tailored to this setup, ensuring correct articulation and long-term reliability.

Finished with a durable protective powder coating, this sway bar is built to withstand road debris, moisture, and corrosion. The result is a suspension upgrade that not only eliminates the factory failure issue but also reduces body roll, improves cornering stability, and enhances driver confidence.

Designed, engineered, tested, and manufactured in-house at STILLEN headquarters in Southern California, this rear sway bar is Made in the U.S.A. and backed by a 1-year manufacturer’s limited warranty against breakage under normal driving conditions.
