Cusco Sway Bar Riser R CKV36 NJ50 25 mm

Cusco Sway Bars (also known as Stabilizer Bars) are one of the most effective and affordable suspension upgrades for improving handling precision, reducing body roll, and fine-tuning chassis balance. Designed and manufactured in Japan, each Cusco sway bar is engineered to OE or motorsport-grade tolerances, offering a substantial performance increase without compromising reliability or comfort.

These sway bars work by connecting the left and right suspension arms together, resisting independent movement and keeping the car flatter during hard cornering. The result is sharper turn-in, more predictable mid-corner behavior, and faster weight transitions – giving you the confidence to push the car harder through corners.

Cusco’s bars are cold-formed from high-strength spring steel and finished in their signature Cusco blue powder coating. Depending on the application, bars may be solid or hollow (tubular) to provide the optimal strength-to-weight ratio for your specific vehicle. Adjustable variants include multiple endlink mounting points, allowing you to tailor the bar’s stiffness to your driving style – whether that’s aggressive canyon carving, competitive autocross, or a compliant street ride.

Compared to soft factory sway bars (or none at all, in some cases), Cusco sway bars can significantly reduce understeer or oversteer depending on front or rear fitment. When combined with proper alignment and quality tires, they can transform the feel of the car, delivering an immediate increase in chassis feedback and lateral grip.
