Sway Bar Arm 1.50 x 48 Spl 30 Deg

The ALLSTAR PERFORMANCE Sway Bar Arm 1.50 x 48 Spline 30 Degree is a precision-engineered suspension component built for circle track racing and performance vehicles that demand consistent handling characteristics. This sway bar arm serves as a critical link between the suspension geometry and the anti-roll bar, translating driver input into predictable weight transfer and chassis balance across varying track conditions.

Constructed from solid steel in a natural finish, the component measures 1.50 inches in diameter with a 48-spline connection and 3/4-inch thickness, engineered to withstand high-load racing environments. The 30-degree angle geometry is designed to optimize suspension kinematics for oval-track applications, where precise control of body roll and consistent cornering stability directly impact lap times and tire wear patterns. The 48-spline interface ensures repeatable connection strength and alignment critical to suspension tuning repeatability.

Competitors and circle track teams use sway bar arms like this to fine-tune suspension response without full geometry changes. The ALLSTAR PERFORMANCE design maintains dimensional consistency across production runs, allowing teams to standardize their suspension packages and isolate variables during setup development. Whether building a new race car or refreshing suspension components on an existing platform, this sway bar arm delivers the precision fit and durability required for sustained racing operation.

ALLSTAR PERFORMANCE remains a recognized manufacturer of suspension components and chassis hardware for circle track racing, with products widely adopted across short-track and regional competition. Weighing 5.55 lbs, this component is a direct replacement or upgrade part for vehicles running similar suspension architecture and spline specifications.
