Sway Bar 1.25in x 37.5 1.50-48 Spline

The Sway Bar 1.25in x 37.5 1.50-48 Spline by MPD Racing is an essential suspension component for performance-oriented vehicle builds and track-focused modifications. Sway bars (also called anti-roll bars) reduce body roll during cornering by distributing weight transfer more evenly across the suspension geometry, resulting in sharper handling and improved vehicle dynamics.

This 37.5-inch bar is designed for applications requiring a 1.25-inch diameter shaft with 1.50-48 spline engagement, making it ideal for racers and enthusiasts who demand precision-engineered suspension upgrades. Constructed as a solid-diameter sway bar, this component features a 1.25-inch diameter shaft that provides optimal rigidity-to-weight balance for high-performance applications without excess rotational inertia.

The engineering focus on spline design prevents slippage during aggressive cornering events, a critical factor for consistent lap times and predictable vehicle behavior in competitive environments. At 10.5 pounds, the bar's weight is kept minimal for motorsports use, while its length accommodates mid-size to full-size vehicle platforms, making it a versatile choice for track-day drivers.
