Speedmaster DANA 30 27 Spline TorqueWorm Helical Gear Limited Slip Differential LSD 3.73 Ratio

The Speedmaster DANA 30 Limited Slip Differential is a high-performance helical gear LSD designed for Dana 30 axles with 27 splines and a 3.73 gear ratio. This TorqueWorm differential upgrade improves traction and handling by distributing power more effectively between wheels during acceleration and cornering, making it ideal for performance driving, off-road applications, and vehicles requiring enhanced differential performance.

The helical gear design and limited slip technology work together to minimize wheel slip while maintaining smooth operation under normal driving conditions. This differential is a direct replacement for stock Dana 30 assemblies, offering drivers a proven upgrade path for increased driveline control and responsiveness. The 3.73 ratio is tuned for vehicles seeking enhanced acceleration and performance characteristics.
