Product Description

The Eibach 9310.14 Drag-Launch Coil Spring Kit is a performance-oriented suspension upgrade engineered for Ford Mustang models from roughly 1979 through 2004. Designed specifically for drag racing and straight-line performance, this kit focuses on enhancing traction at launch by improving weight transfer to the rear wheels. Unlike typical street lowering springs, the Drag-Launch springs are tuned to help control wheel hop and maximize grip off the line, which can lower quarter-mile times and improve consistency under hard acceleration.

Constructed from high-tensile spring steel with a durable gray powder-coated finish, this kit is built to withstand the rigors of high-performance driving. Depending on vehicle weight and setup, ride height may sit moderately lower than stock when the car is at full weight, but the primary objective is optimized traction and weight transfer during aggressive launches rather than traditional stance lowering. The 9310.14 springs are ideal for Mustang owners who focus on drag strip performance and want a suspension setup engineered for improved launches and straight-line stability.
