Product Description

The QA1 GS401 Single Adjustable Front Pro-Coil Shock is designed for GM vehicles converting to front coil-over suspension. This shock features a single adjustment dial for easy tuning of ride quality and handling characteristics, along with a threaded body that allows approximately 0" to -2" ride-height adjustment.

The shock is compatible with OE stamped or tubular control arms and is built with a high-travel aluminium body for reduced unsprung weight. Being fully serviceable and rebuildable, the GS401 is ideal for street rods, restomod projects, and classic GM builds that require a premium coil-over style front shock without including springs.

Since springs are not included, users must select appropriate coil springs based on vehicle weight and ride preference. This product is intended for front coil-spring conversion setups, and compatibility with your specific vehicle geometry should be verified prior to installation.
