They also feature a three-step sealing system that eliminates seal drag and dirt intrusion. Manufactured in QA1’s Lakeville, Minnesota facility, all QA1 aluminum shocks are 100% dyno tested and serialized and are serviceable and rebuildable by QA1 Authorized Service Centers.

Stocker Star Shocks for Rivieras and Galaxies

QA1 has expanded offerings of its popular Stocker Star shocks to include shocks for 1963-1965 Buick Rivieras and 1960-1964 Ford Galaxies, both of which are available now. Offered in multiple valving options, the smooth body stock mount Stocker Star shocks are direct bolt-on front and rear shocks that offerthe ability to dial in the preferred ride quality with a turn of the knob. With a variety of adjustable valving options available, including double, single, non-adjustable and Drag “R” Series valvings, they can be used in drag racing, street performance, autocross, road racing and street applications. The variety of valving options available allows drivers to choose the right level of adjustability based on their driving style and needs, whether they want standard consistent valving or the ability to really fine-tune their compression and rebound based on street or strip.

All systems include two billet aluminum shocks, high travel springs, mounting brackets and all mounting hardware.
