QA1 TD507 Stocker Star Double Adjustable Front Shock Absorber

The QA1 TD507 Stocker Star Double Adjustable Shock is an excellent bolt-on solution for improving ride quality and performance on classic GM vehicles. These lightweight shocks feature one-piece forged machined-aluminum bodies that are bright-anodized for durability and great looks, with 5/8-inch hard-chromed centerless-ground piston rods and double-lip wiper seals.

Double Adjustable Performance:

Independent tuning of rebound and compression allows you to fine-tune handling and straight-line performance for any driving condition, with 18 clicks of adjustment on each knob at the base of the shock. The double adjustable knobs provide 324 valving options to dial in the exact ride you want. The shocks rely on deflective-disc valving with 18 levels of damping, which you can select at the twist of a knob—with the shocks in place on the vehicle.
