QA1 TN601 Stocker Star Non-Adjustable Shock Absorber 11.50-17.00 Stud/Stud Twin-Tube Aluminum

The QA1 TN601 Stocker Star Non-Adjustable Shock Absorber delivers premium aluminum performance at a budget-friendly price point. Sharing the same core components as the rest of QA1's best-selling Stocker Star lineup, this non-adjustable twin-tube shock bolts directly into factory mounting locations—no cutting, welding, or suspension modification required. It's an ideal upgrade over worn or outdated OEM steel shocks for classic muscle cars and trucks.

Constructed from lightweight billet aluminum with a smooth body design, the TN601 features a 5/8 in. hard-chromed, centerless-ground piston rod and double-lip wiper seals for long-term durability and consistent damping. With a compressed length of 11.50 in. and an extended length of 17.00 in., this shock uses stud mounts on both ends for a secure, direct-fit installation. Black polyurethane bushings are included.

Installation Notes: Stud mount lengths are measured to the shoulder of the stud; add 13/16 in. per stud mount for installed compressed length. Some front applications may require the lower A-arm to be dropped for installation. The body diameter may be too large for bottom-mount installations on some applications, and certain control arm shock openings may need to be enlarged to accept a QA1 shock. Lengths may vary slightly. Due to variations from factory ride height, verify actual ride height for your specific application prior to installation.
