This collection contains DJR Team Penske Racing socket retaining rings designed for professional motorsport and automotive workshops. Stock includes 1" drive retaining rings, such as the RET-RING 1"DR (2-5/8" ID), sized to secure sockets and extensions on square‑drive tools used in pit, workshop and industrial environments. Products are specified by drive size and inner diameter to match common socket profiles.
Select by matching the ring to the tool's drive size and the socket's internal diameter; confirm compatibility with 1" square drives where applicable. Install using the correct retaining hardware and follow the tool manufacturer's instructions. For pneumatic and high‑vibration applications inspect regularly for wear, deformation or loss of spring tension and replace if any damage is evident to maintain secure retention during use.
