QR-04 without Electrical Data Connector

The QR‑04 series collection contains steering wheel quick release coupling halves without electrical data connectors, offered in large‑diameter male and female halves including 19.05 mm internal diameter variants. Components are machined coupling halves for motorsport and professional automotive steering quick release systems, intended for use where a mechanical disconnect is required without integrated data or power contacts. Items cover standard big‑size steering wheel couplers and replacement halves for workshop and trade applications.

Select couplers by matching shaft diameter, bore (19.05 mm where specified), locking interface and thread form; confirm mechanical fit with the steering column and wheel boss before installation. Installation and service should follow the equipment manufacturer's instructions, use correct torque and retaining hardware, and include regular inspection for wear and alignment in track, workshop and industrial automotive environments.
