Lee Spring's "SOLID GOLD" online CAD support system is a new FREE service to users of our online catalog. This system allows users to not only view and manipulate images of Lee Spring's 17,000-plus Stock Springs, but also to download 3D or 2D CAD models. SOLID GOLD supports all major 3D and 2D platforms. Non-CAD users will also find this program useful since they can save viewed images as JPEG or TIF Files. Users of Solid Works can use that program's "drag & drop" feature to add the selected part to their existing design. Use one of our user-friendly search engines to make your selection from over 17,000 compression springs, extension springs or torsion springs.
