Red die spring. There are three brands sold by industrial supplier MSC industrial supply. It’s hard to tell from the photos what size it is because the hole was not measured properly. My guess is in the link below, but with proper measurement you should be able to identify the spring from the MSC site. From the looks, these may have been used since the overall length is about 7.5”. Springs in this size come in one inch increments, so these were 8” springs that have probably been over compressed. MSC uses generic photos so go by the dimensions, not their square wire photo.
