Energy Suspension universal coil spring isolators are supplied as a two-piece set sized with a 3-3/16" ID, 5-1/4" OD and roughly 3/4" height, offered in red Hyper-Flex material. The market description notes Hyper-Flex lasts several times longer than typical OE isolators, assembles to the chassis like OEM parts, preserves factory ride characteristics and can be used to modestly increase vehicle height without altering ride feel.
