Energy Suspension rear bump stops for 1996–2009 Toyota 4Runner are red Hyper-Flex polyurethane snubbers designed to cushion a collapsing suspension and help prevent bottoming-out. These rear bump stops are sized for the 4Runner rear application, aim to reduce damage to shocks and struts, and are described as longer-lasting Hyper-Flex polyurethane replacements compared with original rubber units.
