Integra Racing 421 Series Steel Twin Tube Shocks are designed and manufactured for both coil-over and non coil-over racing applications. 421 series shocks have an ideal design for those who like to mount shocks upside down to reduce unsprung weight! An innovative cam over seal design eliminates over 60 percent of normal seal drag, allowing each shock to have the least amount of drag compared to comparable steel production shocks on the market today! 421 series steel body shocks feature a 5/8 in. diameter shaft and a 2.10 in. outer diameter body, as well as are available in many different valving combinations to meet your specific track/car needs.
