Hypercoils 12" UHT Barrel 2-1/2" I.D. Coil-Over Spring - 300 lb. Analog Speedometer Dyno tests showed gains averagingUltra High Travel (UHT) Hypercoils are designed specifically for light rate high travel coil over applications (dirt & pavement). UHT designs meet the requirements of soft spring big bar set ups and remain consistent in free length & installed height. The new UHT design features a larger "body bulge" over our standard OBD designs, allowing for additional deflection, rate linearity and resistance to bowing. Currently available in 12", 14", 15" & 16"
