Hypercoil Coilover Dual Rate Springs


 Hypercoil Coilover Dual Rate Springs UHT (Ultra High Travel) Springs are designed specifically for light rate and high travel coil-over applications. UHT design features a large "body bulge" over the standard design to allow for additional deflection, rate linearity and restistance to bowing.


HYP 14B0200/425UHT is a 14” free length spring with 2.5” end ID’s and a dual rate of 200lb/in transitioning to a secondary rate of 425lb/in. The rate transition started at 625lb of spring load and was complete by 800-825lb of spring load.

Initially intended for the left rear of pavement late-models running on medium banked tracks, the 14B0200/425UHT quickly found favor on the right front (as well as other locations) of Dirt Late-Models running in series where spring stacking was outlawed.

This spring features an extremely linear 200lb/in rate through the first 3.125” of deflection (approximately 625lb of spring load) at which time the rate transitions to the rate through a transition range of 0.750”- 1.00”.

Rate transition is completed by the time the spring load rises to 800-825lb, and is fairly linear until coil bind. The light rate section of the spring is characterized by closely wound coils and the higher rate by wider spaced coils. The wide coil spacing provides excellent opportunity for tuning the second rate with spring rubbers.
