DUAL RATE HELPER SPRING, 1.9'' ID, 2.4'' Long - 300 POUND

"

Want to fine tune your suspension characteristics? No problem. Speedwerx has chrome silicone helper springs available in many different rates.

Be sure to use the formula provided to get the settings you desire.

Dual Rate Spring Kit Formula:
(Short Spring X Long Spring) ÷ (Short Spring + Long Spring) = Initial Rate
Long Spring = Finish Rate

    SAMPLE:
    (300 X 140) ÷ (300 + 140) = 95 Initial Rate
    Long Spring = 140 Finish Rate
    95/140 Spring Rate

You can also use the aluminum transition spacer to fine tune the transition point on the dual rate set-up. No aluminum spacer would use the 95 Lb. rate longer , and the 1” aluminum transition spacer would shorten the 95 lb rate duration by transitioning to the stiffer rate sooner.

We also have a variety of spring spacers and aluminum transition spacers to work together with our helper springs.
