EIBACH MAIN AND HELPER SYSTEM A Helper spring is used to prevent the Main spring from becoming loose in the spring seat when the suspension is unloaded or at full droop. The Helper spring, unlike the Tender spring, has very little spring rate, and therefore has no effect on the suspension characteristics of the vehicle. Up to 2 (50mm) of spring-to-perch gap can be covered with the use of a Helper spring. -Ultra-Lightweight for Reduced Unsprung Mass -Maximum Deflection in Combination with -Smallest Block Heights -Exceptional Block Resistance and Durability -Precision Tolerances,Tightest in the Industry -Lowest Side Loads with Load Center Ideally -Highest Linearity and Guaranteed Rate -Consistency Within 2% Of Advertised Rate -Each Spring Individually Tested and Rated -Eibach Springs Lifetime Warranty
