Helper Spring 2.43in Dia 2.95in Tall

The Helper Spring 2.43in Dia 2.95in Tall by EIBACH is a precision auxiliary suspension component engineered to support factory springs under load, preventing sagging and improving ride height consistency. Built for truck owners, fleet operators, and enthusiasts who regularly haul cargo, tow trailers, or carry heavy payloads, this helper spring reduces the strain on primary springs and extends their service life. Whether you're managing seasonal weight fluctuations or running a work truck that demands reliability, EIBACH's design delivers the support your suspension needs.

Measuring 2.43 inches in diameter with a 2.95-inch working height, this helper spring is engineered to nest alongside or work in tandem with OEM coil springs, providing supplemental load support without altering ride quality under normal driving conditions. EIBACH's manufacturing standards ensure consistent spring rates and durability across thermal cycles and repeated compression cycles. The compact footprint allows seamless integration into tight spring pocket geometries, and the spring's progressive characteristics activate only when needed, ensuring your unloaded ride remains compliant and comfortable while delivering confidence when weight is present.

This helper spring is ideal for pickup truck owners, commercial vehicle operators, and suspension builders seeking a straightforward solution to load sag without a full air suspension overhaul. Installation typically requires access to the spring perch area and pairs well with existing coil spring configurations on domestically-manufactured light-duty and mid-size trucks. Always verify fitment against your specific vehicle's suspension architecture and existing spring specifications before ordering, as helper spring selection depends on primary spring rate and available mounting space.
