Tender springs, also known as Helper springs, are fitted to a coil over to either correct the spring travel (helper) or create a progressive spring rate (tender). Tender springs are very common on front BMW coil overs to correct the ride height and account for the shorter front springs.

As a Helper spring, the spring becomes fully compressed into a solid block at the normal ride height and is only there to take up space. This is to optimize the travel of the main spring and shock damper and also used during setup and corner balancing to achieve the desired ride height. They also keep the main spring from becoming loose during shock extension, such as when lifting a wheel.

In a Tender spring scenario, the spring rate is stiffer than a Helper spring and the spring does not become fully compressed until cornering at high speeds or rapid weight transfers. This becomes a soft intermediary spring that absorbs small bumps and works during low speed cornering, which is the benefit of progressive springs. It will become compressed during hard cornering or weight transfers and the stiffer main spring will take over. Many street coil overs will use a soft tender spring to give a more comfortable ride.

Eibach ERL tender springs are made with high grade tensile steel for superior strength and weight savings - critical considerations for race use. Their spring designs achieve maximum travel with the smallest block heights and their spring rate consistency is what keeps suspension engineers insisting on Eibach springs. Springs are manufactured either in Germany or California and each spring is individually tested and block set. They are available in several lengths and rates using the imperial system (inches and pounds). Metric rates and conversions are also available, please inquire.

Install note: a spring joiner is required between the Tender and Main springs (sold separately).
