Spring 2.25in ID Tender Linear

The Eibach Spring 2.25in ID Tender Linear coil spring is a precision suspension component designed for builders and mechanics seeking fine-tuned load management in custom suspension builds. This tender spring excels in applications where lighter spring rates are required to complement primary springs or serve as a helper spring in multi-spring setups, making it essential for low-offset applications, air suspension systems, or progressive spring configurations. Whether you're fine-tuning ride height, reducing coil bind risk, or optimizing suspension geometry in street rods and custom vehicles, this linear-rate spring delivers consistent, predictable performance.

Engineered by Eibach, a leader in suspension innovation, this spring features a 2.25-inch inner diameter with a 150 lb/in spring rate and 2.72-inch working length, making it compatible with standard shock absorber and suspension eyelet configurations. The steel construction is protected by a durable black powder coat finish, resisting corrosion and road salt while maintaining structural integrity under repeated compression cycles. The linear rate characteristic ensures progressive load response without rate spike, providing stable handling characteristics across the full suspension travel range—critical for vehicles running custom geometry or extreme ride heights where non-linear rates would introduce unpredictable behavior.

Mechanics and suspension builders favor this Eibach tender spring when constructing dual-rate systems, air suspension helpers, or when matching companion springs in multi-link or independent suspension architectures. At 2 lbs per unit and compact 4.125 x 4.125 x 6-inch dimensions, installation integrates seamlessly into tight engine bays and suspension mounting points. This spring is sold individually, allowing you to purchase the exact quantity needed for your specific suspension package, whether upgrading a single corner or building a complete custom setup.
