Hyperco 2.5-3.5-025TENDER Tender Spring 2.5" ID x 3.5" Tall

The Hyperco 2.5-3.5-025TENDER is a precision-engineered tender spring designed for advanced suspension tuning applications. This helper spring features a 2.5-inch inside diameter and stands 3.5 inches tall in its uncompressed state.

Key Features:

• 2.5-inch inside diameter for compatibility with standard coilover systems
• 3.5-inch free height provides optimal preload characteristics
• Manufactured from high-quality spring steel for consistent performance
• Precision wound for uniform rate and durability
• Designed to work in conjunction with main springs to improve suspension response

Tender springs, also known as helper springs, are used to maintain constant contact between the main spring and spring perch during low-load conditions. This eliminates suspension noise and improves damper control by preventing the main spring from becoming unloaded during rebound. The compact 3.5-inch height makes this tender spring suitable for applications where space is limited, while the 2.5-inch ID allows it to fit over standard coilover shafts or inside appropriately sized main springs.
