The Hyperco 2.5-3.5-300TENDER is a precision-manufactured tender spring designed for high-performance racing and suspension tuning applications. This helper spring features a 2.5-inch inner diameter and 3.5-inch overall height with a 300 lb/in spring rate.

Key Features:

• 2.5-inch inner diameter for compatibility with standard coilover systems
• 3.5-inch tall compressed height
• 300 lb/in spring rate for optimal load support
• Precision wound from high-quality spring steel
• Consistent rate throughout compression range
• Designed to work in conjunction with main springs to prevent coil bind

Tender springs (also called helper springs) are essential components in racing suspension systems that maintain preload on the main spring, preventing separation and ensuring consistent damper performance. The compact 3.5-inch height makes this tender spring ideal for space-limited coilover installations while the 300 lb/in rate provides adequate support without significantly affecting overall suspension characteristics.
