Hyperco 18Z0800-11 Conventional Front Coil Spring 5.5" OD 11" Length 800 lb/in

The Hyperco 18Z0800-11 is a high-performance conventional style front suspension spring designed for circle track racing and motorsport applications. This precision-engineered coil spring features a 5.5-inch outer diameter with an 11-inch free length and delivers a spring rate of 800 pounds per inch, providing 4.375 inches of travel for optimal suspension performance.

Key Features:

• 5.5-inch outer diameter with 11-inch free length
• 800 lb/in spring rate for consistent performance
• One end open, one end closed and ground design
• Constructed from high-tensile chrome silicon steel
• Powder coat finish (currently produced in silver, older stock may be dark blue)
• Lightweight design compared to standard suspension springs
• Dynamic Travel Response technology for optimized vehicle performance
• 4.375 inches of available travel

Hyperco's conventional front springs are engineered with their proprietary Dynamic Travel Response design, which maximizes travel and rate linearity while minimizing physical weight. The closed-end design directly impacts the number of active coils during compression, creating a progressive spring rate through initial deflection stages and enabling more aggressive race setups with increased dynamic travel on the track.
