Hyperco 18Z1000-12 Conventional Front Coil Spring 5.5" OD 12" Length 1000 lb/in Rate

The Hyperco 18Z1000-12 is a conventional suspension spring with a 5.5 inch outer diameter, 12 inch free length, and a spring rate of 1000 lb/in. Designed for high-performance motorsports applications, this conventional spring is primarily used in circle track racing where outer diameter size and free length requirements are often determined by sanctioning body rules.

Key Features:

• Features Hyperco's Dynamic Travel Response (DTR) enhancement technology for improved performance requirements for travel and rate linearity
• One end of the spring is open, the other end is closed and ground
• Durable black powdercoated finish
• Manufactured from the highest quality chrome silicone steel
• Allows for 4.5 inches of travel
• Sold individually

The material used in producing Hypercoils undergoes two separate magnaflux inspections—once before manufacture and again after coiling—to ensure the wire is free from surface imperfections. The Dynamic Travel Response design allows the spring to exceed performance requirements for travel and rate linearity while being designed with significantly less physical weight, giving racers a competitive edge on both dirt and pavement tracks.
