The Hyperco 18Z1200 is a 9.5 inch long, 5.5 inch outer diameter conventional suspension spring with a rate of 1200 pounds per inch that allows for 2.917 inches of travel. Engineered to deliver superior suspension performance in motorsports, this spring features reduced physical weight and provides exceptional travel and rate linearity.

Key Features:

• Both ends closed and ground flat for consistent performance
• High travel conventional front spring brings closed end NASCAR style spring technology to the conventional spring line
• Black powder coated finish for durability and corrosion resistance
• Constructed from high-quality steel for reliable motorsports applications
• Built to meet or exceed the strict requirements of motorsports sanctioning bodies

The closed end design directly impacts the number of active coils that deflect during spring compression, creating a very progressive spring rate through the initial stages of deflection.
