Description
When a race car is “tight” in the center or “loose” on exit, you often don’t have the luxury of unbolting the suspension to swap springs between heats. The Longacre 61070 Coil-Over Spring Rubber is the industry-standard tool for making lightning-fast chassis adjustments.
By inserting this high-density Black (Firm) rubber into the coils of your spring, you effectively “lock out” a portion of the active wire, instantly increasing the spring rate. This allows a crew chief to add “wedge” or stiffen a specific corner of the car in seconds. Whether you are running a Dirt Late Model, Modified, or Asphalt Stock Car, these rubbers are the most cost-effective way to find the “handle” on a changing track surface.
Key Features
-
Instant Spring Rate Tuning: Increases the effective rate of your coil spring without the need for tools or suspension disassembly. Perfect for “tuning-on-the-fly” during practice sessions.
-
High-Density Orange Compound: The Orange durometer is engineered for a firm, consistent response, providing a significant rate increase compared to softer yellow or black rubbers.
-
Standard 1″ Spacing Design: Specifically sized to fit standard racing coil springs with 1-inch spacing between active coils, ensuring a snug fit that stays put under heavy compression.
-
Performance Stability: Manufactured from a specialized rubber compound that resists “crushing” or permanent deformation, ensuring repeatable handling changes lap after lap.
-
Tool-Free Installation: Can be slid into the spring with the car simply jacked up, making it the fastest handling adjustment available in the pit box.
