Longacre Racing Products Coil Over Spring Rubber

Longacre Racing Products coil-over spring rubbers, also called coil spring rubber inserts or spring rubbers, let you fine-tune the spring rate on a circle track car. Each rubber fits between the coils of a coil-over spring. This lets you change the spring rate without replacing the spring.

Key Features:

• Adjust spring rate to dial in chassis setup
• Quick to change during practice sessions or pit stops
• Offered in several durometer (hardness) ratings, from soft to hard
• Color-coded so the rubber rating is easy to identify
• Available in standard, large spacing and deep groove styles for different coil spacing and spring setups
• Used by virtually all Sprint Cup teams in every race, according to Longacre
• Made in the USA

The large spacing and deep groove styles fill the bigger gaps between coils on newer coil-over springs. These springs have fewer coils, which gives more travel before coil bind. Longacre has supplied racers for decades, from individual racers to top professional teams.

For racing use only.
