Conventional Spring 13in x 5in x 225#

The Conventional Spring 13in x 5in x 225# is a high-performance suspension component designed for professional racers and automotive enthusiasts seeking consistent handling characteristics. These Bulletproof series springs are engineered to maintain their rate and height over time, providing a reliable foundation for heavy-duty racing applications. By offering a predictable 225 lb/in spring rate, this component allows drivers to fine-tune their vehicle's weight transfer and cornering stability during high-stress maneuvers.

Constructed from high-tensile steel, the Conventional Spring 13in x 5in x 225# features a 5-inch outer diameter and a 13-inch free length to fit standard conventional suspension setups. The specialized copper powder coat finish provides superior corrosion resistance while protecting the integrity of the steel through thousands of compression cycles. This design utilizes advanced metallurgy to minimize spring fatigue, ensuring that the coil does not lose its original height even under extreme racing conditions.

Drivers looking for a specific balance between compliance and support will find this 225-pound spring rate ideal for various track surfaces and vehicle weights. The precision manufacturing of the Conventional Spring 13in x 5in x 225# ensures that the spring rate remains linear throughout its travel, which is critical for predictable suspension tuning. This coil is sold individually and is compatible with standard 5-inch outer diameter spring perches common in many domestic and custom racing chassis.
