Conv Front Spring 5in x 9.5in x 500#

The Conv Front Spring 5in x 9.5in x 500# from AFCO Racing Products is a high-performance coil spring engineered for serious boaters and marine suspension tuning. Whether you're running a performance boat with adjustable suspension, towing heavy loads, or upgrading to a custom marine chassis, this conventional front spring delivers the precise load support and handling characteristics needed for demanding water conditions. Built to withstand salt spray, vibration, and dynamic stress, it's an essential component for anyone investing in professional-grade suspension performance.

This spring features a 500 lb/in rate with a 5-inch outer diameter and 9.5-inch compressed length, delivering responsive front-end support and consistent ride geometry across rough water and variable loads. The black powder coat finish resists corrosion in marine environments, protecting against salt intrusion and UV damage. As a conventional coil design, it works in tandem with dampers and control arms to maintain precise suspension geometry, absorbing shock loads while maintaining predictable control feel—critical for maintaining speed and confidence in offshore conditions.

This front spring is ideal for boaters upgrading custom chassis-based watercraft or performance suspension systems where OEM springs fall short. Weighing 6.55 lbs per unit, installation requires coordination with existing dampers and control arm geometry to ensure proper ride height and suspension travel. Verify compatibility with your suspension frame, mounting points, and complementary spring rates to avoid binding or over-compression. Professional installation is recommended to ensure correct preload and alignment settings for optimal handling and durability.
