5in Coil-Over Kit

The 5in Coil-Over Kit from AFCO Racing Products represents a critical suspension upgrade for high-performance marine and boating applications where ride quality and handling precision matter on the water. Built for operators who demand responsive, predictable hull dynamics—whether you're running offshore or navigating rough inland conditions—this coil-over assembly delivers the kind of suspension control that transforms how your boat behaves under load and in varying sea states. If you're pushing your vessel hard and want to eliminate excessive pitching, porpoising, or unpredictable trim response, this is the system engineered to solve those problems.

A 5-inch coil-over design uses a helical spring wound around a damper shaft, allowing independent adjustment of spring rate and damping characteristics to fine-tune your vessel's suspension geometry. This configuration reduces unsprung weight while maintaining consistent load support across acceleration, cornering, and deceleration cycles. The compact footprint—measuring 8 x 3 x 13.5 inches and weighing just 2.9 lbs—makes installation feasible on platforms with spatial constraints, while AFCO Racing Products' proven manufacturing standards ensure the spring maintains its rate over thousands of compression cycles without sagging or degradation.

Serious boaters, performance enthusiasts, and operators running modified platforms benefit most from this suspension system, particularly those who've experienced excessive bow-rise on acceleration or instability at cruise. Installation requires proper spring perch alignment and damper mounting—consult your vessel's suspension specification sheet to confirm compatibility with your existing mount points and weight distribution. Experienced technicians and race-prepped boats are the primary audience; this is not a bolt-and-forget component, but rather a precision tuning element that rewards proper setup with dramatically improved handling and crew comfort in challenging conditions.
