5in Coil Over Kit Bilstein

The 5in Coil Over Kit Bilstein from Kluhsman Racing Products delivers professional-grade suspension tuning for performance boats and watercraft that demand precision handling in variable sea conditions. Designed for builders and enthusiasts who need adjustable ride height and dampening control, this coil-over system replaces factory suspensions with a modular setup that lets you dial in exactly the performance characteristics your vessel requires. Whether you're running tight turns at speed or maintaining stability in rough water, a quality coil-over platform keeps weight distributed and response predictable.

This kit features a 5-inch outside diameter spring paired with a 2-inch Bilstein shock absorber and a 5-inch aluminum sleeve, all finished in black and clear anodized coating for corrosion resistance in saltwater and freshwater environments. The Bilstein damping technology isolates hull vibration and provides consistent feedback across a wide range of throttle inputs and sea states. Aluminum construction keeps unsprung weight minimal—a critical factor in marine applications where every pound affects fuel efficiency and handling response—while the anodized finish ensures durability against spray, salt exposure, and UV degradation.

Serious boaters, racing enthusiasts, and custom builders rely on the 5in Coil Over Kit Bilstein to upgrade aging factory suspension geometry or build purpose-built performance platforms from scratch. Proper installation requires welding or structural reinforcement at mounting points; consult your vessel's frame design and weight distribution before deployment. The compact dimensions (6.4 x 2.7 x 15.4 inches) allow flexible packaging in tight engine bays or under-deck spaces, making this kit suitable for inboards, outboards, and jet-drive platforms where space and weight savings matter most.
