RideTech Coilover Springs

Built exclusively by Hyperco, RideTech coilover springs work great with RideTech coilover shocks. They're manufactured from high tensile strength chrome silicon steel—the highest grade spring material available. Their high tensile steel wire is lighter and Hyperco's advanced engineering produces springs that achieve the same length and rate with fewer coils and smaller diameter wire than other brands. This allows additional travel before reaching coil-bind. During the manufacturing process, RideTech coilover springs undergo two separate magnaflux inspections to ensure all springs are free from surface imperfections that might lead to early failure. A unique combination of state-of-the-art CNC equipment, along with small town craftsmanship, produces the finest coil springs available anywhere in the world. Key benefits of RideTech coilover springs: * Available in popular lengths, diameters, and spring rates * Many have three fewer coils and smaller diameter wire than competitors * Less weight than standard suspension springs * Additional compression and better travel * More usable deflection * More resistant to bowing than competitors' springs * Designed to fit all standard hardware * Maintain free length and rate throughout a near infinite operational life

Old Man Emu Dakar Leaf Springs

Old Man Emu Dakar leaf springs are offered in numerous spring options to suit a multitude of applications, allowing you to set your vehicle up for recreational or commercial purposes. Feature packed, a set of Emu Dakar leaf springs matched to a set of Old Man Emu shocks will deliver a vastly improved ride, handling and load carrying capability to your vehicle. Emu Dakar leaf springs typically feature: * Draw-tapered and diamond-cut leaves: Ensure the load is progressively distributed over a larger surface area, reducing the high stresses that develop at leaf ends. This provides increased ride quality and protection against leaf breakage, significantly increasing the spring life * Bolt clamps and liners: The leaf clamps are bolted to allow installation of anti-squeak nylon liners * Fully scragged and load-tested: Scragging ensures the spring takes a permanent "set" which reduces the risk of sagging. Load testing ensures the spring meets the required specification. * Graphite coating: To further reduce the friction between the spring leaves and friction pads. * Military wrap: Designed to provide added safety (not available on all applications) * Anti-friction pads: Re-greaseable nylon interleaf liners reduce friction at the leaf tips where the load is the greatest * Flat axle seat area: Allows a positive, safe axle mount reducing spring stress and increasing spring life * Shot peening: The tension side of all leaves is shot peened to reduce spring stress, process can also double the life of a spring * Two-stage leaf pack: Featured on most rear springs for optimum comfort. When unladen, the vehicle is largely riding on the primary stage, with the secondary stage providing additional support when a heavy load is added
