King Shocks SPR3-14-700 3.0" ID 14"700 lb/in Coilover Spring Blue for 2.5"Shocks

Vehicle Fitment

• Universal - fits all coilover shock absorbers with a 2.5" outside diameter body and a 3.0" spring perch seat. Compatible with King Shocks 2.5" coilovers and all other brands of 2.5" OD coilover shocks accepting a 3.0" ID spring.
• Verify the spring seat diameter and required free length on your specific shock before ordering. This spring has a 3.0" inside diameter, 14" free length, and 700 lb/in rate.

Fitment Notes

• The SPR3-14-700 is a 3.0" ID coilover spring designed for use on 2.5" outside diameter shock bodies. It is not compatible with 2.0" body shocks (which use the 2.5" ID SPR25 series) or 3.0" body shocks (which use the 3.75" ID SPR375 series). Confirm your shock body diameter before ordering.
• At 14" free length and 700 lb/in, this is a very heavy-rate primary spring suited for the heaviest off-road vehicles, maximally loaded trucks, and competition builds on 2.5" body shocks where extreme suspension loads demand the firmest available rate to maintain ride height and prevent bottoming under load. It is not appropriate for lightweight applications, moderate-duty vehicles, or use as a tender spring.
• Spring selection requires matching free length, rate, and ID to the shock travel and the vehicle's suspension geometry, weight, and intended use. A 700 lb/in rate is a significant commitment - consult your suspension builder or King Shocks directly to confirm this rate is correct for your specific application before ordering.
• Sold individually - one spring per order. Most coilover applications require two or more springs per build; order the quantity needed.
• The spring rate of 700 lb/in is etched directly into the top coil for clear identification after installation and hard use.

Features

• 700 lb/in linear spring rate - King's heaviest 14" SPR3 primary spring rate, delivering maximum body motion control under the extreme suspension loads generated by heavy vehicles, fully loaded trucks, and high-speed competition applications on 2.5" body shocks; the 700 lb/in rate is appropriate where vehicle weight, payload capacity, or aggressive sustained driving produces forces that a 600 lb/in or lighter spring cannot adequately resist without bottoming or excessive ride height loss
• 14" free length - a mid-length primary spring dimension compatible with the spring perch geometry of standard 2.5" body coilover builds, providing adequate working travel for single-rate primary configurations in this high-rate range
• Wound specifically for off-road applications from the ground up - not repackaged automotive or industrial springs. King designs spring rate, wire diameter, and coil geometry exclusively for off-road suspension use, with every specification validated through real-world competition testing from Baja to Dakar
• High-tensile chrome silicon wire - the highest grade spring wire material, providing the tensile strength and fatigue resistance required to sustain a consistent 700 lb/in rate under repeated heavy-load cycles without sag, set, or rate degradation over the life of the spring
• Closed and ground ends - both ends are precision ground flat for square, stable seating on spring perches without rocking, cocking, or producing lateral side loads on the shock shaft; at high spring rates, correct end geometry is especially critical as off-axis loads are amplified and can accelerate shock seal and bushing wear if the spring is not seated correctly
• Blue powdercoat finish - provides corrosion resistance and visual identification within King's color-coded spring lineup; durable against rock chips, trail debris, mud, and UV exposure in off-road environments
• Spring rate etched on top coil - permanently etched into the metal before powdercoat application, remaining legible after installation and extended field use for rate confirmation without spring removal
• Compatible with King Shocks and all other brands of 2.5" OD coilover shocks - the SPR3 series is a universal spring line, not exclusive to King shock bodies
• Made in USA - manufactured to King Shocks' specifications using domestic production processes and materials
• Lifetime warranty against sagging and breakage - King covers these springs for life to the original purchaser; in the rare event of failure, replacement is provided with no questions asked

Product Description

The King Shocks SPR3-14-700 is a 3.0" inside diameter, 14" free length, 700 lb/in linear coilover spring for use on 2.5" outside diameter shock bodies. It is a universal spring compatible with King Shocks 2.5" coilovers and all other brands of 2.5" OD coilover shocks that accept a 3.0" ID spring. Sold individually. Made in USA. Lifetime warranty against sagging and breakage.

At 700 lb/in, this is the heaviest rate in the 14" SPR3 lineup and is intended for applications where nothing lighter will do - heavy performance trucks at or near payload capacity, competition vehicles generating sustained high-G lateral and braking loads, and high-speed desert racing builds where vehicle weight combined with aggressive driving produces suspension forces that exceed the capacity of lighter spring rates. On 2.5" body shocks, the 700 lb/in rate maintains ride height under extreme load, resists bottoming through the full travel range, and keeps the suspension geometry consistent under the conditions that would compress a lighter spring to or near its bind point.

Like all King coilover springs, the SPR3-14-700 is wound from high-tensile chrome silicon wire developed exclusively for off-road use. At 700 lb/in, wire quality and manufacturing precision are critical - the higher the rate, the more the spring wire is stressed per inch of deflection, and the more important consistent wire properties become for maintaining the rated spring rate across the full travel range without progressive sag. King's chrome silicon wire and USA production standards deliver the rate accuracy and long-term durability that demanding off-road applications require. Closed and ground ends ensure flat, square seating, and the rate is permanently etched into the top coil for field identification.
