3in Dual Rate Long Travel Coil Springs Pair

The 3in Dual Rate Long Travel Coil Springs Pair from SKYJACKER delivers the suspension geometry your lifted truck needs when tackling serious off-road terrain or hauling heavy payloads. Purpose-built for vehicles that demand both ride comfort on pavement and articulation in the backcountry, this coil spring pair addresses the core limitation of stock suspensions: inadequate travel and inconsistent spring rate under varying loads. Whether you're upgrading a full-size truck for overlanding, towing, or rock crawling, dual-rate springs allow progressive support that keeps your rig stable at highway speeds while compressing smoothly over obstacles.

Dual-rate technology uses two coil sections with different spring constants, so initial compression feels soft and compliant—ideal for absorbing small bumps—while deeper travel engages a stiffer rate that prevents bottoming and protects frame and drivetrain during extreme articulation. The 3-inch lift height pairs with long-travel geometry to expand suspension travel considerably beyond OEM specs, crucial when you've added aftermarket wheels, tires, and accessories that increase unsprung weight. Each spring in this pair weighs approximately 18.9 lbs and measures 12.35 x 7.05 x 22.75 inches, engineered to handle the spring rates and cycle life demands of modern performance trucks. SKYJACKER's reputation in the suspension industry reflects decades of testing and real-world feedback from serious enthusiasts and professionals.

This spring pair benefits truck owners who've already installed or plan to install a coordinated suspension package, including shocks, sway bars, and control arms tuned to the same ride height and travel spec. Installation requires removal of original coil springs and transfer to a compatible strut or spring bucket—a task best performed by a qualified mechanic or suspension specialist with proper lift equipment and torque specifications. Verify fitment with your truck's year, make, and model before purchase, as suspension geometry varies significantly across platforms. These springs work in tandem with quality dampers (shocks) and proper wheel alignment to achieve their design intent; skipping any component in the system undermines performance and safety.
