JSPEC2250
Overview:
The JKS Manufacturing JSPEC 2.5" Dual Rate Coil Springs Kit is engineered to enhance your Jeep’s clearance, ride quality, and off-road performance. Designed specifically for Jeep Wrangler JK models from 2007 to 2018 and Jeep Grand Cherokee models from 2005 to 2010, this kit provides a balanced 2.5-inch lift that improves ground clearance without compromising on-road comfort. Whether you’re tackling rugged trails or cruising city streets, these coil springs deliver a smooth, controlled ride with added stability and vehicle control.
Ideal for Jeep enthusiasts who demand versatility, the JSPEC coil springs adapt to varying terrain by offering a dual rate design. This means the springs provide a softer, comfortable ride during everyday driving and firm up progressively as suspension travel increases off-road, maintaining control and confidence in challenging conditions.
Key Features:
Designed to meet the demands of both on-road comfort and off-road capability, the JSPEC coil springs offer several advanced features:
- 2.5-inch lift height for improved ground clearance and aggressive stance
- Dual rate spring design for smooth ride quality on pavement and firmer support off-road
- Complete matched set of front and rear coil springs for balanced suspension performance
- Longer overall spring length to accommodate longer shocks, increasing wheel travel
- Engineered to maintain proper vehicle geometry and handling characteristics
- Compatible with a wide range of Jeep Wrangler JK trims, including Rubicon, Sahara, Sport, Sport S, X, and special editions
- Durable powder-coated finish for corrosion resistance and long-lasting appearance
- Designed and tested for reliability under heavy loads and demanding off-road conditions
Construction & Design:
The JSPEC coil springs are crafted from high-quality steel alloys that provide excellent strength and durability while maintaining the necessary flexibility for dual rate performance. The precision engineering behind the coil geometry ensures consistent spring rates and optimal suspension articulation. Each spring is powder-coated to resist rust and corrosion, extending the lifespan of the components even in harsh environments.
The longer spring length not only facilitates the 2.5-inch lift but also allows the use of longer shocks, which increases wheel travel and improves off-road articulation. This thoughtful design enhances both ride comfort and vehicle control across diverse driving conditions.
Installation & Fitment:
Installation of the JSPEC 2.5" Dual Rate Coil Springs Kit is straightforward for experienced mechanics and Jeep enthusiasts familiar with suspension upgrades. The kit includes matched front and rear springs designed to fit directly onto 2007–2018 Jeep Wrangler JK models and 2005–2010 Jeep Grand Cherokee models without the need for additional modifications. For optimal performance, pairing these springs with compatible shocks is recommended to maximize wheel travel and ride quality.
No cutting or welding is required, and the springs maintain factory ride height geometry, ensuring a level stance and proper alignment. Professional installation is advised to guarantee safety and suspension performance.
