Construction & Design

H&R Sport Springs are manufactured using premium Bekaert wire sourced from Belgium, renowned for its exceptional tensile strength and resilience. Each spring undergoes a meticulous cold winding process followed by heat tempering to enhance elasticity and fatigue resistance. The shot-peening treatment further relieves internal stresses, ensuring long-lasting performance under demanding conditions.

To protect against corrosion and wear, the springs receive a phosphate treatment before being finished with a durable powder coat. This multi-step manufacturing process results in springs that maintain their performance characteristics and appearance over time, even in harsh environments.

Engineered in Germany to meet TUV certification standards, these springs guarantee consistent quality, precise fitment, and reliable performance for your Jeep Grand Cherokee or Commander.

Installation & Fitment

H&R Sport Springs are designed as a direct fit replacement for the factory coil springs on 2005–2010 Jeep Grand Cherokee (excluding SRT8) and 2006–2010 Jeep Commander models with the 5.7L HEMI engine. Installation requires standard suspension disassembly and reassembly procedures, typically performed by a professional technician or experienced enthusiast.

No additional modifications are necessary, and the springs work best when paired with compatible sport shock absorbers to maintain optimal ride quality and handling balance. Proper alignment after installation is recommended to ensure safe and precise vehicle dynamics.
