Construction & Design

H&R Sport Springs are manufactured using high-grade Bekaert wire sourced from Belgium, known for its superior tensile strength and resilience. Each spring undergoes a meticulous manufacturing process including cold winding to maintain precise coil geometry, heat tempering to enhance material strength, and shot peening to improve fatigue life. Following these treatments, the springs are phosphate-treated and powder-coated to provide a durable, corrosion-resistant finish that withstands harsh road conditions and environmental exposure.

The progressive-rate design ensures the springs deliver a comfortable ride during normal driving while progressively stiffening under heavier loads or aggressive cornering. This engineering approach balances sporty performance with everyday usability, making these springs an excellent upgrade for Jeep Grand Cherokee SRT8 owners.
