H&R 29201-3 Street Performance Coilover Kit

The H&R 29201-3 Street Performance Coilover Kit is a complete, fully engineered suspension system designed to deliver an ideal balance of lowered stance, improved handling, and everyday ride comfort. Built with H&R's mono-tube gas shock construction, these coilovers provide superior damping control and more stable damping characteristics compared to traditional twin-tube designs — and because mono-tube shocks are lighter, they also help reduce unsprung weight for more responsive handling.

At the heart of the system is H&R's exclusive dynamic damper technology, where each shock is custom-valved to work in precise harmony with a matched progressive-rate spring. The progressive spring rate starts compliant over rough pavement and firms up progressively under load, delivering controlled performance without a harsh ride. The fully threaded shock body — a true threaded shock body, not a sleeve-over imitation — allows easy, accurate ride height adjustment using the spring seats, letting you dial in the perfect stance while maintaining proper suspension geometry.

Key Features:

• Mono-tube gas shock construction for superior damping control and reduced unsprung weight
• Fully threaded shock body (true threaded body, not a sleeve-over) for precise ride height adjustment
• Custom-valved shocks matched to progressive-rate springs for a finely tuned suspension system
• Front lowering range: 1.2" – 2.1" | Rear lowering range: 1.0" – 2.0"
