H&R 29509-2 Street Performance Coilover Kit

The H&R 29509-2 Street Performance Coilovers deliver a refined balance of everyday ride comfort and responsive handling performance. Engineered specifically for street use, these coilovers feature a mono-tube gas shock construction that provides superior damping control and more consistent performance compared to traditional twin-tube designs. Mono-tube shocks are also lighter than their twin-tube counterparts, helping to reduce unsprung weight for improved suspension response.

H&R's fully threaded shock bodies are a true threaded design — not a threaded housing with insert — which promotes better heat dissipation and allows for precise, nearly infinite ride height adjustment. Each shock is custom-valved to work in harmony with precision-wound progressive-rate springs, creating a cohesive, finely tuned suspension system that firms up progressively under hard driving while remaining compliant on everyday roads.

Key Features:

• Mono-tube gas shock absorbers for stable, consistent damping in all conditions
• True threaded shock body construction for better heat dissipation and height adjustment
• Progressive-rate springs matched and tuned to each shock's specific valving
• Adjustable ride height with a typical lowering range of 1.2" – 2.3" front and 1.0" – 2.0" rear
• Lowers center of gravity for improved cornering balance and vehicle control
• Includes adjustment wrenches for convenient ride height changes
• 2-year warranty to original purchaser

Professional installation and a post-installation wheel alignment are recommended. Note: Actual lowering height may vary on vehicles equipped with factory sport suspensions or different engine configurations. Using the kit outside of the allowable adjustment range specified in the included H&R tech sheet will void the warranty.
