H&R 29865-1 Street Performance Coilover Kit - Height Adjustable Monotube Suspension

The H&R 29865-1 Street Performance Coilover Kit is a complete, height-adjustable suspension system engineered for street and occasional track use. Built on a monotube gas shock design, these coilovers deliver more precise handling response compared to conventional twin-tube absorbers, making them a popular upgrade for enthusiasts seeking both improved performance and daily drivability.

At the heart of the system is a fully threaded shock body — not an imitation sleeve-over — that allows precise ride height adjustment via easy-to-turn spring seats. This lets you dial in your exact stance and optimize weight transfer without sacrificing suspension geometry or ride quality. Front lowering range is approximately 1.25" to 2.0", with rear lowering of approximately 1.25" to 2.5".

Each shock is custom-valved and paired with a vehicle-specific progressive-rate coil spring, engineered from the ground up to work in harmony with the shock's damping characteristics. The progressive spring rate provides a compliant, comfortable ride over rough roads and firms up progressively under hard cornering or braking, reducing body roll and improving overall handling balance. Made in Germany and TÜV quality approved, these coilovers meet rigorous European safety and quality standards.

Key Features:

• Monotube gas shock construction for precise, responsive damping
• Fully threaded shock body for adjustable ride height (not a sleeve-over imitation)
• Front lowering range: 1.25" – 2.0" | Rear lowering range: 1.25" – 2.5"
• Vehicle-specific progressive-rate coil springs matched to shock valving
• Reduces body roll and lowers center of gravity for improved cornering
• Trapezoidal thread design helps prevent seizing over time
• TÜV approved — Made in Germany
• Suitable for daily drivers and performance-oriented street use

H&R pioneered the street coilover concept in the late 1970s and continues to set the standard for complete, integrated suspension systems. The 29865-1 kit is a direct reflection of that heritage — a balanced, high-quality upgrade for drivers who want real performance without compromising everyday comfort.
