H&R 29250-4 Street Performance Coilover Kit

H&R's 29250-4 Street Performance Coilovers deliver a precisely engineered suspension upgrade for drivers who demand both improved handling and daily-drive comfort. Unlike conventional twin-tube shock absorbers, these coilovers are built around a mono-tube gas shock design that provides superior heat dissipation, more consistent damping response, and a more refined ride on both smooth and rough surfaces.

As the originator of the true street coilover system, H&R engineers each shock and spring as a matched unit. The progressive rate spring is designed from the ground up to complement the shock's internal valving, resulting in a fully integrated suspension system rather than a collection of mismatched components. The fully threaded shock body allows precise, tool-assisted ride height adjustment without compromising the suspension geometry or spring preload.

Key Features:

• Mono-tube gas shock construction for consistent, high-performance damping
• Lowering range of approximately 1.0 to 2.5 inches for an aggressive stance and lower center of gravity
• Fully threaded shock body allows precise, adjustable ride height setting
• Progressive rate springs matched and tuned to work with shock valving from inception
• Engineered for street use — balances performance handling with everyday ride comfort
• Suitable for daily drivers and enthusiast builds alike

H&R continues to lead the performance suspension market with decades of engineering expertise. The 29250-4 coilover kit is a direct-fit solution that upgrades your vehicle's suspension with a system tuned for real-world street performance.
