H&R 29471-1 Street Performance Coilover Kit

The H&R 29471-1 Street Performance Coilover Kit is an engineered suspension solution designed to deliver an exceptional balance of ride comfort and handling performance for street use. As the originator of the true street coilover system, H&R brings decades of German suspension engineering expertise to every kit — designed, built, and tested in Germany.

Unlike conventional twin-tube shock absorbers, the H&R 29471-1 uses a mono-tube gas shock construction that provides superior damping control and consistent performance in all driving conditions. The fully threaded shock body — a true threaded design, not an imitation sleeve-over — enables precise ride height adjustment and promotes better heat dissipation than competing designs using damper inserts in a threaded housing.

Each shock is custom-valved to work in harmony with a precision-wound progressive-rate spring, creating a cohesive, finely tuned suspension system. The progressive spring rate ensures a compliant, comfortable ride at all adjusted heights, while the lower center of gravity reduces body roll during hard cornering and improves overall vehicle balance.

Key Features:

• Mono-tube gas shock absorbers for precise, consistent damping response
• Fully threaded shock body for accurate, adjustable ride height — not a sleeve-over design
• Progressive-rate springs tuned to match shock valving for optimized handling and comfort
• Average front lowering of 1.6"–2.5"; average rear lowering of 1.3"–2.0"
• Lowers center of gravity to reduce body roll and improve cornering balance
• Height adjustment via easy-to-use spring seat collars
• 100% designed, built, and tested in Germany
• Backed by H&R's Lifetime Defect Warranty
• Professional installation and a wheel alignment are recommended after fitment

The H&R 29471-1 Street Performance Coilover Kit is an ideal upgrade for daily drivers and performance enthusiasts alike, delivering the stance, handling, and comfort expected from the brand that pioneered the modern aftermarket coilover.
