H&R 29278-1 Street Performance Coilover Kit

The H&R 29278-1 Street Performance Coilover Kit delivers a refined suspension upgrade engineered from the ground up for street-driven vehicles. Unlike conventional twin-tube shock absorbers, these coilovers are built around a monotube gas-charged shock design that provides more precise damping response, better heat dissipation, and improved handling consistency over a wide range of driving conditions.

Each shock absorber is custom-valved to work in harmony with H&R's precision-wound progressive rate springs, creating a fully integrated suspension system rather than a collection of mismatched components. The progressive spring rate keeps the ride compliant over everyday road imperfections while firming up progressively under harder cornering, braking, and spirited driving loads.

The fully threaded shock body allows the spring perch to be moved up or down with precision, giving drivers the ability to fine-tune ride height independently from spring preload. H&R coilovers are hand-assembled in Germany under strict ISO 9001 and TÜV quality standards, ensuring consistent performance and long service life.

Key Features:

• Monotube gas-charged shock absorber construction for precise, consistent damping
• Progressive rate springs custom-matched to each shock's valving
• Fully threaded shock body for adjustable ride height
• Lowering range of approximately 1.0" to 2.5" (front) and 1.0" to 2.3" (rear)
• Height adjustment via easy-to-use threaded spring perch and locking collar
• Hand-assembled in Germany to ISO 9001 and TÜV standards
• Complete front and rear coilover system included

Suitable for daily drivers and performance enthusiasts alike, the H&R 29278-1 Street Performance Coilovers strike the balance between comfortable street manners and sharper handling dynamics — making them one of the most versatile coilover solutions available for street use.
