H&R 54735 Street Performance Coilover Suspension Kit

The H&R 54735 Street Performance Coilovers are engineered to deliver a superior balance of everyday ride comfort and responsive handling. Designed specifically for street use, these coilovers feature a mono-tube gas shock construction — a significant upgrade over traditional twin-tube shock absorbers — providing improved heat dissipation, more consistent damping, and a more responsive feel under varying road conditions.

H&R pioneered the true coilover system for street applications and remains an industry leader in suspension engineering. Each unit pairs a precision-valved shock absorber with a progressive rate spring designed from the ground up to complement the shock's specific valving characteristics. The result is a cohesive, finely tuned suspension system rather than a collection of mismatched components.

Key Features:

• Mono-tube gas shock construction for superior performance over twin-tube designs
• Fully threaded shock body allows precise, tool-based ride height adjustment
• Adjustable lowering range of approximately 1.0 to 2.5 inches
• Progressive rate springs engineered specifically to match each shock's valving
• Designed for street use — suitable for daily drivers and performance enthusiasts alike
• Improved handling response and ride comfort compared to OEM suspension

H&R coilovers are a proven upgrade for drivers seeking a lower stance without sacrificing the ride quality needed for daily use. The H&R 54735 kit delivers the performance tuning heritage of one of Germany's most respected suspension manufacturers in a package built for real-world roads.
