H&R 29928-1 Street Performance Coilover Kit Mono-Tube Adjustable Lowering

The H&R 29928-1 Street Performance Coilover Kit delivers a premium suspension upgrade engineered specifically for street use. Built around a state-of-the-art mono-tube gas shock construction, these coilovers offer a significant advantage over traditional twin-tube shock absorbers — providing more consistent damping, better heat dissipation, and improved overall handling response.

H&R is widely recognized as the originator of the true street coilover system, and the 29928-1 continues that legacy. Each shock absorber is individually tuned and paired with a progressive rate spring designed from the ground up to complement the shock's specific valving characteristics. The result is a cohesive, finely balanced suspension system rather than a collection of mismatched components.

Key Features:

• Mono-tube gas shock construction — superior to twin-tube designs for consistent, fade-resistant performance
• Fully threaded shock body for precise, adjustable ride height lowering
• Adjustable lowering range of approximately 1.0 to 2.5 inches
• Progressive rate springs matched and tuned to the shock valving from inception
• Engineered for everyday street use — balances ride comfort with improved handling
• Suitable for daily drivers through serious performance enthusiasts

The H&R 29928-1 coilover system allows you to dial in your preferred ride height without sacrificing ride quality, making it an ideal solution for those seeking improved stance, reduced body roll, and sharper cornering response — all while maintaining day-to-day drivability.
