H&R 29973-1 Street Performance Coilover Kit Mono-Tube Adjustable Lowering

The H&R 29973-1 Street Performance Coilover Kit is engineered specifically for street use, delivering a refined balance of ride comfort and enhanced handling. Unlike conventional twin-tube shock absorbers, H&R Coilovers utilize a state-of-the-art mono-tube gas shock construction that provides superior heat dissipation, more consistent damping response, and improved overall performance.

As the originator of the true coilover system for street use, H&R brings decades of suspension engineering expertise to every kit. Each shock absorber is individually tuned and paired with a progressive rate spring engineered 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.

The fully threaded shock body allows for precise, tool-assisted ride height adjustment, giving owners the flexibility to dial in their preferred stance without sacrificing ride quality. With an average lowering range of 1.0 to 2.5 inches, the H&R 29973-1 is an ideal upgrade for daily drivers and performance enthusiasts alike.
